摘要： A flowline jumper handling apparatus for supporting a flowline jumper in a generally horizontal position as it is offloaded from a surface structure with a first lifting apparatus and then supporting the flowline jumper in a generally vertical position as it is lowered to a subsea structure with a second lifting apparatus. The flowline jumper handling apparatus comprises an elongated spreader bar, at least one first cable connecting the spreader bar to the flowline jumper, at least one second cable connecting the spreader bar to a through member, at least one third cable connecting the through member to the second lifting apparatus, at least one fourth cable passing through the through member and connecting the flowline jumper to the first lifting apparatus, and a restricting member for preventing a portion of the fourth cable from passing through the through member. In this manner, as the fourth cable is lifted by the first lifting apparatus, the restricting member will engage the through member and support the flowline jumper in a generally horizontal position. Furthermore, as the fourth cable is lowered, the flowline jumper will rotate from the generally horizontal position to the generally vertical position.

摘要： A system that is usable in a subsea well includes a tubular string that extends from a surface platform toward the sea floor. The string has an upper end and a lower remote end that is located closer to the sea floor than to the platform. At least one sensor of the system is located near the remote end of the string to monitor deployment of subsea equipment.

摘要： A pipeline (23) device, comprising at least one end for connection to a connection site, e.g., on another pipeline (22), on the seabed. A sleeve, movable in the longitudinal direction of the pipeline (23), is arranged at the end of the pipeline (23). A pull-in device (4, 36, 39) grips the sleeve (29) in order to pull the end of the pipeline (23) towards the connection site. The sleeve (29) may be arranged rotatably on the pipeline, and the pipeline may comprise a conical portion (26) into which the sleeve (29) is adapted to enter in order to center the pipeline (23) end relative to the sleeve (29).

摘要： A tensioning riser system for supporting marine elements such as risers which extend form a fixed lower end at a subsea base or foundation to a moving, floating superstructure. The tensioning system has a lever arm pivotally connected to both the superstructure and the upper end of the marine element and a tension controlling strut member pivotally connected to both the superstructure and the lever arm.
