An anchor system is initially installed upon the bed of a body of water. Permanent mooring lines are then connected to the anchor system and extend upwardly for support by a buoyancy system located below a lowest portion of the offshore platform and a zone of high oxygen content water adjacent the surface of the body of water. Sacrificial mooring lines are connected to an upper portion of the buoyancy system and extend upwardly through internal conduits with the plurality of bouyancy columns of the floating platform. In the event one of the sacrificial mooring lines becomes damaged the line may be selectively released from the buoyancy system, drawn up through a corresponding interior column and replaced from the deck of the platform. | |
