Predicting crack formation in gas combustion units on LNG carriers
A data signature that predicts cracks in the GCU cooling jacket, alerting crew before the most common failure: USD 200–300 thousand a year in repair and maintenance savings.
Challenge
Gas combustion units across an LNG fleet were breaking down more often than expected. A working GCU is mandatory on an LNG vessel, so a failure at the wrong moment means off-hire.
Solution
Analysis found a tell-tale data signature preceding crack formation in the GCU cooling jacket, the most common failure mode. An analytical model running on the sensor data alerts the vessel crew when the signature occurs, so they can take preventive measures.
Impact
USD 200–300 thousand a year in estimated repair and maintenance savings, and lower off-hire risk.
