Ships and marine technology — Determination of the shaft power of ship propulsion systems by measuring the shaft distorsion — Part 3: Elastic vibration method

This document specifies a procedure to determine the shaft power of engine ships, by measuring the shaft distortion using an elastic vibration type device. It gives the principles of the measurement, the components of the device and the calculation method. It also describes the factors for determining the measuring accuracy and specifies the on-board documentation for the device.
