Title:
RESISTANCE-REDUCING DEVICE FOR A MOON POOL
Document Type and Number:
WIPO Patent Application WO/2011/099682
Kind Code:
A1
Abstract:
Disclosed is a lattice-shaped structure that occupies a portion of a moon pool in the bottom of a ship. While the ship moves, the lattice-shaped structure breaks waves to prevent separated water flow from being introduced into the moon pool, thereby reducing resistance applied against the ship. Since the lattice-shaped structure is a lightweight structure, the ship including the lattice-shaped structure can be efficiently towed with various towing apparatuses. Since the lattice-shaped structure can be rotated and retracted toward an inner wall of the ship, various exploration and drilling procedures can be efficiently performed through the moon pool. For this purpose, the lattice-shaped structure (16) includes a plurality of plates (20), a plurality of slopes (22), a plurality of longitudinal reinforcements (24), and a hinge (H). The plates (20) are spaced apart from each other in the longitudinal direction of the ship, and are arranged on a plurality of lines in the width direction of the ship. The slopes (22) are arranged on a plurality of lines in the width direction of the ship. An end of the slope (22) is coupled to the front end of the plate (20), and the other end thereof is inclined upward toward the front end of the ship and is spaced apart from the adjacent plate (20). The longitudinal reinforcements (24) are arranged on a plurality of lines in the longitudinal direction of the ship. Each of the longitudinal reinforcements (24) is coupled to the plate (20) and to the slope (22). The hinge (H) is used to rotate the lattice-shaped structure (16) between a sailing position and a working position in the moon pool (12).
