CONE STRUCTURE OF SUBMERGED TURRET LOADING SYSTEM WHICH ARE ESTABLISHED IN THE VESSEL

摘要

PURPOSE: A cone structure of a STL(Submerged Turret Loading System) installed on a ship is provided to have uniform joint surface between an upper coupling ring and a lower coupling ring as the upper coupling ring and the lower coupling ring are separately coupled on a cone-shaped body part. CONSTITUTION: A cone structure of a STL installed on a ship comprises a body part(120) and a joint. The body part forms the internal space for containing a submerged buoy. The joint is integrated with the body part. The joint ahs a ring shape. The body part and the joint are formed by casting. The joint comprises an upper coupling ring(130) which is formed on the upper part of the body part and has vertical inner surface.
