TOPSIDE-LIFTING DESIGN METHOD FOR FIXED PLATFORM

摘要

The present invention relates to a method for designing a top side lifting of a fixed platform for designing a lifting of a top side module (10) with multiple decks (15). The method includes: (a) a step of setting a one side lifting point (20) of the top side module (10) to a fixed state and setting an opposite side lifting point (20) to a floating state; (b) setting a variable node (45) for the opposite side lifting point (20) of the top side module (10); and (c) determining a lifting design after applying a change in a design of the top side module (10). Therefore, the method for designing a top side lifting of a fixed platform can reduce the changed amount of COG, increase the weight allowance, minimize a hook risk, and shorten the construction period.
