LNG carrier cargo containment system monitoring Client Exxon Mobil Challenge To develop a ?breoptic condition monitoring system for the cargo containment system of Qmax LNG Carriers Resolution A variant of the SmartCell FBG pressure transducer was developed that was suited to welding within the containment system primary membrane and measurement of the dynamic pressure associated with the cryogenic liquid sloshing during vessel motion. Prototype sensors were manufactured and tested for their dynamic pressure response. Quali?cation of the welding of the sensors into the primary membrane was carried out. A method of measuring the dynamic compression of the secondary containment system at low temperatures caused by sloshing impacts was developed. Quali?cation of the measurement was car
