Paper Abstract

Ice pressure is one of the most important loads in high-latitude area. It is challengeable to build a durable and stable real-time structural health monitoring system for ice-pressure under such aggressive environment as windiness, coldness, and even vibrating, which can not be met by strain gauge based sensors, whereas FBG fits it well due to its great advantage of corrosion resistance, absolute measurement, high accuracy, electro-magnetic resistance, quasi-distribution sensing, absolute measurement and so on. In this paper, a novel FBG based ice-pressure sensor has been developed. Firstly, in consideration of the monitoring of ice-pressure of offshore platform, a novel ice pressure sensor structure has been designed and it sensing principle is given in details, which theoretically shows the properties of temperature self-compensation and independence of the load position. And secondly, the properties of FBG-based ice-pressure sensor have been tested by experiments. Finally, theoretical sensitivity has been compared with that from experiments. The research results show that the FBG-based ice-pressure sensor has good linearity, repetition, immunity of temperature changes and loading position. Such kind of FBG-based ice-pressure sensor can be used to monitor ice load of offshore platform conveniently.
