摘　　要：为便于进行海上作业,海上工程船常采用月池进行设备海上布放。月池内流场较为复杂,对船体水动力性能有一定的影响。采用模型试验方法,针对不同月池方案对海上工程船的静水阻力和耐波性等水动力性能的影响进行研究。通过对不同月池形态和装载状态船模的静水阻力、横摇阻尼和波浪中的运动进行测试,比较不同月池方案模型的阻力性能及其在不同航速和不同浪向角下的运动差异,分析月池形态对海上工程船水动力性能的影响。研究结果表明,月池能增大船体静水阻力,其中方形月池的阻力性能较优,带缺口月池方案在低速工况下的阻力性能相对较优,加装月池之后船体的耐波性能得到改善。For more convenient operations on the sea,some equipment used to be deployed from the moonpool of the offshore engineering ships.The flow field in the moonpool is relatively complex,which will have a certain impact on the hydrodynamic performance of the hull.The model test is carried out to study the influence of different moonpool schemes on the hydrodynamic performance of the offshore engineering ships such as calm water resistance and seakeeping.The calm water resistance,roll damping and motions of the ship models are tested in different moonpool shapes and ship loading conditions.By comparing the resistance performance of different moonpool models and the differences in motion at different speeds and different wave angles,the influence of the shape of the moonpool on the hydrodynamic performance of offshore engineering ships is analyzed.The research results show that the moonpool will increase the calm water resistance of the hull.The calm water resistance of the block shaped moonpool scheme is relative lower,while the notched moonpool scheme has relatively better resistance under low speed conditions,and the seakeeping performance can be improved for the hull with moonpool.
