Abstract

Structural health monitoring (SHM) is becoming increasingly important for marine assets. A reliable and robust sensor system is crucial for an effective SHM. Fiber optic sensors (FOS) offer many advantages over other contemporary sensors such as strain gauges, piezo sensors etc. However, FOS has yet not been widely used or well developed for offshore industry. This paper discusses the SHM applications of fiber optic sensors (FOS) for offshore structures. The capabilities of Fiber Bragg grating (FBG) and Brillouin optical time domain reflectometry (BOTDR) sensors are investigated in this research project. Since the structures operate in a very harsh environment, robustness and repeatability of the sensors matter the most here. Though the repeatability of FBG sensors is very good, the fiber itself is easily breakable. In this paper, various protection schemes for FBG sensors and their performance in static and dynamic loading tests are discussed. Finally, a protection scheme with which the FBG sensors have high repeatability and robustness is suggested for offshore SHM applications.
