A vessel (1) comprises a rotatable turret (14) and a supporting structure (3) over or on the turret for supporting a swivel (5). The swivel comprising an inner and an outer ring (21, 21′; 22, 22′) which can rotate with respect to each other and which define at least one fluid distribution path from a geostationary fluid riser (19) connected to one ring (22, 22′) to a product outflow pipe (18) connected to the other ring (21, 21′). A rig (2) is mounted over the turret area above or below the swivel (5), and a substantially rigid pipe extends from the rig, through a moonpool of the turret towards the sea bed, the rigid pipe being in line with the swivel.

Mooring device comprising a vessel and a body carrying anchor lines which body is rotatable about a substantially vertical axis or weathervaning axis with respect to the vessel and attached to the vessel in a manner such that in case a predetermined load in one or more of the anchor lines is exceeded said body swings away with respect to the vessel in the direction of the load to avoid overloading of anchor lines and mooring device by changing the load excursion characteristic in such a way that at said predetermined load excursion can take place without the substantial change of the load.

Mooring system, comprising a ship, a mooring device, a rigid arm between ship and mooring device, which arm at one end is connected to the ship or mooring device through the intermediance of a first weight loaded connecting element, which is swingably suspended, whereas according to the invention the other end is coupled to a second weight loaded connecting element, which by its weight is held in a predensioned state aginst an abutment, such that only after a certain shift of the ship the second weight starts to function. The points of attachment of the ends of the rigid arm with the weight loaded connecting elements can be past the respective centres of gravity of the weights.

Mooring system comprising a column (2) tensioned between a sea bottom anchor (3) and a buoyant body (5-8) said column having (an) additional mass(es) (11,12,13,14,27) at the vibration node or nodes of the second or (N+1).sup.th bending vibration node(s) above the wave period while keeping the periods of the higher modes of bending vibration below or in the area of the smaller waves.

The invention relates to a mooring system, comprising a tanker (1,9,15,22,72,86,104,131) and a device (5,11,20,61,74,95,111,135) having some type of anchor (3,10,23,66,71,68,77,113,140), the tanker being rotatably connected with that device for rotation about a vertical axis (4,117). A conduit (6,24,25,45,46,122-125) extends upwardly towards that device (5,11,20,61,74,95,111,135) and towards a swivel (38,58,79,102,121) concentric with that axis (4,117) and from the swivel towards the tanker, the system having a quick connect coupling (83,84,85,91,92,97,116,117,118). The device (5, etc.) preferably has controllable buoyancy and can be of any type including a normal mooring buoy.
摘要:
A mooring system comprising a vessel (1) floating on the water surface, such as a ship, and having an arm structure (2) pivotally secured to it. A buoyant body (9) presses upwardly on the arm structure (2); and the end of the arm structure opposite the ship is pivotally connected to a connector (4-6) that extends generally vertically upward from a bottom anchor (7). The connector (4-6) is maintained under tensile stress by the buoyancy of buoyant body (9). A number of anchor chains (10) are attached to the connector (4-6) and extend down to the sea bottom in various directions and are anchored to the sea bottom at a distance from the anchor (7) to which the connector (4-6) is attached. These anchor chains (10) exert a tensile force on the connector (4-6) in the opposite direction from the force exerted by the buoyant body (9).
摘要:
Floating system comprising a ring shaped body with structure for connecting anchor chains. The ring shaped body is rotable around a vertical axis in relation to the floating system. Fluid conduits extend downwards from the floating system through the ring shaped body and are connected to a rotatable conduit coupling. The rotatable conduit coupling is installed on the floating system above the ring shaped body by a cardan joint with two horizontal axes, which cardan joint is located at the outside of the conduit coupling. The ring shaped body has an inner central opening of such large dimensions that the conduits or hoses running from conduit coupling downwards through that opening are maintained free of the ring shaped body in each angular position allowed by the cardan joint.

The invention relates to a swivel for one or more conduits comprising inner wall portions (3) and outer wall portions (2) for each annular chamber which wall portions (2, 3) are rotatably supported upon each other by means of a single axial-radial bearing the inner race way rings (7) and outer race way rings (10) of which are attached to the axial end faces of the inner (3) and outer wall portions (2) of said chamber.

An intermediate conduit extends between and interconnects adjacent pivotally connected ends of a pair of conduits. The intermediate conduit is disposed in at least one turn about the pivotal interconnection, and the distance between the ends of the intermediate conduit is substantially greater than its length. A damping device such as a dashpot interconnects the intermediate conduit and one of the pair of conduits and acts in a direction parallel to the axis of the turns of the intermediate conduit.
摘要:
A single-point mooring buoy comprises a vertical column which is secured at its lower end to the sea floor. The buoy is connected to the column for rotation relative to the column through 360.degree. about a vertical axis. A conduit extends from the lower end of the column to a swivel joint connection for a hose on the column. The buoy is mounted on the column by its own bearing, which is below that swivel joint assembly. There is a passage through the buoy in alignment with the column, which extends from above the water level to below the swivel joint.
