Single Buoy Moorings Inc. Developed LNG Toroidal Swivel for LNG Transfer

LNG transfer with weathervaning Offshore LNG Terminals is now feasible. SBM has completed an in-house, three-year development program for the world’s first LNG Toroidal Swivel.

This swivel with its central opening is vital for any marine transportation system where LNG has been transferred for import or export through a weathervaning system, whether it is turret or single point mooring. The design can be configured to allow the passage of multiple LNG streams up to 20 in. and a 16-in. vapor return.

Due to composite material bearings and thermal rods inside the toroid, the swivel sealing function is shielded from thermal deformations when cooled to its 165-degree Celsius operating temperature and 10.5-bar pressure.
