全天候大功率海洋救助船快速性试验研究

Rapidity Research on Model Test of All-Weather Large-Power Ocean Salvage Vessel

全天候大功率海洋救助船(南海救101)主要用于海上遇难船舶的人命救生、以海上人命救生为目的的救助拖曳和消防灭火等救助作业,所以要求船舶具有较高的应急救助航速。本文简要介绍该船在研发设计中,针对已定主机功率和大装载量限制条件,为达到22kn应急救助航速,在船舶快速性能方面所做的研究工作。在研究设计中,对该船进行了不同主尺度、不同吃水、不同纵倾浮态、带导管螺旋桨和不带导管螺旋桨、双桨推进和三桨推进等不同船型方案的船模试验和分析研究。

This paper briefly introduced the rapidity research during the process of design for all-weather largepower ocean salvage vessel, which is under the conditions of fixed main engine power, heavy loading and the speed of 22 kn. The results and analysis of model tests with different principal dimensions, drafts, trim, propeller with and without nozzle, two and three propellers were presented.
