Meet performance targets and industry regulations

It is vital your vessels keep delivering value for as long as possible. As they age, it becomes more important to maintain and optimize performance – not only to maximize efficiency and minimize downtime, but to comply with ever tightening environmental regulations.

Our portfolio of retrofit solutions for propellers, small bore engines, and propulsion systems are some of the most effective ways to extend the lifetime of your vessel and future-proof its performance. With short installation times that can be completed during normal overhauls or dockings, you can reduce emissions, save fuel and lube oil, lower maintenance costs, and meet industry requirements, including CII.
