NYK to head consortium for converting LNG engines to high-efficiency technology

NYK has received approval to convert a LNG carrier’s steam turbine to a dual-fuel diesel engine, marking the first time Class NK has granted such approval for main engine conversion on LNG carriers. The goal is to improve environmental performance, make efficient use of existing vessels, and contribute to the stable transport of LNG. With the growing demand for LNG transport and the retirement of steam turbine-powered LNG carriers, the shortage of LNG carriers is a concern.

To address this issue, the three companies involved will replace the main propulsion of steam turbine-driven LNG carriers with low-speed, dual-fuel diesel engines called X-DF engines. This engine replacement aims to improve fuel economy and contribute to the efficient use of the ship’s resources, while also supporting the stable transport of LNG. The companies are leveraging the technical capabilities of Japan’s maritime group to achieve these goals.
