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.
