Although the principles of marine bearing design and lubrication are generally understood and do not change very much from year to year, failures are still too numerous. It is felt that reliability could be improved by paying greater attention to detail during the design, manufacture and installation stages of the individual equipments and also during the stages of the overall design and installation of the whole propulsion line. All these stages must be closely integrated with the lubricating system. The paper gives an account of problems over recent years associated with main propulsion system bearings. The design and installation of lubricating oil systems is discussed in relation to the requirements of the bearings. The paper attempts to collate Ministry of Defence (Navy) experience over recent years, to illustrate some of the reasons for failure and the lessons to be learnt. Reference is made to test work carried out as a design/development intention and also to special investigations that have been carried out as a result of specific failures in service. Some indication is given as to the changes which may take place in the future and changes in machinery installation which are likely to require new techniques.
