The AiP for the X-DF-A engine range is expected to provide shipowners with the confidence to develop vessel designs based on ammonia propulsion, the classification society said.
WinGD’s first engine, the 52-bore X52DF-A unit, will be available for delivery in the last quarter of 2024. It is suitable for a range of ships including bulk carriers and gas tankers.
“Time is of the essence as shipping looks to clean power solutions,” declared Dominik Schneiter, WinGD CEO. “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.”
LR’s Nick Brown, CEO, commented: “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. LR is delighted to have worked with WinGD on this groundbreaking development.”
The AiP means that WinGD has satisfied LR experts that the X52DF-A concept is technically ready to satisfy future regulatory requirements with no major obstacles. During the AiP analysis, the classification society’s team assessed engine safety, risks relating to ammonia as fuel, and preliminary engine and fuel supply system design. They also considered the compatibility of materials with ammonia fuel
