船舶和航海技术.通过测量轴变形测定船舶推进系统的轴功率.第2部分:光学反射法
This document specifies a procedure to determine the shaft power of engine ships, by measuring the shaft distortion using an optical reflection 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, including the calibration procedure, and specifies the on-board documentation for the device.
