Abstract
AbstractShips and offshore structures are exposed to wave and engine excitation loadings during navigation and cargo/ballasting operations. These excessive loads may cause damages to hull and may result loss of life the ship. Therefore, it is important to develop a system that allow accurate measurements of global hull loads. The objective of the study is developing a fiber optic monitoring system that is capable of monitoring, recording and warning of the vessel performance. A method for measurement of global loads on a vessel, using strain measurements from a network of fiber optic strain sensors and extensive finite-element analyses(FEA) with idealistic load cases, is presented. The method has been successfully validated on the idealized ship structure model with strain sensors.※Keywords: Hull monitoring system(선체 모니터링 시스템), Fiber optic sen sor(광섬유센서), Strain measurement(변형률 측정), Measurement of global load(글로벌 하중의 측정) 1. 서론 선박 및 해양구조물은 시간에 따라 변동하는 파랑 외력과 같은 피로하중에 노출되어 있으며 이러 접수일: 2007년 10월 1일, 승인일: 2008년 2월 12일✝교신저자, Kimm@pusan.ac.kr, 051-510-2486
