Wärtsilä has developed a radical de-rating solution for customers operating larger container vessels that offers substantial reductions in fuel consumption and greenhouse gas emissions.

The solution has initially been developed for RT-flex96C-B engines, and will see the engine converted to a 72-bore engine.

Sangram Nanda, General Manager of Technology Development at Wärtsilä 2-Stroke Services in Switzerland, explained that the Fit4Power solution had been developed in record time in response to specific customer requests to improve the CII profile of larger container vessels.
