A method and system for heading control during ship-to-ship (STS) transfer of liquefied natural gas (LNG). A method for heading control during STS transfer of LNG while moored on a buoy includes berthing a floating storage regasification unit (FSRU) to a buoy at a forward end of the FSRU, holding a stern of the berthed FSRU at a first heading with a bow of the FSRU pointing into a current, docking an LNG carrier (LNGC) alongside the berthed FSRU, mooring the LNGC to the berthed FSRU in a double-banked configuration at the first heading, adjusting the first heading of the FSRU and moored LNGC to a second heading with the bow of the FSRU and a bow of the LNGC pointing into a swell, and transferring LNG from the LNGC to the FSRU while the FSRU and moored LNGC are pointed into the swell.

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.
