A tie-in system (47, 48) for tie-in of a transfer pipe (13, 14) to a support unit (12) is disclosed, where the transfer pipe (13, 14) is arranged at least partly in a body of water (19). The tie-in system (47, 48) comprises: a spool piece (61, 71) that in one end is adapted to be attached to the transfer pipe (13, 14) and in the other end to be connected to a pipe element (58, 68) arranged on the support unit (12), a chute device (59, 69) that is adapted to be attached to the support unit (12) and to accommodate the transfer pipe (13, 14) such that the chute device (59, 69) supports the transfer pipe (13, 14) and takes up and transfers vertical and transverse forces from the transfer pipe (13, 14) to the support unit (12), a tie-in device (77, 79) that is connected to the spool piece (61, 71) and is adapted to be connected to a tie-in member (76, 78) on the support unit (12) such that tension loads are transferred from the transfer pipe (13, 14) to the support unit (12). A fluid transfer system (10) comprising such a tie-in system (47, 48) is also disclosed.

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.

Marine transfer apparatus for transferring a load (12) between a vessel (20) and an offshore structure (1). A coupling part (4) is mounted to an elevated mounting point. A climbing part (8) comprising a climbing line (8a) and a locking member (10) fixed to one end of the climbing line (8a) is provided. The climbing line (8a) is feedable through the coupling part (4) until the locking member (10) locks against the coupling part (4) for forming a loadbearing connection. A drag line (5) is feedably connected to the coupling part (4) and includes a fastener (7) for attaching the climbing line (8a) for dragging it through the coupling part (4).

Provided is a method for moving an object between a platform of a wind turbine and a deck of a vessel, wherein the platform is located at a tower the wind turbine, wherein the object is moved vertically by a hoist coupled between the object and at least one fixation site the wind turbine located above the platform and the deck, wherein the object is deflected radially from the tower by a puller coupled between the object and the vessel.
