DRILLSHIP HAVING OPEN CAVITY FOR CONTROLLING UPSTREM FLOWING TO CONCAVE TYPE FLOW STABILIZER PART

摘要

PURPOSE: A drillship with an open cavity for controlling upstream flowing into a flow stabilization part is provided to control the generation of vortex and streamlined exfoliation at a flow exfoliation part of a flow stabilization part because an open cavity is installed in the upstream of the flow stabilization part to control flow flowing into the flow stabilization part. CONSTITUTION: A drillship comprises an open cavity(40). The open cavity controls upstream flowing into a flow stabilization part(30). The open cavity is formed at the bottom of a ship in a stem side of the flow stabilization part. The top of the open cavity is opened such that the open cavity can be completely opened through the bottom of the ship and the deck.
