多用途集装箱船的散装谷物稳性计算与衡准

Calculation and criterion of grain stability criteria for general cargo/container ship

对于能兼运散装谷物的多用途集装箱船而言 ,由于散装谷物具有一定的流动性 ,对船舶稳性产生类似于液体自由液面的不利影响。为此 IMO.MSC.2 3(5 9)—“International L oad for Safe Carriage of Grain in Bulk”提出了对散装谷物船舶的稳性衡准方法。本文结合实例 ,介绍了一型 174 5 0 DWT多用途集装箱船的散装谷物稳性的计算方法 ,供设计者计算此类船型的谷物稳性时参考。

Multipurpose container ship which is able to carry also grain in bulk is suffering from adverse affect of some kind of free liquid of surface to its stability as the bulky grain has the tendency of certain degree of free movement. Due to this reason, IMO established the stability criterion requirement for ships carrying grain in bulk in its regulation IMO.MSC.23 (59)-'International Load for Safe Carriage of Grain in Bulk'. As an example of application, the paper presented a calculation procedure for grain stability of a 17 450 tonnage multi purpose container ship. It serves a good reference for designers in designing such type of ship.
