DISCONNECTABLE MOORING SYSTEM AND METHOD FOR DISCONNECTING OR RECONNECTING IT

摘要

Disconnectable mooring system and method for disconnecting or reconnecting it5A disconnectable mooring system for a vessel ispresented, comprising a moonpool in the vessel, a turret structure mounted for a rotation in said moonpool and a buoy member having a plurality of passages each adapted to re 10 ceive a riser. The turret structure has a lower end compris ing a buoy receptacle for detachably receiving the buoy mem ber, wherein the mooring system further comprises a plural ity of mooring lines for transmitting mooring forces and each have a lower end and an upper end connected to the sea 15 bed and the buoy member, respectively. The mooring lines each comprise a first section which in a disconnectable man ner is connected to the turret structure and a second sec tion connected to the first section at a coupling point and connected to the buoy member. The length of the second sec 20 tion between said coupling point and its connection to the buoy member is chosen such that when the buoy member is re ceived in the buoy receptacle with the first section con nected to the turret structure and in a state for transmit ting mooring forces, said second section is in a slack state25 not loaded by said mooring forces. Also methods for discon necting and reconnecting such a mooring system are pre sented.FIG. 1
