The invention concerns a vessel () for storing and/or producing hydrocarbons and a buoyant turret buoy () to be connected to the vessel (). The outer surface of the bow () of the vessel () comprises a receiving structure () for connecting a buoyant turret buoy () to the bow (). The main part of the receiving structure () protrudes from the lower part () of the bow () in the vessel's () direction of travel and an interface of the receiving structure () is complementary to an interface of a connecting section () of the buoyant turret buoy (). Further the lower part () of the bow () is below the water line (w) during connection of the buoyant turret buoy () at sea. The invention also concerns a method for connecting the buoyant turret buoy () to receiving structure () of the vessel ().

Disconnectable bow turret

The invention concerns a cargo transfer vessel for transferring fluid between an offshore production facility and a tanker and a method for transferring the fluid. The cargo transfer vessel comprise a hull having a first and a second outer longitudinal hull side; a deck, propulsion means for actively maintaining the cargo transfer vessel at a predetermined distance from the offshore production facility and the tanker during fluid transfer operations and fluid transfer means for transferring fluid between the offshore structure and the tanker. The vessel is further characterized in that the hull comprises a main hull member and at least one protruding hull member arranged below the cargo transfer vessels water line at each of the outer longitudinal hull sides for suppressing roll of the vessel, wherein the at least one protruding hull member extends at least partly along the hulls longitudinal length, i.e. from the start of the vessel's bow to the end of the vessel's aft.

A tank installation for the storage of liquids, especially oil in a floating storage or production installation, including a number of tanks which are connected to pipe systems for supply of liquid to or removal of liquid from the tanks. The installation includes a central section around which the tanks are arranged in such a manner that each tank has an inner sidewall portion bordering on the central section, and the pipe systems are arranged in the central section and include radially extending pipe lengths that are connected to respective tanks.

Tank installation for the storage of liquids

Platform for drilling after or production of hydrocarbons at sea, consisting of a semi-submersible platform body which supports drilling and/or production equipment on its upper surface. The platform body is designed as a vertical mainly flat bottomed cylinder which is provided with at least one peripheral circular cut-out in the lower section of the cylinder since the centre of buoyancy for the submerged section of the platform is positioned lower than the centre of gravity of the platform.
