摘要:
A chain connector for holding a chain (14) that moors a vessel to the sea floor under perhaps 2000 tons tension, which can be quickly disconnected in an emergency by applying a moderate disconnecting force such as 50 tons. The chain is held by ratchets (24, 26) that are mounted on arms (34, 36). The arms have upper ends (35) that are pivotally mounted on a housing (38) and have free lower ends (44), with the lower ends being held by cams (50) on locking dogs (52) that have locking dog lower ends (51) pivotally mounted on the housing and free upper ends (60). A hydraulic actuator (70) has pins (58) that engage the upper ends of the locking dogs to prevent the arms and dogs from pivoting apart until the locking dog upper ends (60) are raised.

Vessel (14) comprising a hull (3), a shaft (2) extending from an upper part (40) of the hull to a bottom (41) of the hull, a turret (1) being rotatably supported in the shaft via a turret bearing (4,5), a manifold support structure (31) carrying one or more conduits being rotatably supported on the turret via a manifold bearing (32), the turret comprising (1) a cavity (42) for receiving a mooring buoy (11) carrying one or more risers (12) and one or more vertically displaceable actuation members (33) near the manifold bearing (32) for vertically displacing the manifold support structure (31) relative to the turret (1) between a rotational position in which the manifold support structure (31) can rotate relative to the turret via the manifold bearing (32) and a locked position in which the bearing support structure (31) is rotationally locked relative to the turret.

Connector (12) for releasably attaching two hydrocarbon ducts, the connector comprising first and second connector members (7,8), each connector member (7,8) having a housing (18,19) with a fluid passage (40,41), a valve (42, 43) rotatably seated in the passage for closing off the fluid passage, drive members (21,22) attached to a respective valve (42,43) situated at an outer surface of the housing for rotation of the valves between an open state and a closed state, each drive member (21,22) comprising a displacement device (50,51) movable in an axial direction (A) of the housing (18,19) and a first and second force element (53,54, 55) coupled to a respective displacement device (50,51), wherein in the coupled state of the connector members (7,8), the displacement device (51) of the second drive member (22) engages with the displacement device (50) of the first drive member (21) to place the first and second drive members (21,22) in an axial opening position in which the valves (42,43) are opened and the force elements (53,54) are in a compressed state, and wherein upon axial retraction of the second displacement device (51) away from the first connector member (8), the first and second displacement devices (50,51) are movable by expansion of the force elements (53,54) to an axial closure position in which the valves are closed.
摘要:
A mooring leg connector for use with a mooring leg extending up from the sea floor to connect a floating structure to be moored to the seabed wherein disconnection and connection of the mooring leg is done by pulling in and out a connector elongated body extending in the mooring leg direction. The connector has a latch mechanism for fixation of the mooring leg to the floating structure to be moored and preventing movement in the direction of the seabed, and a flexible part with a double articulation axis located at the bottom of the connector body above the attachment member, the connector body being received in a housing which is fixed to a part of the structure to be moored, wherein the latch mechanism includes guiding elements and followers or orientation pins between the body of the connector and the housing.
