船舶与海上技术 船体和螺旋桨性能变化测量 第2部分：默认方法
Application Summary AI generated
This standard specifies a default method for measuring changes in hull and propeller performance over time, focusing on the impact of fouling, corrosion, or damage on ship resistance and propulsion efficiency. It is applied in the maritime industry for sea trials, in-service monitoring, and performance benchmarking of commercial vessels such as tankers, bulk carriers, and container ships. The method provides a standardized baseline for comparing performance data across different ship types and operating conditions, supporting maintenance planning and fuel efficiency optimization.
