为防止半载情况下矿砂船在大风浪中因操纵性能差出现摇荡剧烈的现象,以-艘半载2 ×10^4 t 精铁矿的矿砂船压载方案设置为实例,从船舶总纵强度校核和油耗效能等方面对部分压载和平行压载进行 了比较.计算结果表明,两种方案均满足船舶总纵强度的安全要求,但部分压载方案的排水量较小,能有 效降低船舶油耗,具有现实的推广意义.In this paper, we choose the example of a 20000-dwt fine ore carrier to discuss its two ballast-ing plan schemes, namely partial and parallel ballast ing, in order to prevent the ore carrier from danger in se-vere waves from dangers. The longitudinal strengths of the ship and fuel consumption performances are com-pared for those two ballast schemes. Calculations show that both schemes can satisfy the requirements of the safety of the ship in terms of the total longitudinal strength. However, the displacement of the ship is smaller in the partial ballasting scheme, hence increasing fuel consumption efficient. So this scheme is more practical.
