Longitudinal ship´s hull strength monitoring with optical fiber sensors

Longitudinal ship´s hull strength is the most fundamental strength of a ship structure, and many research works have been done from this aspect. In this paper we aim to obtain a possibility to determine hull girder strength using optical fiber sensors. Collected data can be used as handy to verification of transverse, longitudinal and local strength for a momentary loading condition and to help make timely decisions in the event of an emergency which has been arising from accident. The ship´s strength analysis is listed. The longitudinal strength distributions are described in a detail. Real time monitoring ship´s hull with optical fiber sensors is proposed.
