Proposal for Semi-permanent Extension of Engine Overhaul Interval Using Technology for Semi-permanent Use of Marine Engines and Lube Oil

Abstract

We have successfully developed a technology of semi-permanent use of engines and near zero waste oil with almost no wear and near constant thermal efficiency, with remarkable reduction in engine trouble and parts replacement. The results were verified through ship tests 8 years (33,000h). The technology has been in practical use in many marine and diesel generator engines. Also, we presented our theory and technology for the integration of various lube oils ideally with a TBN close to zero. Empirical tests have started in June 2014 and are on-going. Based on the results, we propose a semi-permanent extension of TBO (Time Between Overhaul) by establishing a monitoring system that indicates whether an overhaul is really required or not.
