Abstract
A mooring and cargo handling system for difficult-to-handle cargo such as liquified natural gas (LNG), is provided, which includes a swivel unit mounted on a mooring station and having rotatably connected sections respectfully coupled to a shore installation and to a ship that is moored to the mooring station. The swivel unit sections are connected by a rotary bearing and rotary outer seal, and the unit has a wall forming an auxiliary chamber extending along the bearing and seal, so that evaporating LNG must pass through the auxiliary chamber before it can escape through the bearing and outer seal. A gas pipe connects the auxiliary chamber to the ship or the shore installation where the evaporated gas can be flared or reliquified.
