Ship and offshore structures may be exposed to enormous hull stress, fatigue and so on during navigation and cargo/ballasting operations. These excessive loads may cause damages to hull and sometimes result even total loss of the ship and loss of life. Therefore, it is important to develop a ship structure health monitoring system. Use of fiber optic sensor technique appears to be very appropriate in application to monitoring the safety of ship structures such as hull girder, cargo holds and oil tanks, etc. The fiber optic sensor can analyze strain distribution as well as possible defects in the structure without disassembling. The initial experimental results obtained in this study indicate that the fiber bragg grating(FBG) sensors can provide reliable strain measurements during tensile test. The fiber optic sensor showed more precise strain measurement with a close agreement with strain gage measurement.
