DUAL CRANE SPREADER BEAM SYSTEM FOR MODULE LIFTING FPSO AND THE SHIP OR OFFSHORE PLATFORM INCLUDING THE SAME

摘要

The present invention relates to a dual offshore crane spreader beam system for mounting an FPSO module which can maximize lifting capacity of a crane by offsetting horizontal load generated in the crane when a heavy object is lifted using two cranes. The dual offshore crane spreader beam system includes: multiple hook beams wherein a hook connected to a dual crane by a wire is connected to a hook pin joint; a compression beam which connects the hook beam and a hook beam by an upper pin joint; a wire connected to a lower part of the hook beam; a tension bar controlling the horizontal load by being connected to a lower end of the wire; and a link plate connecting a module by being connected to both ends of the tension bar by a lower pin joint.
