The oil purifier has always been one of the most essential auxiliary machines for marine use, employed for purifying the fuel oil and lubricating oil for the main engine and the diesel engine for generator primarily.<BR>As a result of changes in the demand for various petroleum products in recent years and the advances in oil refinery technology for adaptation to such changes, low-grade heavy fuel oil is now used, which has high vicosity and high density.<BR>The sludge content of the fuel oil is rather high, and it contains FCC catalyst, and various other problems are also encountered. All these must be overcome not only by special provision in the engine design but also by a new fuel oil treatment system including an oil purifier and other fuel oil treatment devices.<BR>On the other hand, navigation with a small-size crew for better economy, typified by the“pioneer ship plan”in Japan, seems to be the order of the day, and that calls for higher reliability and a maintenance work saving.<BR>Taking these conditions into account, this paper will focus attention on“countermeasure to change of enviroment on oil purifier”, which have been recently developed.
