Ships and marine technology — Specifications for the assessment of speed and power performance by analysis of speed trial data

This document specifies requirements for the preparation, execution and reporting of speed trials of ships of the displacement type with a length between perpendiculars (L_pp) from 50 metres to 500 metres. It provides a procedure for the analysis, evaluation and correction of the gathered speed trial data covering all influences that can be relevant to the individual trial runs reporting on speed trials for ships, including effects that can influence the speed, power and propeller shaft speed relationship.
