ABSTRACT:
The invention relates to a vessel which is attached to the sea floor by at least one anchor line. A riser support buoy (9) is releasably connected to the vessel. The anchor line or anchor lines are attached to the vessel outside the area of the riser support buoy (9) such that the buoy can be detached from the vessel independently from the attachment of the anchor lines. By releasing the riser support buoy while maintaining the anchor lines in place, the buoy can be released by maintenance purposes, inspection of the buoy body or the riser without the vessel going adrift. Also the forces between the vessel and the buoy are reduced as the anchor lines are not attached to the riser supporting buoy. The riser supporting buoy may be provided with stabilisation lines (45,45') which on one end comprise a ballast weight (46,46').
