ActiveShips and marine technology—Measurement of changes in hull and propeller performance—Part 3: Alternative methods
船舶与海上技术 船体和螺旋桨性能变化测量 第3部分：替代方法
Application Summary AI generated
This standard specifies alternative methods for measuring changes in hull and propeller performance, such as torque and thrust measurements, when traditional speed trials are impractical. It is applied in the shipbuilding and marine industry for in-service performance monitoring, particularly for vessels operating under varying conditions where direct speed measurement is difficult. The standard supports maintenance planning and efficiency assessments by providing practical testing protocols for evaluating fouling or damage effects on propulsion systems.
