摘要： A work platform (10) for performing a cable operation on a cable on a vessel having a vessel deck (7) has chutes (19a, 19b) for guiding the cable from the sea and onto the work platform (10), an overboarding system (18) and a number of modules (11, 12, 13, 14, 15). Each module (11, 12, 13, 14, 15) has a deck section and a support structure for supporting the deck section at a distance above the vessel deck (7). Each module (11, 12, 13, 14, 15) is configured to be lifted separately onto and away from the vessel deck (7). The deck sections of the modules together form a mezzanine deck on which the cable operation is performed. The overboarding system (18) is secured to the mezzanine deck. At least some of the equipment for performing the cable operation is stored below the mezzanine deck.

摘要： A sliding subsea foundation comprises a polymeric shoe layer on the underside of a mudmat or subsea structure. The shoe layer defines a soil-engaging face that comprises an array of parallel grooves. The grooves are shallower than the thickness of the shoe layer such that each groove has a closed top, defined by and integral with the shoe layer, that spans the groove. Where a subsea structure is supported on the foundation with a subsea pipeline attached to the structure, the grooves are substantially parallel to a longitudinal axis of the pipeline.

摘要： A system for deploying a coil of spoolable pipe from a vessel includes a first tower configured to move longitudinally and transversely along a first track coupled to the vessel, a second tower configured to move longitudinally along a second track coupled to the vessel, and a coil drum assembly coupled to the first tower. The first tower is configured to insert the coil drum assembly transversely into an interior channel of the coil when the coil drum assembly is in a retracted position, the coil drum assembly is configured to support the coil when the coil drum assembly is in an extended position and rotate during deployment of the spoolable pipe, and the first tower and the second tower are configured to move the coil drum assembly vertically.

摘要： A device for jointing elements of a pipeline for the transport of fluids includes a support structure on which a pipeline section to be jointed is intended to be mounted, two parallel fixed rails, four plates each comprising a first element capable of cooperating with a rail and a second element fixed on the support structure. The first and the second elements of each plate is linked by a first cylinder aligned along a first adjustment axis and a second cylinder aligned along a second adjustment axis, and a system for controlling the cylinders of the plates to achieve movements along the first and second adjustment axes and capable of cooperating with a system for guiding in translation the support structure along the longitudinal axis of the pipeline section to allow jointing of the pipeline section and the pipeline element.

摘要： Disclosed are systems and methods for thermal management of subsea interconnecting conduit such as jumpers that provide cooling and heat retention of production fluids within the jumpers. In a jumper circuit, parallel sections of jumper are provided having differing amounts of heat transfer between surrounding seawater and production fluids flowing within. Valving is provided to control fluid flow between the parallel sections of jumper, thus controlling the amount of heat transfer between the surrounding seawater and the jumper circuit. A control system can be used to generate an alarm based on fluid temperature and/or fluid flow rate within the jumper circuit indicating the need to adjust the valving to manage the temperature of fluids within the jumper circuit. Changes may be needed particularly depending on the phase of production, e.g., early life, normal operation, shut down and late life operation.

摘要： The present invention relates to a pipeline junction coating between the joined ends of two coated metallic pipeline sections, the coating comprising an elongate body able to extend over the joined ends of the coated pipeline sections, and having a variable end profile at one or both ends. The pipeline junction coating is for coating field joints of coated rigid pipelines, as used in the subsea oil and gas industry.

摘要： A tensioner system holds back elongate products such as subsea pipelines being laid into water. The system comprises at least one endless circulatory track and an array of rollers supporting the track. Each of the rollers of the array is mounted for rotation around a respective shaft. At least one of the shafts comprises a load pin that is arranged to sense loads applied to the surrounding roller in directions normal to an axis of rotation of that roller.

摘要： The present invention relates to an apparatus for and a method of holding high top tension pipeline (101) during pipe-lay from a rolling and pitching vessel (730). In one implementation, a clamp system (711, 712) for supporting a pipe on a vessel includes a first clamp for coupling to the pipe and a second clamp for coupling to the pipe. The second clamp is disposed above the first clamp. At least one of the first clamp or the second clamp is movable relative to the other of the first clamp or the second clamp.

摘要： A system includes a foundation with a post mounted on the foundation top surface and a pipe module configured to couple to the foundation. The pipe module has a yoke to cooperate with the post to engage the pipe module with the foundation. The pipe module is connected to the end of a pipeline and is configured to slide along the foundation responsive to longitudinal and angular movements of the end of the pipeline.
A method includes deploying a foundation subsea and securing the foundation to a seafloor. The foundation has a post. The method includes deploying the pipe module via the pipeline suspended by a pipe module installation machine. The pipe module has a yoke. The method includes engaging the yoke with the post, paying out the pipeline to lower the yoke, and lowering and engaging the pipe module with the foundation.
