Who we are
- A truly global team, with 28 members from 14 different countries (Japan, the USA and all over Europe).
- Experts from all relevant disciplines – ship operators, engine and equipment manufacturers, oil and additive suppliers, classification societies and scientific institutions.
- To define common industry positions for the use and maintenance of lubricating oils in different types of engine.
What we do
- The WG works to promulgate know-how about marine lubrication (including power plant applications) by producing guidelines and recommendations dedicated to deepen our understanding of this important subject.
- Activity centers for complementing inherent engine design reliability with an adequate periphery regarding the use of appropriate lubricants and fuels.
- Preparation in subgroups on issues to be discussed and endorsed by the entire Working Group during its meetings.
Our current projects and activities
- Future fuel scenarios and their impact on lubrication.
- Interaction between lubricants and emission control measures (e. g. SCR).
- Update of the CIMAC recommendation on the lubrication of two-stroke crosshead diesel engine (publication currently planned for the end of 2013).
- Guideline "The causes of scuffing and actions to prevent scuffing in two-stroke engines" (March 2023)
- Guideline 'Used engine oil analysis' [PDF] (February 2023)
- Guideline 'On the Lubrication of Reciprocating Gas Engines' [PDF] (March 2021)
- Guideline on 'Two Stroke Engine Cold Corrosion' [PDF] (November 2017)
- CIMAC Recommendation 31 - 'The Lubrication of Two-Stroke Crosshead Diesel Engine’ by CIMAC WG8 ‘Marine Lubricants' [PDF] (March 2018)
- Guideline on future fuel scenarios and their impact on lubrication [PDF] (May 2014, withdrawn)
- Guideline on the relevance of Lubricant Flash Point in Connection with Crankcase Explosions [PDF] (July 2013)
- Two meetings are held each year, each one hosted by one of the members.
- Typically 20 – 25 members participate at each meeting.
