重大件货物装卸中船舶稳性的计算及调整

Calculation and adjustment of stability for a heavy-lift ship

基于船舶静力学理论,推导了重大件货物装卸过程中船上重吊在任意位置时船舶稳心高度及横倾角的计算方法,分析了影响船舶稳性及横倾的基本要素,并给出了调整船舶横倾的具体方法,为船方掌握重大件货物作业中船舶稳性及横倾的变化规律并采取恰当的安全措施提供了理论依据.

Based on the principle of ship statics, the authors deduce a method to calculate the metacentre height and the inclined angle when a heavy cargo is loading or unloading by a derrick on board the ship. This formula shows the factors that influence the stability of a ship. A practical method to increase stability and reduce inclined angle is also put forward in this paper. 
