Off-shore mooring and fluid transfer system

摘要

Apparatus for transferring cryogenic fluid from a first vessel ( 5 ) to a second vessel in an offshore environment. The apparatus includes a semi-submersible floating dock with variable buoyancy structure ( 14, 15 ) operable to alter the draught of the dock, enabling it to be lowered in the water and raised again to engage the dock with the second vessel. A single point mooring system ( 3 ) is attached to the dock. At least one rigid cryogenic pipeline is attached between the first vessel and the dock via flexible connections. A structure ( 12 ) for transferring cryogenic fluid from the dock to the second vessel.
