METHOD FOR ANALYSING MOTION OF MOORING LINE METHOD FOR ANALYSING MOTION OF OFFSHORE STRUCTURE

摘要

The present invention relates to a method of analyzing the motion of a mooring line in consideration of a collision with a sea floor. More specifically, the method of analyzing a mooring line for allowing a floating structure to moor, wherein the floating structure floats on the sea, includes a step of analyzing the collision of the mooring line with the sea floor using constraints. The constraints include a non-invasive constraint in which the vertical coordinates of the mooring line are equal to or higher than the sea floor and a slope constraint condition in which the slope of the mooring line at the position colliding with the sea floor is 0.
