船舶破舱进水及其影响因素

Flooding of damaged hold and its affecting factors

为了在船舶因发生碰撞、触礁、搁浅等海上事故导致破舱进水问题对事故船舶的抗沉性快速地作出适当评价依据流体力学基本原理建立了船舶破舱瞬时进水速度及进水量的数学模型,分析了破损参数及装载条件对破舱进水参数的影响.通过编程对船舶在不同破损及装载条件进行了实际计算,得出了相应的破舱进水参数,从而为船舶驾驶人员作出正确施救对策提供可靠依据,对保证船舶安全具有重要意义.

Hold flooding could occur owing to ship's collision,grounding or striking. In order to assess its insubmersibility and judge its safety,calculating model of instant flooding velocity and total flooding quantity is constructed factors affecting flooding parameters and their regularity are analysed. Ship's flooding parameters under different damaged and loading conditions are calculated by program,which provide reliable basis for captain to make decision of rescue.
