摘要： A subsea pipeline coated with a thermally insulating coating has a radially outer surface shaped to define external hold-back formations. In a J-lay operation, the weight load of a pipeline catenary is held back using a complementary bushing or clamp of an installation vessel engaged with the hold-back formations. The weight load is transferred from the catenary to the bushing or clamp by shear forces acting through the coating. The coating extends continuously along the pipe and is interposed between the hold-back formations and the underlying pipe. The hold-back formations may be integral with the coating.

摘要： Embodiments, including apparatuses, systems and methods, for automatically attaching and detaching seismic devices to a deployment cable, including a plurality of autonomous seismic nodes. A node installation system may include a moveable node carrier coupled to a cable detection device and a node attachment device that is configured to move a direct attachment mechanism on a node into a locking or closed position about the deployment cable. In an embodiment for retrieval and/or detachment operations, the system may also be configured to automatically detect the position of a node and remove the node from the deployment line by actuating the direct attachment mechanism into an open or unlocked position. Other devices besides a node may be attached and detached from the deployment line if they are coupled to one or more direct attachment mechanisms.

摘要： A method of handling a discrete elongate subsea element of determinate length, such as a spool of rigid pipe is disclosed. The method includes shortening a tensile chord system acting on longitudinally-spaced locations on the element to apply longitudinally-compressive forces to the element. The compressive forces bend the element along its length against elastic recovery force to shorten the span of the element. One end of the element is anchored at a first anchorage before or after the element is bent. The other end of the element is anchored at a second anchorage, after the element is bent and while the element remains bent. The method is apt to be used during installation of the element, where the anchorages are both underwater, and during transportation of the element, where the anchorages are hang-off platforms of a surface vessel.

摘要： An apparatus for positioning an underwater pipe includes a plurality of fixing members for disposing on an outer circumferential surface of the underwater pipe in a spaced apart manner, a submersible unit connected to one of the fixing members, and a counterweight unit. The submersible unit is configured to float the underwater pipe on a water surface and submerge the underwater pipe. The counterweight unit is connected to the other one of the fixing members when the underwater pipe is submerged for positioning the underwater pipe on a bottom of a body of water.

摘要： A method is provided for installing a pipeline on the seabed from a marine pipelaying vessel, including initiation, pipelaying, and abandonment of the pipeline. An embodiment of the abandonment of the pipeline includes halting pipelaying and engaging a hang-off clamp with the pipeline at a position below one or more tensioners, transferring the weight onto the hang-off clamp and holding the seagoing pipeline in the firing line, severing the pipeline, connecting the initiation cable to the lower end of the pipeline held by the one or more tensioners, transferring pipeline tension onto the initiation cable, releasing the one or more tensioners, so that a section of the pipeline is held in the firing line between the pipeline diverter and the initiation cable, vacating the firing line by at least displacing both the pipeline diverter and the initiation cable sheave and thereby displacing said section of the pipeline from the firing line, arranging the A&R cable in the firing line, connecting the A&R cable to the upper end of the seagoing pipeline held in the firing line, releasing the hang-off clamp, and operating the A&R winch and thereby lowering the pipeline onto the seabed.

摘要： A method and apparatus are disclosed for at least partially repairing a defect in a tubular composite layer. The apparatus comprises a plurality of independently movable abutment elements (3820) each supported in a spaced apart relationship via a respective one of at least one support member (3810). Each abutment element is associated with a respective drive axis along which the abutment elements are movable and the drive axes of all abutment elements extend outwardly from a common centre point.

摘要： A riser assembly and method of installing a riser assembly are disclosed. The riser assembly includes a first attachment element connected to a first portion of flexible pipe and a second attachment element connected to a second portion of flexible pipe. The first attachment element and second attachment element are connected by at least one tether element, via a fixed structure in a configuration such that, in use, in response to movement of the first and second portions of flexible pipe, the tension load at any moment in time, at each attachment element, remains substantially equal.

摘要： A method for installing an accessory onto a pipeline to be laid on the seabed, includes launching the pipeline from a first position of a tower in which the tower is at an angle α with respect to the vertical; stopping the launch of the pipeline, and hanging off the launched pipeline in a hang off module; positioning an accessory in a tower firing line; attaching the accessory to the launched pipeline in the hang off module and to at least one A&R cable; suspending the accessory and the launched pipeline from an A&R system; disengaging the hang off module from the launched pipeline; pivoting the pipeline launch tower to an accessory launch position in which the tower is at an angle γ that differs substantially from angle α, such that a pipeline launch trajectory is created which is large enough to launch the accessory and the launched pipeline with the A&R system.
