Multi hull barge
Disclosed is a vessel comprising at least two parallel hulls at a predetermined mutual distance. A deck structure is supported on the hulls. Fluid storage tanks are placed in the at least two hulls, at least partly below the deck structure. The deck structure carries fluid processing and/or production equipment. The fluid is a hydrocarbon. The ratio of length to width of the vessel being at least 3, preferably at least 4. The length of the vessel being at least 150 m, preferably at least 250 m, more preferably at least 350 m.
1. A vessel anchored to the seabed via anchor lines comprising:
at least two parallel hulls at a predetermined mutual distance, each hull in use extending above water level along an elongated water line,
a deck structure supported on said hulls in the vicinity thereof, and
LNG storage tanks, wherein the LNG storage tanks are placed in the at least two hulls, at least partly below the deck structure,
a product riser extends between the vessel and the seabed for transport of hydrocarbons to the storage tanks,
the deck structure carries cryogenic processing and/or production equipment comprising a regasification plant, being in fluid connection with the storage tanks,
the ratio of length to width of the vessel is at least 3,
a length of the vessel is at least 150 m, and
a turret extending between the hulls, the turret comprising an annular support member and a central cylinder rotatably supported in the support member and connected with a lower part to the seabed via an elongate member,
