A Fiber Bragg Grating sensor network is designed to implement the real-time health monitoring of port machinery. This paper describes the system design and its application in port-machinery monitoring. The results of field test on port machinery in Qing Huangdao (China) are discussed. Through the long-term monitoring on running state, especially the structure strain of port machinery, the status of the port machinery including security and fatigue life could be acquired and estimated exactly. It could provide the foundation for the use and maintenance of port machinery, and the security of the port machinery is improved. Long-term test results show good stability and repeatability of < 8 mu epsilon over two years operation with a precision of +/- 4 mu epsilon and a resolution of 1 mu epsilon (C) 2009 Elsevier Ltd.
