Automatic control system and automatic control method for ship heeling balance

Abstract

The invention provides an automatic control system and an automatic control method for ship heeling balance. Multiple anti-heeling pumps capable of independently working and multiple pairs of anti-heeling ballast tanks are arranged in the automatic control system, so that rolling of a ship in a moored condition, at various navigational speeds, such as a medium-high navigational speed, a low navigational speed and a zero navigational speed and under various encounter wave directions can be effectively reduced, and heeling and trimming caused to the ship by various factors: loading unbalance, local cabin breakage and wind pressure, are rapidly compensated, so that special engineering ships like pipe-laying ships and the like have low economic risk, can adapt to severe environment conditions, and meanwhile, have the characteristics of operational safety of offshore working, and the like. The automatic control system and the automatic control method for the ship heeling balance have very good popularization and use value.

Description

technical field [0001] The invention relates to an automatic control system and method for ship heel balance, in particular to an automatic control system and method for ship heel balance for special engineering ships in port operations and offshore operations, and belongs to the technical field of ships. Background technique [0002] At present, the comprehensive balance of special engineering ships such as pipe-laying ships is an ancient and vital subject. As an offshore mobile working platform, the pipe-laying vessel is particularly important for its comprehensive balance. With the increase in the complexity of ship missions and the application of high-tech equipment, large surface ships, as mobile platforms on the sea, require their swaying in the waves to be as small as possible so that they can safely operate in the working sea area and complete the planned tasks. work tasks. Especially for special engineering ships such as pipe-laying ships. Ships will inevitably p...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the heel and trim of the ship and the stabilizer fins that cannot be stabilized at low or zero speed, the anti-roll effect of the anti-roll tank is low, and the existing ship load adjustment control system. The potential safety hazards of the joint control pump group and butterfly valve cannot be applied to the ship crane, which makes the ship crane rely on manual experience for load adjustment, low reliability, poor safety and difficult operation. The reversible axial-flow pump-controlled ship comprehensive balance system combined with the rocking water tank and the anti-heeling balance tank and an intelligent compr
