Embodiment Construction

[0025] figure 1 and 2 A schematic cross-sectional view of the pontoon 1 is shown, wherein, figure 1 shows the mooring system in the connected state, while figure 2 The mooring system is shown in the disconnected state. In this embodiment, the pontoon 1 is an FPSO (Floating Production Storage on Load) pontoon. It should be understood, however, that the releaseable mooring system may also be used in other types of floating F(P)SO objects.

[0026] The breakaway mooring system comprises a mooring buoy member 2 and a turntable structure 3 mounted on a well 4 of a vessel 1 . The buoy member 2 is designed to maintain floating equilibrium at a predetermined liquid level below seawater, wherein the buoyancy capacity of the buoy member 2 is sufficient to accommodate the load of the riser and mooring lines connected to the buoy member. The buoy member 2 is anchored to the seabed in the usual manner by mooring lines 5, figure 1 and 2 Two of them are shown in . In addition, the m...

Abstract

A disconnectable mooring system for a vessel comprises a mooring buoy member (2) and a turret structure (3), mounted in a moonpool (4) of the vessel (1). The mooring buoy has a plurality of passages (6) each adapted to receive a riser (7). The turret structure has a receptacle for receiving the buoy member and locking means for locking the buoy member in the receptacle. The turret structure (3) accommodates a plurality of conduits to be connected to risers installed in passages of the buoy member and the turret structure is rotatably supported in the moonpool (4) of the vessel (1) by means of at least a bearing assembly (16) mounted above sea level. The turntable (21) is supported on the bearing assembly (16) in a manner allowing rotation with respect to the turret structure (3) to align the conduits with the risers (7) when the buoy member (2) is received and locked in the receptacle of the turret structure (3).

Description

technical field [0001] The invention relates to a detachable mooring system for a ship, comprising a mooring buoy member and a turntable structure installed on a moon pool of the ship, the mooring buoy member is anchored on the seabed and has a plurality of Each channel for receiving a riser, the turret structure has a receptacle for mounting a buoy member and a locking device for locking the buoy member in the receptacle, the turret structure accommodates a plurality of A conduit on a riser in a channel in which the turret structure is rotatably supported on the ship's well by means of a support assembly mounted above sea level. Background technique [0002] GB-A-2 285 028 discloses a breakaway mooring system of this type. In this known mooring system, the mooring buoy member is provided with a central projection which will fit in the receiving inlet of the receptacle of the turntable structure. This configuration requires that the buoy member and receiver be precisely pr...
