Abstract

The invention discloses a bilge for an ocean engineering auxiliary ship. A contour line at a parallel middle body segment of the bilge is folded corner-shaped. Through the folded corner-shaped bilge, the width of a bilge keel can be effectively increased, so that the roll damping is greatly increased; on the premise that an anti-rolling tank and an anti-rolling fin are not installed, the seakeeping performance of the ship is greatly increased, the construction difficulty of the ship is reduced simultaneously, and the construction cost of the ship is saved.

Description

technical field

[0001] The invention relates to the technical field of an offshore engineering auxiliary vessel (Offshore Supply Vessel, OSV), in particular to a bilge for an offshore engineering auxiliary vessel. Background technique

[0002] Offshore engineering auxiliary ships need to stay at sea for a long time to serve offshore platforms, and cannot change course or shelter from the wind before the arrival of strong waves like ordinary ships, so offshore engineering auxiliary ships inevitably need to work in extremely harsh sea conditions. Along with the movement of the waves, the marine engineering auxiliary vessel also moves in six degrees of freedom. These movements will not only reduce the operating efficiency of marine machinery, but also accelerate the fatigue of the crew and reduce the work efficiency of the crew. Therefore, seakeeping (rolling, pitching, sinking, etc.), especially rolling has become an important inspection index for marine engineering auxiliary ...
