From Wärtsilä

The Two-Stroke Future Fuels Conversion platform will be conducted during the first quarter of 2022, recently revealed by Wärtsilä.

The engine combustion technology platform will enable the fast and cost-effective conversion of two-stroke main engines to operate on clean-burning future fuels, according to Wärtsilä.

LNG is widely used in these years as a marine fuel. In line with that, the development of an LNG bunkering vessel is carried out. Now the platform enables a valuable option for shipowners to avoid the off-hire charter time with an easy and comprehensive retrofit solution.

The retrofit conversion enables the vessel’s operation by the use of available LNG. The modular design also prepares for the adoption of alternative green fuels or fuel blends in the future.

The Two-Stroke Future Fuels Conversion solution is a major step to achieve the net-zero emission shipping industry. The first commercial conversion project is expected to be completed by mid-2023. The conversion concept is applicable to both large- and smaller bore engine types.

The development program has recently been concluded with successful initial engine tests in the Wärtsilä two-stroke engine laboratory in Trieste. 

The key partner in the Wärtsilä platform

Ship manager MSC Shipmanagement, part of Swiss shipping giant Mediterranean Shipping Company (MSC) has collaborated with Wärtsilä throughout the development as a key partner.

The ship manager will conduct piloting and advancement of the platform towards future fuel applications. Representatives from MSC were in attendance during some of the testing procedures. 

Roger Holm, President Marine Power & EVP Wärtsilä Corporation, said that the flexibility of the solution means that the first step towards adopting the use of future fuels can be taken now knowing that the investment will not become obsolete. He added that both economic and environmental benefits are significant.

“We have been following the development of this innovative conversion solution with high interest and we regard it as a supporting element in MSC’s journey towards net zero decarbonisation by 2050, Prabhat Jha, CEO & Group Managing Director MSC Shipmanagement, commented.

“Together with Wärtsilä we have high expectations for the next steps of this initiative, which starts with technology demonstration on one of our larger container vessels with a Wärtsilä RT-flex96C-B main engine, and which will continue to make our existing fleet ready to meet future emissions needs.”

A world-first feature of the concept is the cryogenic fuel supply system, which together with a revolutionary injection system is said to provide flexible and optimized operational performance under all conditions. Among the other notable benefits delivered by this future-proofing solution are the capability to comply with upcoming environmental regulations and therefore providing assets with an extended operational life.
