SAFETY EVALUATION OF DOLPHIN MOORING SYSTEM OF HYBRID SEMISUB MEGAFLOATS

摘要

The hybrid semisub megafloat has been studied for an offshore floating airport. It consists of a semisubmersible type VLFS (semisub megafloat) and a pontoon type floating structure. The semisub megafloat constitutes a runway and is constructed on the offshore side where severe wave condition exists with expecting the wave breaking effect. The pontoon type structure constitutes an apron accommodating airport terminals, etc. supporting heavy equipment and structures. In this paper, the object of study is focused to the runway of semisub megafloat, and the safety evaluation of its mooring system is carried out.
