Abstract
The invention discloses a double-crane combined crane monitoring system and a control method for a semi-submersible crane ship.
Description
Technical Field
The invention relates to the field of monitoring, in particular to a double-crane combined hoisting monitoring system and a control method for a semi-submersible crane ship.
Background
The semi-submersible offshore dismantling platform is mainly applied to dismantling work of offshore large-scale platform equipment, and the lifting capacity requirement of the lifting platform is not lower than 4000 tons. The offshore large crane differs from the onshore crane in that its carrier floats on the sea, and the crane ship is absolutely not as simple as putting the crane on the ship, and it is the carrier of the crane. The crane causes the center of gravity to move when lifting heavy objects, and the movable range of the center of gravity of any floating structure is limited, so that the center of gravity needs to be controlled by adjusting the position and the quantity of ballast water in order to prevent overturning. Therefore, a safe and reliable crane monitoring system is essential to the safe operation of the hoisting platform.
At present, a traditional crane monitoring system only monitors a single crane and one aspect of the crane, and cannot effectively monitor a crane lifting platform on the sea. For example, a position monitoring system is only used for monitoring and controlling a lifting point of a crane to lift an object; or a load monitoring system is used for monitoring and controlling the bearing load of the crane; or the inclination of the suspension arm of the crane is monitored and controlled by a pose monitoring system.
However, when the semi-submersible offshore dismantling platform is used for dismantling at sea, the platform is mainly used for combined hoisting work of double cranes. The operation condition of the crane is complex, and the offshore crane is subjected to additional loads caused by high-frequency motions (rolling, pitching and heaving) of a parent ship and positioning problems caused by low-frequency motions (rolling, pitching and heading) in the hoisting process. Only a single crane and a certain aspect of the crane are monitored, which is far from enough, and the combined hoisting of the double cranes must be monitored and the ballast monitoring system is matched for combined monitoring. For example, when a heavy crane is operated with a load, the ballast dispensing capability is required to be fast because the change in the center of gravity is large. If the monitoring system cannot timely and effectively monitor and can automatically and timely adjust according to the state of the ship, the safety and the stability of the platform cannot be guaranteed.
