Abstract: A system is described for use at offshore locations of large depth, for mooring a production vessel or floating unit (14) at a location over a hydrocarbon reservoir (26) and for connecting risers (101) that can be carrying hydrocarbons up from the sea floor to a production vessel that stores the hydrocarbons, flowlines for water injection, gas lift, gas export, umbilicals and mooring lines that moor the vessel. Both the mooring lines and the risers are disconnectably connected to the vessel though a connection buoy, or connector (16). The invention concerns a system that allows a connector (16) to be used that is of minimum mass and volume, to ease its handling especially during its connection and disconnection to and from a vessel.

Abstract: A mooring system includes a vessel with a lower-side cavity, a turret extending from deck level to the cavity, and a coupling mechanism releasably attaching a mooring buoy to the cavity, at least one buoy-supported riser. The riser end has a coupling member, the riser being slidable via a buoy opening, a riser connector member being attached to a movable transport member upwardly displaceable by a drive element, for: when the buoy and vessel are coupled, attaching the riser connector member to the transport member transporting the transport member upward while sliding the riser through the buoy and attaching the coupling member to a vessel transfer duct, and for lowering the riser while sliding the riser through the buoy until the connector member is supported by the buoy, prior to coupling member release, and release of the riser connector member from the transport member, followed by buoy lowering.

Abstract: An offshore construction includes a floating body (1), at least one anchor line (2) for connecting the floating body to the sea bed, the anchor line being connected to the floating body via a flexible top part (4) which is attached to a connector (5) on the floating body. The connector includes a housing (9) having two mutually perpendicular pivot axes (10, 12) with an elongate tubular member (8) extending in the anchor line direction and a latch mechanism (15) for fixation of the anchor line to the floating body and preventing movement in the direction of the sea bed. The connector includes a rod (13), which can be accommodated within the tubular member. The rod is connected to the flexible top part.

Abstract: A vessel (1) includes a relatively small sized turret (2) located near keel level. The upper part (3) of the turret wall is located below a level halfway between deck level (12) and keel level (7). Via a relatively small diameter product shaft (9), the product pipe (18) which connects to a riser (17) extends up to deck level (12). The lower part (6) of the turret wall extends along the height of the chain table (8), which is connected thereto via an axial and a radial bearing (23, 24). In this way the chain table (8) can adequately take up the bending moments exerted by the mooring chains (13) or cables. After use of the vessel (1) as a floating production storage and offloading vessel, the lower part (6) of the turret wall can be easily removed and the vessel (1) can be converted back to a transport tanker. Preferably the lower part (6) of the turret wall is releasably connected to the upper part (3) by means of releasable bolts (27) through the upper slide bearings (23) of the chain table (8).

Abstract: A vessel comprising a detachable buoy (3) which is connected to the vessel near keel level. the buoy or the vessel comprise on their contact surfaces an annular sealing element (6) comprising at least one inflatable tube (7,8,9). By placing the inflatable tube on the contact surfaces, the buoy and the vessel can be firmly connected, even when the contact surfaces are not completely flat. A water tight seal is formed by the inflatable tube such that the room in the top part of the buoy can be drained. Hereby a firm connection is achieved and a dry room becomes available for placing structures such as for instance a manifold system.

Abstract: Protection device for a turret bearing arranged between a floating structure and a mooring member. A turret bearing is arranged at or below water level to provide an effective introduction of forces as near the lower side of the floating structure as possible. To guarantee lubrication of the turret bearing a labyrinthine chamber is provided around the turret bearing. The downwardly extending part of this chamber is realized by the floating structure and more particularly a reinforced box whilst the upwardly extending part is provided by a wall extending from the body of the mooring member.
