Abstract: An automatically and remotely operable retractable mooring cleat. The retractable cleat is mountable in a surface, such as the deck, of a marine vessel. A source of motive energy forms part of an actuation mechanism energisable by a user to extend or retract cleat members from the surface. The cleat members each travel along diverging paths as they extend and travel along the same respective paths as they are retracted.

Multiple retractable cleats may be positioned about a marine vessel, each of which is operable remotely to extend or retract. Single-handed launching of a moored vessel is therefore possible.

Abstract: An offshore floating production, storage, and off-loading vessel has a hull of generally cylindrical or polygonal configuration surrounding a central double tapered conical moon pool and contains water ballast and oil and/or liquefied gas storage compartments. The exterior side walls of the polygonal hull have flat surfaces and sharp corners to cut ice sheets, resist and break ice, and move ice pressure ridges away from the structure.

The moon pool shape and other devices on the vessel provide added virtual mass for increasing the natural period of the roll and heave modes, reducing dynamic amplification and resonance due to waves and vessel motion, and facilitate maneuvering the vessel. A disconnectable turret buoy at the bottom of the moon pool connects risers and mooring lines.

Abstract: A method and apparatus for monitoring for damage to or failure of a mooring system comprising mooring lines (2) or anchors of a moored vessel (1). The vessel has a mooring point (4) to which at least one mooring line is connected. The method involves determining the geographical position of a locating point (5) on the vessel remote from the mooring point (4) and determining the heading of the vessel. The geographical position of the mooring point (4) is then calculated from the determined position of the locating point and the vessel heading. The position of the mooring point (4) is compared to at least one expected position of the mooring point (4), in order to provide an indication of failure of a mooring line (2) or anchor. The method has the advantage that failure of the mooring (lines 2) or anchors can be detected without direct monitoring of the integrity of the mooring lines (2), which is typically expensive and uses equipment that is vulnerable to damage.
