The OpenSSL 3. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3. Note that data sent from an OpenSSL 3. Many application protocols require data to be sent from the client to the server first. Therefore, in such a case, only an OpenSSL 3.
If both endpoints are OpenSSL 3. In this case both clients and servers could be affected, regardless of the application protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3. The confidentiality of data is not impacted by this issue, i.
In order for this attack to work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled by default in OpenSSL 3. This ciphersuite will never be used if TLSv1. In order for an OpenSSL 3. An issue has been discovered affecting GitLab versions prior to GitLab does not validate SSL certificates for some of external CI services which makes it possible to perform MitM attacks on connections to these external services.
Mbed TLS before 3. In standalone mode i. Sonatype Nexus Repository Manager 3. An issue was discovered in Rhinode Trading Paints through 2. TP Updater. Thus, attackers can man-in-the-middle a victim to download a malicious binary in place of the real update, with no SSL errors or warnings. That function may return a negative return value to indicate an internal error for example out of memory.
The exact behaviour will depend on the application but it could result in crashes, infinite loops or other similar incorrect responses. This issue is made more serious in combination with a separate bug in OpenSSL 3. This will occur where a certificate does not include the Subject Alternative Name extension but where a Certificate Authority has enforced name constraints.
This issue can occur even with valid chains. By combining the two issues an attacker could induce incorrect, application dependent behaviour. Fixed in OpenSSL 3. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. While a smuggled request is still captured as part of another request's body, it does not appear in the request list and does not go through the usual mitmproxy event hooks, where users may have implemented custom access control checks or input sanitization.
The vulnerability has been fixed in mitmproxy 7. Lynx through 2. A local attacker can overwrite arbitrary files on the system with VPN client logs using administrator privileges, potentially resulting in a denial of service and data loss, in all versions of Sophos SSL VPN client. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to a downgrade in the communications between the client and server into an unencrypted format.
The Secure attribute tells the browser to only send the cookie if the request is being sent over a secure channel such as HTTPS. This will help protect the cookie from being passed over unencrypted requests. If the application can be accessed over both HTTP, there is a potential for the cookie can be sent in clear text. A smart proxy that provides a restful API to various sub-systems of the Foreman is affected by the flaw which can cause a Man-in-the-Middle attack.

Both issues were reported to happen intermittently in heavy load TLS connections. They cause a crash, resulting in a denial of service. These are fixed in version 2. Due to an error in a third-party dependency the ssl flags used for setting up a TLS connection to a server are overwitten with wrong settings.
In Stormshield 1. Syncing the schema with the --schema-first and --schema-only options is mishandled. For example, the sslmode connection parameter may be lost, which means that SSL would not be used. The xmlhttprequest-ssl package before 1.
In other words, no certificate is ever rejected. SSL Network Extender Client for Linux before build reveals part of the contents of the configuration file supplied, which allows partially disclosing files to which the user did not have access. Nim is a statically typed compiled systems programming language. In Nim standard library before 1. Users can upgrade to version 1. Attacker on the local network can monitor traffic and capture the cookie and other sensitive information.
The urllib3 library 1. This means certificates for different servers that still validate properly with the default urllib3 SSLContext will be silently accepted. As obtaining the privileged permission, remote attackers use the leakage to abnormally terminate the Web service. An issue was discovered in Emote Remote Mouse through 4. It uses cleartext HTTP to check, and request, updates. Thus, attackers can machine-in-the-middle a victim to download a malicious binary in place of the real update, with no SSL errors or warnings.
Maven is changing the default behavior in 3. More details available in the referenced urls. If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior.
An insufficient verification of data authenticity vulnerability CWE in the user interface of FortiProxy verison 2. OpenSSL 1. A server that supports greater than SSLv2 is supposed to reject connection attempts from a client where this special form of padding is present, because this indicates that a version rollback has occurred i. The implementation of this padding check inverted the logic so that the connection attempt is accepted if the padding is present, and rejected if it is absent.
This means that such as server will accept a connection if a version rollback attack has occurred. Further the server will erroneously reject a connection if a normal SSLv2 connection attempt is made. Only OpenSSL 1. In order to be vulnerable a 1. Although 1. Applications that directly call that function or use that padding mode will encounter this issue. However since there is no support for the SSLv2 protocol in 1. Premium support customers of OpenSSL 1. Other users should upgrade to 1.
Fixed in OpenSSL 1. A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.
This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers.
In a worst-case scenario, this weakens transport security significantly. Nextcloud Desktop Client before 3. The vulnerability affects version 6. An unauthenticated attacker in the same network collision domain as the NetWorker Management Console client could potentially exploit this vulnerability to perform man-in-the-middle attacks to intercept and tamper the traffic between the client and the application server.

Although the certificate chain must contain one of a set of pinned certificates, there are certain implementation errors such as a lack of hostname verification. NOTE: this is an end-of-life product. Limesurvey before 3. A clear text storage of sensitive information vulnerability in FortiClient for Mac may allow a local attacker to read sensitive information logged in the console window when the user connects to an SSL VPN Gateway.
If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS.
For OpenSSL versions 1. For OpenSSL 1. However, some build instructions for the diverse Windows targets on 1. OpenSSL versions 1. Due to the limited scope of affected deployments this has been assessed as low severity and therefore we are not creating new releases at this time. RFC specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes.
However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored. It is a requirement of using this cipher that nonce values are unique. Messages encrypted using a reused nonce value are susceptible to serious confidentiality and integrity attacks.
If an application changes the default nonce length to be longer than 12 bytes and then makes a change to the leading bytes of the nonce expecting the new value to be a new unique nonce then such an application could inadvertently encrypt messages with a reused nonce. Additionally the ignored bytes in a long nonce are not covered by the integrity guarantee of this cipher.
Any application that relies on the integrity of these ignored leading bytes of a long nonce may be further affected. However user applications that use this cipher directly and set a non-default nonce length to be longer than 12 bytes may be vulnerable. An issue was discovered in JetBrains TeamCity It had no SSL certificate validation for some external https connections.
This was fixed in TeamCity A vulnerability was found in keycloak 7. The mAadhaar application 1.

Referring still to FIG. The diverter control system accumulator can be charged with BOP control fluid by the HPU from precharge pressure up to the system's operating pressure. The accumulator bottles working pressure can be about 5, psi, and can be rated up to about 6, psi or more.
According to some embodiments, the accumulator bottles can be arranged on manifolds that allow for isolation of a bank of accumulators for maintenance. Each manifold can be complete with a liquid filled pressure gauge panel with a block and bleed manifold valve, 4-bolt split-flange type ports for the accumulators, and a single relief valve. In addition, accumulator bottles can be of a top loading design, which allows bladder removal and maintenance without removal from the unit.
In addition, the skid frame can be freestanding and constructed of welded carbon steel coated with a paint system suitable for marine service applications. Referring to FIG. Technology related to that shown and described in FIG. As shown in FIG. Each of these components is described in detail below. The assembly typically attaches to the bottom end or near of the riser above the flex joint, with a bracket that bolts on using existing mounting holes on the riser adapter.
These outputs can be filtered and passed to the ship board control system for processing and display. The gas handler system is a specialized annular closing device typically positioned below the telescopic joint The gas handler system can add capabilities to the standard diverter system.
When the gas handler system receives hydraulic fluid via a gas handler reel , which acts on the system to close the internal annular packer, the system's gas vent line then opens. The top of the gas handler system is oriented towards the female riser connector and has six lines. The bottom of the gas handler system can be oriented towards a male riser connector, and can have up to five lines.
One feature typically included in a gas handler system is the main body, which houses the piston and elastomers providing the gas handler with its sealing ability. As the piston rises, the internal annular packer closes and seals against any shape located inside the riser, or defines an open hole. The riser pipes are typically welded to flanges, which in turn are connected to the gas handler body by stud bolts or other appropriate fasteners.
The auxiliary lines can be stabbed into the body. In some embodiments, hold down plates can be provided around each line to prevent unstabbing of the periphery lines under high internal pressure. The gas handler system can be rated to handle up to about 2, psi The riser of the present technology can be rated up to about 4.
Of course, the pin and box ends of the pipe body could be reversed. The couplings can have support plates, which provide support for the choke, kill, and auxiliary lines, and which provide a landing shoulder for supporting the weight of the riser string on the riser spider during installation or retrieval operations.
Riser joints can be supplied in various lengths up to about 90 feet. Auxiliary lines on the riser joints can be supported by clamping bands, which can be spaced out between the support plates, and fastened around the riser pipe. The lines can be terminated with male or female stab subs which are held in alignment by the coupling support plate.
In some embodiments of the present technology, the box coupling of each riser joint can be equipped with dog segments that are driven into a grooved profile on the pin by the movement of a cam ring. This provides a large axial locking force to preload the connection.
Cam ring movement is accomplished by the riser spider, discussed in greater detail below. The pin coupling can incorporate an alignment key that mates with a slot in the inside diameter of the box coupling and that can provide about 5 degrees of rotational alignment for stabbing the couplings together. The riser can be fitted with foam buoyancy modules for deep water operations.
According to some embodiments, some features of the riser are as follows:. The Telescopic Joint is designed to compensate for vertical movement and offset of the drilling vessel. It can also serve as a connection point for the marine riser tensioners part of the tensioning system , and a crossover leading to the diverter system In some embodiments, the telescopic joint can consist of five major subassemblies, including: 1 the crossover with hydraulic latch, 2 the inner barrel, 3 the dual packer housing, 4 the outer barrel, and 5 the fluid assist bearing.
Each of these subassemblies is discussed in greater detail below. The crossover assembly can have a standard riser coupling and a hydraulically actuated latch ring. The riser coupling can connect the riser string to the diverter system, and the hydraulic latch ring can lock the inner barrel to the outer barrel for handling, storage, and hangoff.
The hydraulic latch ring can consist of six hydraulic cylinders and support dogs plumbed together, that when latched, can support the full tensile rating of the telescopic joint The crossover can be equipped with a tapered locking nut and special keys to secure and prevent rotation of the mating inner barrel.
In some embodiments, the locking nut can have left hand threads, and can be split to facilitate disassembly from the inner barrel. According to some embodiments, the dual packer housing can contain two pressure activated seal elements. Pressure can be applied to each packer through ports. An upper seal element can be split, and is generally activated with rig air.
Such upper seal can provide primary leakage control during normal drilling operations. The lower seal element can be solid, and replacement typically requires the disassembly of the crossover assembly. A top flange can mate with the hydraulic latch dogs when the joint is fully collapsed. In addition, the top flange can also be equipped with lubrication ports that allow a fluid lubricant to be introduced, which can extend the life of the seal elements.
The outer barrel subassembly can have a primary function of providing a means to apply tension to the marine riser string suspended therebelow. According to some embodiments, an upper portion of the outer barrel can have a thick-walled section where the fluid assist bearing is attached. At the very top of the outer barrel can be a flange for attachment of the dual packer housing assembly.
The lower end of the outer barrel can have a thick-wall section to prevent collapse should the outer barrel contact the hull of the vessel. The fluid assist bearing can contain an annular chamber, which can be pressurized when making vessel heading changes. This reduces the torsional loads induced into the riser and wellhead from vessel rotation.
The rotatable outer housing and fixed stationary piston can be sealed using redundant high performance swivel seals. The locking dogs can mate with a profile inside the riser box coupling. The tool can have a fail-safe rising stem design that is activated by a hydraulic cylinder to latch or unlatch the tool. The tool can also be equipped with a swiveling lifting padeye near the center of gravity, with lift point options and a mechanical lock to keep the tool locked in position if latch pressure is lost during use.
In some embodiments, the gimbal , which can be associated with a shock absorber unit, can provide up to about six degrees of gimbal action at mid-stroke, by transferring hydraulic fluid from cylinder to cylinder in a closed system. This allows a load suspended from the riser spider to remain stable and independent of pitch and roll of the drilling vessel within the design limits of the system.
The gimbal and shock absorber unit greatly reduces the shock loading on the marine riser system when landing the riser in the spider, by gradually reducing landing velocity and dissipating the energy into the hydraulic system accumulators. The spider sits on top of the gimbal and shock absorber unit, and, for safety and other reasons, can be designed to minimize the intervention of rig floor personnel.
In many embodiments, the spider provides three primary functions, including: 1 hang off of the riser string during running or retrieving, 2 automated make up and preload of the riser coupling connection, and 3 to provide a hang off position for change out of the slip joint upper packer.
In some embodiments, the spider consists of two sections, including a lower and an upper section. The lower section typically performs the hang off function by extending six dogs into the bore and hydraulically locking them in place. The upper section can utilize six actuation arms to engage the riser cam ring, and lock or unlock the couplings between riser sections.
According to some embodiments of the present technology, the spider can include one or more of the following features:. In addition, the spider can be associated with a control system, including:. According to some embodiments of the technology, the adapter ring can interface with the telescopic joint to provide a means to apply tension to the deployed marine riser string, while easily connecting and disconnecting certain marine riser hydraulic functions e.
This can be accomplished with pressure actuated pin stabs for each hydraulic function between the adapter ring and the telescopic joint adapter. In some embodiments, the adapter ring allows the rig tensioner lines to remain connected and properly spaced out during riser deployment and retrieval.
In addition, the adapter ring can reduce or eliminate the time associated with attaching and removing the standard telescopic joint auxiliary line goosenecks. Some embodiments include a fluid assist bearing FAB in the adapter ring allows the rig to rotate relative to the wellhead without imposing excessive torque on the riser string. The adapter ring can be designed to attach to the diverter support housing using stow dogs when not in use. The LMRP can be releasably connected to the lower stack by a hydraulic connector.
Such a scenario may occur, for example, where a hurricane or other conditions necessitate temporary removal of the LMRP from the lower stack to prevent damage to the system. According to some embodiments, the BOP stack subsystem can include a frame having lifting eyes The frame can also have two-point lifting capability, which allows the frame have the ability to be split into two parts. In some embodiments, the entire stack can be retrievable from either a horizontal or vertical position, and the frame can have a wellhead connector position indicator to provide easy viewing of the connector operations.
In some embodiments, the BOP stack subsystem has a three-piece frame design, including a one-piece LMRP and a two-piece lower stack including upper and lower portions. Various BOPs are attachable to individual rather than multiple levels of the frame, allowing the stack to be split without removing all the BOPs.
Additionally, hydraulic manifolds are provided at each level of the frame; this allows sections of piping to be readily attached to the manifolds when the frame is assembled, simplifying installation and maintenance operations. The three-piece design also facilitates transportation of the BOP stack subsystem components from the site of manufacture to the drill ship or platform. In some embodiments, the BOP stack subsystem is configurable as a 6 , 7 , or 8 cavity stack.
If desired by the user, the configuration can be modified in the field after initial deployment. Configurability of the stack enables a user to add or subtract BOP cavities based upon the needs of each wellsite, such as for reasons related to weight, the specific subsea wellhead being used e. Because the stack is modular and includes strategically placed connections, in order to replace a damaged or worn BOP, a user can swap a portion of the stack, rather than pulling apart the entire stack, thus reducing down time.
In some embodiments, the frame can be a fabricated steel frame painted with a three part epoxy subsea coating. In addition, the frame can include yoke type hangoff beam supports, and one ladder can be included to provide access to the top of the pedestal. In some cases, the pedestal can include padeyes, which can interface with crane lifting blocks. The frame of the LMRP can be designed to support the mounting of acoustic sensors for monitoring the annulars. Each of these features is discussed in greater detail below.
Typically, such functions are carried out by an ROV as a backup, if the surface controls are not functioning properly. Such pipe can be rated to about 20, psi or more. The valves can be hard pipe, as opposed to flexible hose style, and can be designed and supported to allow full lower flex joint rotation at MWP. Some embodiments of the technology also include a single gate gas bleed valve to provide gas relief.
All of the hydraulic mechanisms and the seals can be contained in the female stab connection mounted on the LMRP In some embodiments, the female connector is in the retracted position when the LMRP is landed and mated to the lower stack. According to some embodiments, when the female connector is retracted, there can be a minimum of two inches clearance between the bottom end of the female connector and the top of the male stab.
The male stab connection can be mounted near the top of the lower stack frame to align with female stab connection on the LMRP A difference in bore seal diameters provides a bore pressure generated force to maintain the connection. For some embodiments of the present technology, specifications for the stab connections can be as follows:.
According to some embodiments of the present technology, the LMRP connector can have the following specifications:. The riser adapter can consists of a main body with upper and lower connections to form a crossover between the marine riser and the LMRP Provisions for the riser instrumentation, such as the inclinometer and slope indicator, and a main bore wear bushing, may be included.
The entry manifold on the booster line with a gate valve for testing provides the capability to inject fluids into the riser bore through the riser adapter In some embodiments, the riser adapter can include a series of hydraulic cylinders that move a cam ring in order to lock or unlock the connection with a series of dog segments. Manual secondary locks can provide backup to the primary lock, and can be rated to the full unlock load of the hydraulic cylinders at psi.
In addition, the hydraulic circuit can incorporate two depth compensation cylinders to prevent a pressure differential from occurring within the circuit. Two ball valves can also be included for rapid venting of the circuit if required, but remain closed otherwise. Additional control or ROV panels may be included if desired.
The annulars can be a dual annular, hydraulically operated annular type BOP. In addition, the annular BOP body can also include lift eyes equipped with shackles, each with a safe working load SWL rating of 55 tons per shackle minimum, for lifting the annular BOP. In addition, the probes can have an external hydrostatic pressure rating of about 12, ft.
In some embodiments, the power and communications hub can encapsulate the functionality of the power distribution and Ethernet based communication. Embodiments of the LMRP subsea control module can control up to about hydraulically related functions or more.
The hydraulic pod section of the LMRP subsea control module can be constructed of corrosion resistant stainless steels. Furthermore, dynamic components can be constructed of corrosion resistant anti-galling stainless steels.
In addition, the pod internal subassemblies can be arranged to provide full access to ensure maintenance and service efficiency. Furthermore, a manifold can provide the hydraulic connection with the pod male stab and the upper and lower receptacles through high-pressure packer seals and retainers. High pressure fluid can be delivered via the SPM valve transfer spool to the interface manifold. In turn, the fluid can be distributed to the particular outlet port via the upper receivers or transferred to the lower receivers via porting in the male stab.
A safety pin can be included that can secure the pod male stab in the upper position during installation, removal, or handling of the POD off the stack. In operation, the pod can receive hydraulic fluid from the rigid conduit manifold or the hotline.
Hydraulic supply to the rigid conduit manifold in turn can come from the rigid conduit s and the stack accumulator system. The lower valve unit manifolds can be mounted in a horizontal tiered array providing easy access to mounted components for service or maintenance. In some embodiments, the hydraulic pod section of the LMRP subsea control module can include up to five regulated hydraulic control circuits or more, which can be mounted in each control pod.
These regulators can be manufactured from anti-galling and corrosion resistant stainless steel and can be hydraulically piloted. The five regulator functions are: 1 stack connector pressure regulator, 2 upper annular pressure regulator, 3 lower annular pressure regulator, 4 subsea manifold pressure regulator, and 5 ram manifold pressure regulator.
In addition, in some embodiments, modular stainless steel manifolds for regulated and unregulated functions can be provided. The valves can be hydraulically connected with formed and welded L stainless steel pipe spools, with modified split flange hubs containing radial o-ring seals. In addition, the SPM valves can interface to the male stabs via L stainless steel pipe spools containing modified hubs with seal sub profiles.
In some embodiments, the hubs can have double radial o-ring seals and 4-bolt forged stainless steel split flanges. In some embodiments of the present technology, the LMRP disconnect indicator can consist of an LMRP disconnect actuator, and an arm operated shear seal valve. Both can be mounted to the lower valve unit of the MUX Pod. Upon separation of the LMRP , the spring-loaded pin extends, causing a hydraulic signal to be transmitted to a pressure transducer and a pressure switch in the MUX Pod.
The pressure switch can then provide an immediate signal to activate a riser recoil system via a dedicated twisted-pair circuit in the MUX cables. In some embodiments, the valve and actuation pin can be constructed of anti-galling, corrosion resistant stainless steel. The instrumentation, as well as all interface wiring, can be located internal to the pod SEMs. In addition, the lower stack can include a guide funnel, to help provide deep water guidelineless drilling.
The lower stack frame can be designed to carry all components of the lower stack. In some embodiments, the lower stack frame can be composed of fabricated steel, painted with a three part epoxy subsea coating. In addition, it can be manufactured with yoke type hangoff beam supports, and can include retractable padeyes that interface with crane lifting blocks.
The ROV intervention panel is designed to allows an ROV to perform the following functions via an access panel mounted to the lower Stack frame :. Furthermore, the ROV can have the ability to recharge the subsea accumulators. The lower stack HPHT probes can use a 2-wire device interface to the power and communications hub on the lower stack The lower stack can also include a wellhead connector , which, in some embodiments, can have the following features:.
There is included in the lower subsea control module the power and communications hub , lower stack pod receivers, and ROV display , an APCS , and readback pressure switches, among other components. According to certain embodiments of the present technology, the lower subsea control module accounts for the power and communications needs as applied to the lower stack The design of the lower subsea control module as well as the stabs connecting the LMRP and lower stack accounts for critical and non-critical functionality to ensure separate circuitry for both the power and communication.
These receivers can be constructed of, for example, galling and corrosion resistant stainless steels. Corresponding BOP receivers can be spring-loaded, and can be bolted to a welded companion flange on the bottom of the BOP plate. The receiver can also provide function ports for the BOP hydraulic components. Under normal operations, each ram position and pressure can be transmitted to the surface for operator display.
In addition, in some embodiments, a battery backup can be provided to the display in case a loss of power occurs. The battery can deliver power to the ROV display for up to about 30 days or more. In alternate embodiments, the ROV display can provide a wetmate connector that can allow the ROV to power the display. In yet other embodiments, the design can provide an illuminated display only when an ROV is present, in order to preserve energy and battery life.
Another feature of the lower subsea control module is the APCS The APCS can contain a portable emergency system for shutting in the well. This is accomplished through the use of sonic signals sent from the surface rig floor, lifeboat, or helicopter to a subsea acoustic control pod that executes critical BOP function commands to shut in the wellhead in the case of the loss of the MUX control system. The surface and subsurface portions of the APCS communicate via unique sound signals transmitted and received through transceivers connected to acoustic transducers.
In some embodiments, a pod simulator allows the operator to test and evaluate the control system for proper operation without using the actual subsea acoustic pod. In practice, in some embodiments, the subsea transducers receive acoustic signals generated by the acoustic command unit through a dunking transducer. The subsea transducers can be mounted, one each, on hydraulically actuated arms that attach to the stack.
With the stack on the sea bottom, the arms can be extended to horizontal orientations to receive signals from the surface. The electrical voltages resulting from the subsea signal conversions actuate solenoid operated valves in the acoustic pod.
These actuations produce the hydraulic pressures required to shut in the wellhead and other functions. As each actuation occurs, the pod forwards an electrical confirmation signal for conversion and transmission to the SCUs. Each confirmation signal updates the visual display of pod status in the SCUs. Structurally, the subsea acoustic pod can have an upper cylindrical solenoid housing bolted onto the lower stack hydraulics.
The solenoid housing, frame, external plating and some internal parts of the lower box can be made from stainless steel, or any other appropriate material. Internal pod components can include solenoid assemblies, pressure switches, a hydraulic filter, an accumulator, and an SPM valve manifold.
The subsea acoustic pod can have an electrical cable interface to the Subsea ACS electronic container. The electrical cable interface can provide commands to the solenoids, and readback from the pressure transducers and pressure switches. These functions include:. The lower stack and the LMRP can be connected to one another by a hydraulic connector , which can be controlled to allow disengagement of the LMRP from the lower stack An upper end of the LMRP is connected to a riser that extends from the upper end of the LMRP to a vessel at the surface of the sea.
Also included in the system can be a first control pod often referred to as the yellow control pod and a second control pod often referred to as the blue control pod. In the embodiment shown in FIG. The first control pod and second control pod can be controlled by first and second control cabinets , , located on the vessel The vessel can be any appropriate vessel, including, for example, a drill ship or a platform. Under normal operations, the subsea BOP rams are hydraulically controlled by the first or second pod , Specifically, hydraulic lines run from each of the first and second control pods , to individual rams of the BOP Typically one of the two control pods , is responsible to hydraulically control the rams through its respective hydraulic lines , while the other control pod , remains idle.
In this way, redundancy is built into the system because if the control pod , actually controlling the rams becomes incapacitated, or otherwise requires maintenance or replacement, the other control pod , can continue operation of the rams One purpose of such a system is to provide the appropriate SIFs to confirm and backup the BOP control system, and comply with certain regulatory standards applicable to many systems and sub-systems in the petroleum industry.
The SIS includes a surface logic solver , or logic controller, located at the vessel , and connected to a first subsea logic solver by a first cable The first subsea logic solver is in turn connected to a second subsea logic solver by a second cable In some embodiments, the second subsea logic solver can be connected to a battery, so that the second subsea logic solver can continue to operate after the LMRP has been disconnected from the lower stack The surface logic solver can include an HMI panel to allow an operator to communicate with the surface logic solver In practice, the surface logic solver can generate commands, which are then transmitted to the first subsea logic solver via the first cable From the first subsea logic solver , the commands are then transferred to the second subsea logic solver , which communicates with, and may be attached to, the hydraulic control unit The hydraulic control unit is in turn in communication with the subsea BOP rams via hydraulic lines The second subsea logic solver can implement the commands, directing the hydraulic control unit to control the subsea BOP rams as desired by an operator.
The logic solvers , , of any embodiment described herein can be any equipment capable of sending and receiving signals according to the requirements of the technology. For example, in some embodiments, the logic solvers can comprise or include central processing units CPUs.
In the embodiment shown, each ram can be connected to multiple hydraulic lines , each coming from a different control source, including the first control pod , the second control pod , and the hydraulic control unit As shown, which line controls the BOP ram at any given moment can be controlled by valves attached to the BOP rams In the drawings, hydraulic lines are shown connecting each of the first and second control pods , and the hydraulic control unit to some, but not all, of the rams It is to be understood that in a functioning system, each of the control components can be connected to all of the rams , and such a configuration is not shown in the drawing only to improve clarity of the figures.
One benefit of the SIS described above is that it provides additional redundancy to the system, and acts as a failsafe to enhance safety and reliability of the BOP. Although two control pods , are already provided to create some redundancy in the system, in reality it can be difficult to use the second control pod if the first control pod is out of commission. This is because government regulations and best practice procedures dictate that a backup control system always be in place for the BOP.
Thus, if the first control pod is unavailable, the second control pod cannot be used because there would be no redundancy. The SIS herein described helps to alleviate this problem by providing a second redundant control system. In addition, the SIS of the present technology can serve to augment the capabilities of the overall system by providing additional means to control the BOP rams , even when both control pods , are functioning properly.
For example, the SIS, via the hydraulic control unit , can control certain rams at the same time that the control pods , are controlling alternate rams Thus, the capacity of the system to control the BOP rams is increased. Furthermore, the system can provide monitoring functions, such as monitoring various states, statuses, parameters, etc. The technology can also be designed to comply with the requirement of high pressure drilling operations, and can be used, for example, with a 20 Ksi BOP system, although it is not limited to such systems, and may be used in other types of systems as well, such as 15 Ksi systems.
In addition, the SIS, as described herein, is a different type of control system than the primary control system, thereby providing the additional advantage of increasing the diversity of the control architecture. Some benefits of the present technology can now be described. In order to understand the benefits, however, it is first important to understand some of the requirements of offshore drilling systems, one of which is to allow disconnection and subsequent reconnection of the LMRP from the lower stack This can be beneficial, for example, when a hurricane or other storm threatens a drilling vessel or platform.
To weather such a storm, an operator may wish to disconnect the LMRP from the lower stack , and move the LMRP , riser and vessel out of harm's way. After the storm passes, it is necessary to then reconnect the LMRP to the lower stack to resume operations. The disconnection and subsequent reconnection of the LMRP to the lower stack can be greatly simplified by reducing the number of connections between these components, and also by controlling the types of connections made.
One way to simplify the reconnection of the LMRP and the lower stack is to provide a pair of subsea logic solvers, as shown in FIG. This is because the first cable , which connects the surface logic solver to the first subsea logic solver must carry power and communications between these two components. Often, the distance between the surface logic solver and the LMRP and thus the first subsea logic solver through the riser can be very long, such as up to about 2 miles in length or more.
Thus, power lines in the cable must be relatively high voltage lines, and the communications are often carried through optical lines although copper lines may be used. If the system were equipped with a single subsea logic solver in the lower stack, an operator would need to disconnect and reconnect both higher voltage power lines and fragile optical communications lines between the LMRP and the lower stack Such connections could be dangerous in the case of the high voltage power lines and could degrade the quality of the communication signals in the case of the optical communications lines.
Alternatively, if the system were equipped only with a single subsea logic solver on the LMRP , multiple hydraulic lines would need to cross from the LMRP to the lower stack to connect to the rams Such a structure could be problematic because of the need to disconnect and reconnect many more lines between these components. By providing two separate subsea logic solvers , , including one on the LMRP and one on the lower stack , these problems can be alleviated. In practice, according to the present technology, the cable connecting the surface logic solver to the first subsea logic solver can include high voltage power lines and optical communication lines.
One function of the first subsea logic solver can be to convert and lower the voltages, and to convert the optical signals to copper, thereby allowing communication between the first subsea logic solver and the second subsea logic solver 44 to be through low voltage copper wires that make up cable Such low voltage copper wire can more easily be disconnected and reconnected as needed at the interface between the LMRP and the lower stack In some embodiments of the invention, the hydraulic control unit can be connected to the hydraulic connector to disconnect or reconnect the LMRP from the lower stack Since the hydraulic connector is attached to the LMRP , a single hydraulic line may need to cross the interface between the LMRP and the lower stack to provide hydraulic communication between the hydraulic control unit and the hydraulic connector Alternatively, use of such a line can be avoided in favor of providing power to the hydraulic connector from an accumulator which, in the embodiment shown, can be attached to the LMRP It is to be understood that these explanations are given by way of example only, and do not represent all of the possible ways that that the present technology can be applied in practice.
The pipe ram function may be initiated by any contact closure input, or by an HMI panel. The need to close the ram is determined by the operator, so the initiation of the function is determined by the man-in-the-loop. When the surface logic solver on the vessel recognizes the input, it may monitor a surface flow meter or subsea sensor.
If the BOP is not successfully closed by the BPCS, the surface logic solver may transmit a signal to the first subsea logic solver The first subsea logic solver may in turn transmit the signal to the second subsea logic solver , which may fire a function that vents the open hydraulic pressure to the pipe ram and applies close pressure to the pipe ram, thus closing the BOP. The need to close the ram is determined by the operator, so initiation of the function is determined by the man-in-the-loop.
When the surface logic solver on the vessel recognizes the input, it may monitor the surface flow meter or subsea sensor. If the BOP is not successfully closed by the BPCS, the surface logic solver may transmit a signal to the first subsea logic solver , which may in turn transmit the signal to the second subsea logic solver If the BOP is not successfully closed by the BPCS, the surface logic solver may transmit a signal to the first subsea logic solver , which in turn may transmit a signal to the second subsea logic solver The fourth example explains an example of the function of the SIS as it relates to the hydraulic connector The hydraulic connector function may be initiated by a contact closure input, or by an HMI panel.
The need to release the LMRP is determined by the operator, so initiation of the function is determined by the man-in-the-loop. If the hydraulic connector is not successfully released by the BPCS, the surface logic solver may transmit a signal to the first subsea logic solver , which may in turn transmit a signal to the second subsea logic solver The second subsea logic solver may fire a function that vents the latch hydraulic pressure to the hydraulic connector and applies unlatch pressure to both the primary and secondary unlatch functions.
The need to disconnect is determined by the operator, so initiation of the function is determined by the man-in-the-loop. When the surface logic solver on the vessel recognizes the input, it may monitor the surface flow meter, or other sensors on the stack, for each function sequentially. If the EDS function is not successfully completed by the BPCS, the surface logic solver may transmit a signal to the first subsea logic solver , which in turn may transmit a signal to the second subsea logic solver The subsea logic solver may then fire the following, or another similar sequence, of functions:.
Also included in the system can be a first control pod A often referred to as the yellow control pod and a second control pod A often referred to as the blue control pod , and a hydraulic control unit A. The first control pod A and second control pod A can be controlled by first and second control cabinets A, A, located on the vessel A. The vessel A can be any appropriate vessel, including, for example, a drill ship or a platform. Under normal operations, the subsea BOP rams A are hydraulically controlled by the first or second pod A, A.
Typically one of the two control pods A, A is responsible to hydraulically control the rams A through its respective hydraulic lines A, while the other control pod A, A remains idle. In this way, redundancy is built into the system because if the control pod A, A actually controlling the rams A becomes incapacitated, or otherwise requires maintenance or replacement, the other control pod A, A can continue operation of the rams A.
The embodiment of FIG. The SIS includes a surface logic solver A, or logic controller, located at the vessel A, and connected to a first subsea logic solver A by a first cable A, and a second subsea logic solver A by a second cable A. The surface logic solver A can include HMI panel A to allow an operator to communicate with the surface logic solver A. In one embodiment, the HMI panel A can be a panel with push buttons and lit indicators, while other embodiments can include a touch screen display.
The hydraulic control unit A is in turn in communication with the subsea BOP rams A via hydraulic lines A. In the drawings, hydraulic lines A are shown connecting each of the first and second control pods A, A and the hydraulic control unit A to some, but not all, of the rams A.
It is to be understood that in a functioning system, each of the control components can be connected to all of the rams A, and such a configuration is not shown in the drawing only to improve clarity of the figures. As discussed in more detail above with respect to the embodiment of FIG.
The disconnection and subsequent reconnection of the LMRP 18 to the lower stack A can be greatly simplified by reducing the number of connections between these components, and also by controlling the types of connections made. This is because the first and second cables A, A, which connect the surface logic solver A to the first and second subsea logic solvers A, A, respectively, must carry power and communications between the LMRP A and the lower stack A.
Often, the distance between the surface logic solver A and the LMRP A and thus the first and second subsea logic solvers A, A through the riser A can be very long, such as up to about 2 miles in length or more. Thus, power lines in the cable must be very high voltage lines, and the communications are often carried through optical lines. If the system were equipped with a subsea logic solver in the lower stack, an operator would need to disconnect and reconnect both high voltage power lines and fragile optical communications lines between the LMRP A and the lower stack A.
In practice, according to the present technology, the cables A, A connecting the surface logic solver A to the first and second subsea logic solvers A, A can include high voltage power lines and optical communication lines.
Such low voltage copper wire can more easily be disconnected and reconnected as needed at the interface between the LMRP A and the lower stack A. In some embodiments of the invention, the hydraulic control unit A can be connected to the hydraulic connector A to disconnect or reconnect the LMRP A from the lower stack A.
Since the hydraulic connector A is attached to the LMRP A, a single hydraulic line A may need to cross the interface between the LMRP A and the lower stack A to provide hydraulic communication between the hydraulic control unit A and the hydraulic connector A. Alternatively, use of such a line can be avoided in favor of providing power to the hydraulic connector A from an accumulator A which, in the embodiment shown, can be attached to the LMRP A.
More particularly, the present technology provides a surface logic controller B, which, among other things, can monitor the basic processes and controls of the BOP system, including the performance of the subsea logic solvers, the operation of the BOP rams, the operation of shuttle valves, pressure sensors, temperature sensors, and other components of the subsea system. To monitor the operation of the BOP rams, the surface logic controller B can monitor the operation of the control pods.
According to the embodiment of FIG. The key switch can be a physical switch or can be software code integrated into the code of the logic solver. When the key switch B is in the man-in-the-loop state, the surface logic solver B, and hence the SIS for controlling the subsea BOP, can be controlled by an operator who issues commands to the surface logic solver B through an HMI panel B or by other appropriate means.
Thus, the operator can have full control over whether to initiate action using the SIS or not to initiate action. Alternatively, when the key switch B is in the automatic state, an automatic controller B can used to control the subsea BOP through the SIS described above. The automatic controller can act without prompting by the operator. Each of the reels can be controlled from a control console , which can be a remote control console.
The control console can provide for the following positions for each reel: 1 reel in, 2 brake, and 3 reel out. In addition, in some embodiments, the control console can be provided with filtered regulated air from the ship's air supply. In some embodiments, the gas handler reel can be designed to accommodate up to about one thousand feet 1, ft of 2.
The hose can be a bundle of two lines encased in a polyurethane jacket, and the hose bundle can have a minimum bend radius of about 15 inches. The reels can be mounted on a fully seam-welded, carbon steel oilfield type skid with overhead headache rack and four point pad eyes for normal offshore crane handling.
The frame can be fabricated from carbon steel, and coated with a three-coat protective coating system. In addition, the reel drive system can include a pneumatic operated drive system for both the reel drum and level-wind drives, and the brake system. The level-wind system can be mounted to a removable sub-frame on the reel frame, and can be driven by the rotation of the reel's main shaft. The level-wind system can be pitched and synchronized to the specific size of the hose.
In some embodiments, the level-wind system can consist of an Archimedes or diamond screw, with a traveling carriage supported by pillow block bearings with grease fittings , and mounted to a sub-frame. The level-wind screw can have an adjustment assembly for manually adjusting the position of the traveling carriage to correct slight deviations in timing with the reel drum.
The traveling carriage carries resilient rollers, which control and contain the hose being spooled out from the reel. Each cable reel can be furnished with about 11, ft of BOP MUX control cable , although the length of the cable can vary depending on the well. The cable reels can be designed to allow control from a remote location and provide an override for manual control.
The MUX cable can be constructed using any appropriate wire such as, e. Single mode optical fiber Primary and Secondary communication can be used for Ethernet based communications. In some embodiments, the cable can be constructed with an overall high density polyurethane cover and contra-helical, double-wound armor sheath. There can be two lengths of 11, feet of cable supplied one designated for the blue spool and one designated for the yellow spool , each would on a separate reel.
In addition, a gooseneck assembly, including a gooseneck and gooseneck clamps, can be mounted to the riser via a three piece segmented clamp, or by any other appropriate means. In some embodiments, two goosenecks sized to the appropriate bend radius of the MUX cable and hotline hose can be installed on the segmented clamp, in which case both goosenecks can have a double clamp to hold a MUX cable and hotline hose.
The goosenecks can be mounted via a double pin hinge arrangement to position the goosenecks in several positions as needed. There is shown in FIG. The testing can provide the ability to confirm the secondary stack is fully functional, and help meet the requirements of government regulators for periodic testing prior to drilling deployment. In practice, the ASTS can consist of cabinets that contain testing hardware and software. The ASTS can be connected to a secondary stack via an umbilical that contains the same hardware connections as the surface control subsystem.
During testing, the ASTS tracks the usage of all moving components involved in the testing, and, upon completion of the testing, the data is transmitted to a central repository big data for condition monitoring purposes. The data can then become part of a full life cycle tracking process. A more detailed context chart showing the big data system is shown in FIG.
Configure a Local Loopback. When you suspect a hardware problem, take the following steps to help verify if there is a problem. To diagnose a suspected hardware problem with the Ethernet interface, follow these steps:. You can create a physical loopback or configure a local loopback to help diagnose a suspected hardware problem.
Creating a physical loopback is recommended because it allows you to test and verify the transmit and receive ports. If a field engineer is not available to create the physical loopback, you can configure a local loopback for the interface. To create a physical loopback at the port, connect the transmit port to the receive port using a known good fiber cable. Make sure you use single-mode fiber for a single-mode port and multimode fiber for a multimode port.
When you create and then test a physical loopback, you are testing the transmit and receive ports of the PIC. This action is recommended if a field engineer is available to create the physical loop as it provides a more complete test of the PIC. You need the following equipment to create the loopback:. Figure 1 illustrates how to create a loopback plug for an RJ Ethernet interface. To configure a local loopback without physically connecting the transmit port to the receive port, follow these steps:.
When you create a local loopback, you create an internal loop on the interface being tested. A local loopback loops the traffic internally on that PIC. A local loopback tests the interconnection of the PIC but does not test the transmit and receive ports. On an Ethernet interface, you cannot create a remote loopback, therefore there is no option to use a local or remote statement. Simply including the loopback statement at the [edit interfaces interface-name fastether-options gigether-options] hierarchy level, places the interface into local loopback mode.
Display the status of the Fast Ethernet or Gigabit Ethernet interface to provide the information you need to determine whether the physical link is up or down. The sample output shows that the link is up and there are no alarms in this loopback configuration. When an internal loopback is configured, the physical loopback should come up without an alarm. When you see that the physical link is down, there may be a problem with the port.
The sample output shows that the physical link is down and there are active alarms and defects. Table 2 presents problem situations and actions for a physical link that is down. The transmit port is not transmitting within the dBm optical range per the specifications.
Verify that the Tx power of the optics is within range of the PIC optical specification. Verify that a single-mode fiber cable is connected to a single-mode interface and that a multimode fiber cable is connected to a multimode interface. This problem does not always cause the physical link to go down; errors and dropped packets are sometimes the result.
Remove the static ARP entry at the end of the loop test after you have completed the tests and monitored interface traffic. You can reset the Fast Ethernet and Gigabit Ethernet interface statistics. This command clears the interface statistics counters for the Gigabit Ethernet interface only. The sample output shows that the time to live TTL expired, indicating that the link is receiving the frames from the ping test.
The MAC address used is the same as the physical address of the port being tested because this allows the port to accept the frames from the ping test. As the packet is looped over the link, you expect to receive a TLL exceeded message for each ping sent.
These messages are generated because the ping packets are repeatedly looped between the router and the physical loopback. When the packet is sent to the other end of the link, which does not exist, the loopback returns the packet back to the same interface, where it is again subjected to the Packet Forwarding Engine fabric for routing.
After the route lookup, the TTL is decremented, and the packet is again sent out of the looped interface. This process repeats until the packed is either lost, or the TLL expires with subsequent TTL expired message displayed. Should any errors occur, the packet is discarded and a time-out error is displayed, rather than the expected TTL expired message. This means a given test packet must be successfully sent and received 63 times before a TTL expired message can be generated.
The two ends of the cable should be connected to the TX and RX ports of the adapter the order does not matter , thus forming a loop. The loopback connector for the eri device is a standard RJ connector. To reach the following dialog box, right-click on the test name in the System Map and select Test Parameter Options.
