Offshore Moorings
|
Offshore mooring buoys are commonly
used on the UK Continental Shelf. A Single Point Mooring buoy
(SPM) as seen on the right, is used by a shuttle
tanker to secure to during loading/unloading operations.
The buoy is attached to the subsea facility by flexible risers
and is held in place by anchors and should be given a
wide berth at all times.
The images below show different mooring facilities used by FPSO's. This is a turret system
which is hauled directly up into the hull of the vessel. Transfer
of cargo takes place by shuttle tankers attached to the FPSO.
