CHAIN TENSIONING ARRANGEMENT FOR TURRET MOORED VESSEL

摘要

A single hoisting mechanism (114) is positioned on a turret (100) of either an external or an internal turret mooring system for an FSO or FPSO vessel. The mechanism is mounted for angular rotation about the center-line (116) of the turret in order that the hoist can be angularly aligned with anchor leg chains (110) or riser/umbilicals spaced around the turret.
