Engine maker Everllence has signed a framework agreement with Dutch shipbuilder Damen Shipyards Group for the serial supply of its 175D high-speed engine, with the deal centred on Damen’s fuel-flexible tug programme.

The agreement, announced on 7 September, establishes a long-term supply relationship between the two companies. According to Everllence, the arrangement extends beyond the tug programme to cover other applications, with delivery of engines expected to continue well into the future.

Damen, which describes itself as the world’s largest producer of harbour and escort tugs built to a standard, predefined design on a serial basis, says this production model is intended to reduce vessel delivery times for tug operators. The company’s fuel-flexible tug portfolio is aimed at operators seeking to maintain current competitiveness while preparing for anticipated changes in fuel options and regulations.

The 175D engine is said to support Damen’s fuel strategy through its modular design. According to Everllence, the engine is compatible with diesel operation and 100% biofuel today, and can be configured — either as a new build or through retrofit — for dual-fuel methanol operation in the future.

Erik van Schaik, Product Manager Tugs at Damen, commented: “For our next generation of fuel-flexible tugs, Damen selected Everllence’s 175D engine because it offers the right combination of compact power density, proven performance, and availability within the required development timeline. This choice supports our ambition to bring future-ready tug designs to market quickly, while continuing to value the strong relationships we have built with our engine partners across our wider portfolio.”

Ben Andres, Vice President and Head of Medium & High-Speed Four-Stroke Marine at Everllence, remarked: “The signing of this framework agreement with Damen represents an important strategic step for Everllence and establishes a long-term collaboration with one of the world’s leading builders of harbour and escort tugs. It highlights the industry’s increasing demand for propulsion solutions that combine proven performance with a clear pathway towards alternative fuels. Together with Damen, we are enabling operators to invest in vessels that meet today’s requirements while being prepared for the fuel landscape of tomorrow.”
