Promor’s scope included the conceptual and detail design for an external turret to be used on an FLNG unit moored in deep water.

The scope included the design of the main structural sections of the shaft and turret head, swivel stack detail design, chain stopper details, winch and rigging arrangements for handling the mooring lines and risers, piping systems and E&I components. Turret design was coordinated with the production department at SHI for fabrication and assembly.

The mooring system utilized a 3 X 3 arrangement with polyester mooring lines terminating in suction piles. The chain stoppers were of a Promor dual axis type to allow for out of plane bending of the top chain and chain pull through during hook up and re-tensioning.

Complete turret system was designed as a single lift assembly for integration with the rigid arm structure on the FLNG unit.
