T1 - Investigation of the fiber-optic strain sensors' beahvior under offshore conditions to create standards for reliable application N2 - The application of fiber-optic sensors in offshore environment is a big challenge. Especially if sensors have to be installed in the tidal zone and components are exposed to extreme environmental attacks as well as mechanical loads. There are no sufficient experience on how to test selected materials, how to handle application and how remotely to assess the function of installed sensors operating several decades during summer and winter time. It has to be feared that installed sensor components could be damaged in case of heavy storms and strong waves or due to ice drift. Another danger is the biological attack to sensors. Not only the high amount of salt and UV radiation could degrade the protecting materials of sensor systems, it is well-known that sea biological influences such as barnacles and other types of fouling perturb the proper function of sensors or even lead to failure. In Germany, a research project is being carried out to investigate the specific offshore influences to fiber-optic sensor systems with the objective to develop evaluation strategies and corresponding testing procedures and standards. The paper describes first results after harsh test cycles and gives first bullets for a corresponding standard for application in offshore environment.
