Fiber Optic Strain Sensors (FOSS) to Monitor Strains on a Navy Vessel During Operations

Abstract

This document summarizes the recent deployment of a fiber optic strain sensing (FOSS) system to monitor loads on a Navy Vessel, as requested and authorized by Commander Naval Surface Force, Atlantic. The objectives were to (1) conduct an in-service validation of the technology onboard a U.S. Navy ship and (2) determine contributing influences to recurring cracking of [new] deckplate, as described by the Southeast Regional Maintenance Center (SERMC) Port Engineer. Previous NAVSEA investigations discuss sensitization of the aluminum and onset of stress corrosion cracking (SCC), although the source of the SCC stresses have never been characterized. This effort attempts to quantify performance of the FOSS technology as a tool to provide such characterization. Covered in this document are the instrumentation, data collection and subsequent analysis.
