Abstract: Bilge keel is the main anti rolling device of large heavy crane ship, which plays an important role in the stability of ship navigation and operation. In this paper, two types of bilge keel, V-shaped and flat plate, are adopted for the design of a large heavy crane ship, and the two types of bilge keel are compared and analyzed in the aspects of anti-rolling capacity, anti wave slamming capacity, manufacturing and installation process and overall cost, the V-shaped bilge keel is finally determined as the anti-rolling device of the heavy crane ship.
Key words: bilge keel; anti-rolling device; heavy crane ship; stability
