The exact power managements for a shaft of a vessel are needed for energy-saving operation of the vessel from cost reduction and global environment problems, and energy-saving regulation in international marine transportation. It is necessary to measure strain which occurs in a revolving shaft in order to control exact power and to transmit multipoint measurement data out of a system from the revolving shaft. But, it is not easy to measure power of the revolving shaft. The optical fiber sensing systems are used for structural health monitoring. The optical fiber can have functions both as a sensor, which can measure strain and temperature at different locations, and a transmission path. Therefore, strain distribution can be measured with higher accuracy. Here, the monitoring system for the revolving shaft which measures the multipoint data from the optical fiber attached to the revolving shaft is proposed. We confirm the performance of the shaft power measurement system using the optical fiber.
