Energy Integrity and Power Solutions Limited (EIPS): Unmatched Reliability for Yanmar Marine Engines
Japanese Precision, Global Endurance
Yanmar has been a pioneer in diesel technology since 1912, consistently setting the world standard for fuel efficiency and compact power. Known for their “fuel-sipping” performance and incredible longevity, Yanmar engines are the heart of the global workboat fleet. From the smallest fishing vessel to the largest ocean-going tug, Yanmar provides the steady, reliable power that the maritime industry depends on.
At Energy Integrity and Power Solutions Limited (EIPS), we bring technical integrity to your Yanmar maintenance strategy. We specialize in providing high-quality spare parts and technical support that honor Yanmar’s legendary engineering, ensuring your engines run cleaner, longer, and more efficiently.
Our Technical Scope: The Yanmar Portfolio
EIPS maintains a robust supply chain and technical database for both Yanmar’s high-speed commercial engines and their heavy-duty medium-speed power plants.
- Medium-Speed Main & Auxiliary (EY & N Series)
The EY and N series are the “workhorses” of the commercial sector, widely used as both main propulsion for tugs and coastal tankers and as reliable auxiliary gen-sets for larger vessels.
- Yanmar EY Series (6EY18, 6EY22, 6EY26, 8EY26): Celebrated for low life-cycle costs and high reliability. The 6EY22 is a particular favorite in the West African maritime industry for its durability in harsh conditions.
- Yanmar N Series (N18, N21, N330): Traditional, robust designs that have powered the merchant fleet for decades.
- High-Speed Commercial (AYM & LY Series)
Specifically designed for the workboat, tug, and fast ferry markets, these engines provide massive torque and rapid response.
- Yanmar 6AYM & 12AYM: The industry standard for heavy-duty workboats. The 12AYM-WGT provides up to 1,822 mhp, delivering the bollard pull required for demanding towing operations.
- Yanmar 6CXM & 6LY Series: Compact, high-performance engines ideal for pilot boats, patrol craft, and fast passenger ferries.
- Smaller Workboat & Lifeboat Engines
- Yanmar JH, 4LHA, and 6LP: Reliable, lightweight power for lifeboats, tenders, and small commercial craft.
