某型交通艇船舶污底对航行性能影响的实船试验分析

Effect of Traffic Boat Fouling on Navigation Performance Based on Sailing Test Analysis

针对某型交通艇因船舶污底导致航速下降的问题,采用分阶段实船试验的方法,采集螺旋桨清洁后以及水线下船底清洁后的航行数据,分析水线下船体污损和螺旋桨海生物附着对航行性能的影响程度,试验结果表明,螺旋桨海生物附着为主要影响因素,在使用维护中应优先关注螺旋桨附着海生物的检查与清理。

Aiming at the problem of decrease in the speed of a certain traffic boat caused by ship fouling,a phased sailing test method was adopted to collect sailing data after the propeller and the bottom of the ship under the waterline was cleaned.The degree of influence of ship hull fouling and marine organisms attached to the propeller on navigation performance was analyzed.The test results showed that the attachment of propeller sea creatures is the main influencing factor;in use and maintenance,priority should be given to the inspection and cleaning of marine organisms attached to the propeller.
