The present invention relates to a flow resistance reducing structure in a moon pool for an offshore structure, which reduces fluid resistance caused by a moon pool in an offshore structure where the moon pool for sending drilling equipment, such as a drilling ship and a drilling unit, downward is formed, thereby reducing sloshing. According to the present invention, the flow resistance reducing structure in a moon pool for an offshore structure comprises a flow resistance reducing unit which prevents sea currents flowing along the bottom of an offshore structure from a stem to a stern from directly flowing into the moon pool.
본 발명은 시추선이나 굴착선과 같이 시추장비 등을 내려보내기 위한 문풀이 형성되어 있는 해양구조물에서 문풀에 의한 유체 저항을 감소시키고, 이에 따라 슬로싱(sloshing)을 저감시킬 수 있도록 한 해양구조물 문풀의 해류저항 저감구조에 관한 것이다. 본 발명에 따르면, 해양구조물에 마련된 문풀의 해류저항 저감구조에 있어서, 해양구조물의 선저를 따라 선수 측으로부터 선미 측으로부터 흘러오는 해류가 직접적으로 문풀 내부로 유입되는 것을 방지하는 해류저항 저감수단을 포함하는 해양구조물 문풀의 해류저항 저감구조가 제공된다.
