WinGD will deliver ammonia engines by ‘25

WinGD has disclosed ammonia fuel technology developments involving two shipowners

WinGD said it is on track to deliver its first X-DF-A dual-fuel ammonia engines by the first quarter of 2025, with the first X-DF-A powered vessels in service starting in 2026.

The confirmation follows combustion tests at WinGD research facilities in December 2022. The company said it has received “concrete orders” for the engines and has seen recent rapid progress in developing an engine concept capable of using the zero-carbon fuel efficiently, safely and reliably.

WinGD has disclosed ammonia fuel technology developments involving two shipowners. Last month it signed an agreement with AET Tankers and sister company Akademi Laut Malaysia to develop crew training on ammonia engines. In January 2023 it announced a partnership with CMB.Tech, a sister company of Belgian shipowner CMB, to develop ammonia-fuelled engines for ten 210,000 DWT bulk carriers.

The Swiss marine power company said it is collaborating with engine and shipbuilders in China, Japan and Korea, and has done its own extensive investment in research. Most recently, in June WinGD signed a memorandum of understanding with Mitsubishi Shipbuilding Co. Ltd to prepare X-DF-A for application across a range of vessel sizes and for integration with the engine builder’s ammonia fuel supply system. This follows a development project with Hyundai Heavy Industries initiated in June 2022.

WinGD recently reported how a unique validation platform housed in its Engine Research & Innovation Centre (ERIC) in Winterthur, the Spray Combustion Chamber (SCC), had enabled rapid development of 2-stroke combustion concepts and emission models. Since first ignition in 2022, the team has gained a wealth of insights into the combustion and emission characteristics which form the basis for a rapid deployment of the technology to the portfolio, the company said. WinGD can now provide accurate figures for ammonia consumption and relevant emissions.

Tests on the unique, purpose-built single-cylinder engine located at ERIC Winterthur and a multi-cylinder test engine at WinGD’s Global Test Centre in Shanghai will commence, in collaboration with China Shipbuilding Power Engineering Institute Co. Ltd (CSPI).

Across the multiple collaborations and further work with class societies, ammonia fuel supply system suppliers and shipyards, WinGD has focused on defining safety aspects related to the engine installation and ammonia supply system. WinGD has recently published the guidance and installation documentation for its X-DF-A engines across a range of bore sizes, available here.

“For the industry to be truly ready for alternative fuels, the engine concepts that use them – and the vessel designs, auxiliary systems, crew training and field support network - need to be ready before the fuels become widely available,” said WinGD CEO Dominik Schneiter. “Our development timeframe, as evidenced by these milestones in research and collaboration, shows that we are on track to give shipowners and operators the time they need to prepare for decarbonized ship power using ammonia as fuel.”
