Severe contamination of the forced-lubrication system of a propulsion turbine can result in a ship being out of service for several weeks. Though sea water is the most harmful of the contaminants that can enter the system, solid matter can also cause serious trouble. The Author (of the Indian Navy) discusses both classes of contaminants and their causes and effects, and suggests methods for the prevention (as far as possible) and cure of such contamination. It is mentioned that attempts to devise a much improved procedure for the internal cleaning of the system have failed. It is recommended that a contaminant-detection device should be incorporated in lubrication systems (in existing as well as in future ships); the tanks should have an epoxy resin coating; and the system should have a self-cleaning automatic separator. Future improvements should include the provision of a contamination early-warning system; tanks and piping should be made from a transparent plastic material; and remote-reading contents-gauges should be fitted instead of soundingtubes. In the interest of minimising both production and maintenance costs, optimum contamination limits should be determined. Some suggestions are made for the further investigation of these contamination problems. Order from BSRA as No. 49,663.
