Abstract (en)
[origin: WO9747516A1] A method and a system for positioning of a floating vessel (1) against the wind and/or wave/current direction prevailing at any time, especially a vessel for the production of hydrocarbons from a subsea source. The system comprises a number of anchor lines (4-9) which, at one of their ends, are fastened to respective winches (10-15) placed in the bow (16) and stern (17) of the vessel, and at their other ends are fastened to respective anchors (18-21) anchored in the seabed at places located at chosen horizontal distances from the vessel (1) and having a chosen mutual angular distance measured along a horizontal circle with the centre in the vessel. The method consists in that the vessel by hauling-in and slackening, respectively, of chosen anchor lines by means of the associated winches is turned and oriented with its longitudinal axis (L) within an angular range of about 180 DEG , so that the bow (16) or the stern (17) is oriented against the prevailing wind and/or wave/current direction.
