WinGD Makes History With Ammonia Two-Stroke Engine Approval


Swiss firm WinGD’s ammonia-fueled two-stroke engines just got their first-ever Approval in Principle (AiP) from Lloyd’s Register. This is a game-changer for shipowners considering greener tech in future vessel designs.

X52DF-A Engine: Ammonia-Powered

The 52-bore X52DF-A engine, the first in WinGD’s ammonia-fuelled series, is slated for delivery from the fourth quarter of 2024. It is designed to be versatile, suitable for a variety of vessels, including gas and bulk carriers.

Dominik Schneiter, CEO of WinGD, underscored the urgency of transitioning to cleaner power solutions. “This approval shows the industry that WinGD is leading the way in bringing carbon-free ammonia power to the deep-sea fleet. With the support of expert partners including Lloyd’s Register, these technologies will be available long before emission targets require them, giving operators vital space to plan and gain experience,” he said.

Lloyd’s Register CEO On Trust

Nick Brown, CEO of Lloyd’s Register, emphasised the importance of trust in new technologies. “The maritime industry needs to trust that new technologies can be deployed safely as it continues to evaluate multiple transition pathways. This AiP will give first movers confidence that, subject to subsequent care in design, build, integration and operation, this ammonia two-stroke engine can help meet that demand,” he stated.

During the AiP process, Lloyd’s Register assessed various aspects including the engine safety concept, risk assessments, and preliminary engine and fuel supply system design. It also confirmed the compatibility of materials with ammonia fuel.

WinGD plans to extend its ammonia-fuelled engine series, launching a 72-bore variant in 2025 and other engine sizes in 2026, based on market demand. These engines will operate according to the Diesel principle in both diesel and ammonia modes and will have the same rating field as WinGD’s existing Diesel engines. They will also be available with the same cylinder configurations, offering a broad spectrum of options for various vessel types, from small tankers and car carriers to very large tankers.
