The invention provides a semi-submerged ship ballast water distribution optimization method for exploring an initial stability limit, and belongs to the technical field of ship and ocean engineering. Taking the proportion of ballast water loaded in each ballast tank as a decision variable, and taking the maximum initial stability height of the semi-submerged ship after free liquid level correction as an objective function; constructing a ballast water distribution and initial stability optimization model of the semi-submerged ship by taking displacement limitation, ship body forward floating, initial stability height limitation and rolling period limitation as constraints; performing linear conversion on a discontinuous piecewise function and a quadratic polynomial in the semi-submerged ship ballast water distribution and initial stability optimization model; solving the ballast water distribution and initial stability optimization model of the semi-submerged ship after linear conversion, and obtaining the initial stability height of the semi-submerged ship after free liquid level correction and a corresponding ballast water distribution scheme; the loading position of the goods on the deck of the semi-submerged ship is optimized through sensitivity analysis; and drawing a corresponding relation graph of the screened cargo loading position and the optimal initial stability height, and marking the optimal loading position of the cargo in the graph.

    本发明提供一种用于探索初稳性极限的半潜船压载水分配优化方法,属于船舶与海洋工程技术领域。以各压载舱装入压载水比例为决策变量,以自由液面修正后的半潜船初稳性高度最大为目标函数;以排水量限制、保证船体正浮、初稳性高度限制以及横摇周期限制为约束,构建半潜船压载水分配与初稳性优化模型;对半潜船压载水分配与初稳性优化模型中非连续分段函数以及二次多项式进行线性转化;求解线性转化后半潜船压载水分配与初稳性优化模型,获得自由液面修正后的半潜船初稳性高度以及对应的压载水分配方案;通过敏感性分析优选货物在半潜船甲板上的装载位置;绘制筛选后的货物装载位置与最优初稳性高度的对应关系图,在图中标识出货物的最优装载位置。
