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...

Embodiment Construction

[0024] In the first specific embodiment of the present invention, a ship comprehensive balancing system is provided, which is combined with a fin stabilizer, a water stabilizer tank and an anti-heeling balance tank, so as to balance the ship to the greatest extent.

[0025] The fins of the stabilizer protrude from the two chords of the hull and are installed at a certain depth below the waterline. Its shape is similar to that of a rudder. A pair of fin stabilizers shall be arranged on the same widest cross-section of the ship, so that the center line of the fin shaft of the stabilizer intersects the ship's roll axis. When the ship sails in wind and waves and produces rolling motion, the fins are controlled by the fin stabilizer control system and rotate correspondingly according to the law of sea disturbance. After the ship is equipped with fin stabilizers, the controller can act on the fin stabilizers to change The ship's natural frequency and roll damping, thereby changing t...
