This article summarizes the findings of a Det norske Veritas project to investigate experience with inert gas systems for ships carrying hazardous petroleum cargoes. An analysis of failure reports from 53 ships has shown that the components most susceptible to damage are the gas blowers, scrubbers and effluent lines. The corrosion resistance of various materials used for scrubber construction is compared for flue gas based inert gas systems on both turbine- and Diesel-powered ships. It is considered that a normal steel with a synthetic rubber, epoxy or polyester coating gives the best performance. The statistics for damage to blowers show that this occurs most frequently in bearings, impellers and shafts of systems where there has been carry-over of water from the scrubber.
