Systems, devices, controllers, and methods for use in a floating production storage and offloading vessel

A windlass assembly for use in a turret system of a floating vessel, the turret system having a turret body positioned in a moon pool opening and rotatable about a center axis defined by the moon pool opening, the turret body having a mooring line storage section and a mooring line channel section, the mooring line storage section including a first opening and a first cavity, the first opening operable to receive a mooring line, the mooring line channel section being an elongated passageway for the mooring line to pass between an exterior of the floating vessel and the mooring line storage section, the windlass assembly comprising:

• a transportable windlass subsystem, the transportable windlass subsystem configured to be transportable between a plurality of locations on a top surface of the turret body, including a first location, wherein the transportable windlass subsystem is configurable to receive and control a movement of a portion of a mooring line;
• and
• a hoisting assembly, the hoisting assembly configurable to be transportable between a plurality of locations, including above the first location, the hoisting assembly having a main body, an attachable member, and an extendible member having a first end and a second end, the first end of the extendible member attached to the main body and the second end of the extendible member attached to attachable member, wherein when the hoisting assembly is positioned above the first location between the mooring line storage section and the mooring line channel section, the hoisting assembly is operable to control at least a position of a portion of a mooring line that is between the mooring line storage section and the mooring line channel section so as to be received by the transportable windlass subsystem.

A turret system for use in a floating vessel, the floating vessel having a hull and a moon pool opening, the turret system comprising:

• a turret body fixedly positionable in the moon pool opening and rotatable about a center axis defined by the moon pool opening, the turret body having:
• a top surface;
• a bottom surface opposite to the top surface;
• a first mooring line storage section, the first mooring line storage section including a first opening in the turret body top surface and a first cavity formed between the turret body top surface and turret body bottom surface, wherein the first opening is operable to receive a first mooring line, and wherein the first cavity is operable to house at least a majority length of the first mooring line;
• a first mooring line channel section formed through the turret body between the turret body top surface and turret body bottom surface, the first mooring line channel section being an elongated passageway for the first mooring line to pass between an exterior of the floating vessel and the first mooring line storage section;
• a second mooring line storage section, the second mooring line storage section including a second opening in the turret body top surface and a second cavity formed between the turret body top surface and turret body bottom surface, wherein the second opening is operable to receive a second mooring line, and wherein the second cavity is operable to house at least a majority length of the second mooring line;
• a second mooring line channel section formed through the turret body between the turret body top surface and turret body bottom surface, the second mooring line channel section being an elongated passageway for the second mooring line to pass between an exterior of the floating vessel and the second mooring line storage section, wherein the first and second mooring line channel sections are separate elongated passageways so as to enable the first mooring line and second mooring line, respectively, to be directed through the turret body to the exterior of the floating vessel without coming into contact with one another;
• a first front mooring line stopper assembly operable to receive the first mooring line, the first front mooring line stopper assembly actuatable between a stop position and a release position, the first front mooring line stopper assembly provided between the first mooring line channel section and the first opening of the first mooring line storage section;
• and
• a first rear mooring line stopper assembly operable to receive the first mooring line, the first rear mooring line stopper assembly separate from the first front mooring line stopper assembly, the first rear mooring line stopper assembly actuatable between a stop position and a release position, the first rear mooring line stopper assembly provided between the first front mooring line stopper assembly and the first opening of the first mooring line storage section;
• wherein, when the first front mooring line stopper assembly receives the first mooring line and when the first front mooring line stopper assembly is actuated to its stop position, the first front mooring line stopper assembly is operable to restrict a movement of the first mooring line through the first mooring line channel section;
• wherein, when the first front mooring line stopper assembly is actuated to the its release position, the first front mooring line stopper assembly is operable to allow a movement of the first mooring line through the first mooring line channel section;
• wherein, when the first rear mooring line stopper assembly receives the first mooring line and when the first rear mooring line stopper assembly is actuated to its stop position, the first rear mooring line stopper assembly is operable to restrict a movement of the first mooring line through the first opening of the first mooring line storage section;
• and
• wherein, when the first rear mooring line stopper assembly is actuated to the its release position, the first rear mooring line stopper assembly is operable to allow a movement of the first mooring line through the first opening of the first mooring line storage section.
