Semi-submersible jetty for transferring LNG from a production vessel to a transport vessel

摘要

An 'L' shaped semi-submersible jetty is provided for use in the transfer of LNG from a production vessel to a transport vessel. In use the jetty is connected to the production vessel by means of a ball and hydraulic clamp coupling 3, which allows no relative motion between the jetty and the production vessel in a longitudinal, transverse or vertical direction, but does allow rolling motion of the jetty. Once the jetty is connected to the production vessel the transport vessel is moored alongside the jetty and LNG is transferred through pipes running along the jetty.
