摘要： A landing system for subsea equipment includes a heavy component having a latch affixed thereto and having a mechanism attached to enable lowering the heavy component from a platform above the bottom of a body of water. A landing system frame has a connection point matable with the latch. A linear motor is functionally coupled to the landing system frame and at least one of the subsea well structure and a movable frame on the landing system. The linear motor is operable to control a distance between the landing system frame and the subsea well structure or the movable frame.

摘要： A connector adapted for release under load from a complementary connector. The connector having a locking element for engagement with the complementary connector to lock the complementary connector to the connector; and a locking member moveable from a locked position to an unlocked position. The locking member operative to permit the/each locking element to lock the complementary connector to the connector when in the locked position and operative to allow the/each locking element to release the complementary connector when in the unlocked position. The locking member and locking element arranged such that when the connector is locked to the complementary connector and the locking member is in a partially unlocked position, a load applied to the/each locking element causes the/each locking element to urge the locking member towards its fully unlocked position, thereby unlocking the complementary connector from the connector.

摘要： A retrievable module assembly can be used to install and/or de-install a blowout preventer (BOP) module from a BOP subsea where the BOP comprises one or more corresponding BOP module receivers. The retrievable module assembly typically comprises a frame configured to house and support the subsea BOP module; and a modular storage unit disposed at least partially within the frame. The modular storage unit further comprises a storage area configured to removably accept the subsea BOP module; a rotator configured to attach to and rotate the subsea BOP module, the rotator disposed at least partially within the frame; a rotator mover, slidably mounted in the frame and operatively in communication with the rotator; and a power connector operatively connected to the rotator and rotator mover and configured to interface with a power source.

摘要： A system for maneuvering a plug in and out of a tubing hanger mounts to a subsea wellhead assembly. The system includes a tractor and an end effector that are sheltered in a housing. A control cable spools from a reel mounted on the housing and attaches to the tractor. The control cable provides communication from a remotely operated vehicle (ROV) to the tractor and end effector so that commands from the ROV via the control cable control the tractor and end effector. After the housing connects to the wellhead assembly, control signals from the ROV activate the tractor to drive the end effector into the wellhead assembly and command the end effector to set the plug in the tubing hanger, or to remove the plug from the tubing hanger.

摘要： A releasable guidepost extension is used on the seabed together with a bottom fixed guidepost part. These parts make up a guidepost for use during the lowering of a component from the surface of the water to a subsea structure. The guidepost part includes an upward (in use position) projecting end designed for engagement with a lower (in use position) end of the guidepost extension. The guidepost extension is loosely connected to the bottom fixed guidepost part via a pin and socket part on respective ends. A gap, or clearance, exists between the pin and socket part in the longitudinal direction, and at least one friction forming device arranged in the gap on either the pin part or in the socket part. The friction forming device does not get in contact, or engaged, with the other part unless the guidepost extension is subjected to a lateral force.

摘要： A releasable marine tether connection comprises a tether having a segmented spring collet which can be expanded to become trapped in an anchor chamber. A spigot is provided in the base of the chamber which urges the plug upwards relative to the collet when the tether is pushed into the chamber to make the connection. To release the connection tension is removed from the tether and the plug moved down to allow the spring collet to close and move out of the chamber.

摘要： An installation comprising a base frame 1 having four locations 2 for well heads 20 and a manifold frame 10 disposed in overhanging fashion inside the zone defined by frame 1. Frame 10 has four locations 17 for a stacked pair of connecting 30 and monitoring 40 modules, as well as a central location 17' for a central control module 50. Each module is provided with guide members 26, 32, 41, 52, for example sleeves, whose geometry corresponds to that of guide devices 3, 18 placed either on guide bases 2 of the frames 1, 10 or on the underlying module, such as guide columns 18. Each module comprises on its lower face a mechanical connector 16 cooperating with a mandril 12 carried on the upper face of the underlying module. The control of locking of the connector is provided by an internal multiconnector receptacle 24, 34, 43, 57 which each module comprises. In this remote control installation, the production head zone can be separated from the functional module zone and the modules can be stacked in the order of decreasing reliability, so as to provide easy access to the less reliable modules.

摘要： A drilling rig comprises a platform (10) supported above a sea surface (14) by legs which extends to the sea bottom (16). A drill guide (30) of rigid open framework construction extends down from the platform to the sea bottom. The drill guide is only minimally affected by turbulent sea conditions because of its open framework construction. A hardenable substance such as concrete (54) is poured into a flexible bag (50) at the lower end of the drill guide to form a solid structure conforming to the uneven sea bottom and having a substantially flat upper surface. Drilling takes place through the hardenable substance and into the underlying sea bottom.
