WinGD, CMB.TECH sign four-way deal to develop ammonia-fuelled marine engines for bulkers

Swiss marine power company WinGD on Tuesday (5 December) said it has concluded a four-party agreement underwriting Belgian bulk carrier operator CMB.TECH’s order of X72DF-A ammonia-fuelled engines.

CSSC Qingdao Beihai Shipbuilding (QBS) and engine builder CSSC Engine Co (CSE) were the other signatories in the joint undertaking to power a series of 210,000 DWT bulk carriers to be delivered from Qingdao through 2025 and 2026.

Following confirmation of the engine order, the agreement advances the project between WinGD and CMB.TECH announced in January to develop the 72-bore ammonia-engine. The close cooperation and shared responsibility reflected in the agreement highlights the groundbreaking nature of the order: the vessels will be the first ammonia-fuelled bulk carriers to be built; the WinGD engine designs will be the first of their size for ammonia; and they will be the first ammonia engines built in China.

CMB.TECH CEO, Alexander Saverys, said: “CMB.TECH sees green ammonia as one of the big solutions to decarbonise long-distance shipping and this order brings to fruition our active commitment to develop this pathway. The gathering of expertise under this agreement will ensure that our first ammonia-fuelled vessels are built and powered in a safe and sustainable way, as well as helping to decarbonise our business and our customers’ logistics.”

WinGD CEO, Dominik Schneiter, said: “Having progressed the engine design and vessel integration concept rapidly with CMB.TECH over the past nine months, enlisting the mutual cooperation of the shipyard and engine builder is a critical next step. As well as safeguarding the successful entry into operation of these innovative engines, this collaboration will also accelerate the spread of ammonia capabilities across key stakeholder groups, placing the whole industry on surer footing as it explores a vital decarbonisation pathway.”

QBS Executive VP, Gu Kechao, said: “CMB.TECH’s decision to have its first ammonia-fuelled vessels built by CSSC Qingdao Beihai Shipbuilding underscores the company’s faith in the quality and value of our work. It also highlights growing acknowledgement of the wider Chinese capability in complex shipbuilding projects. Building among the first ammonia-fuelled vessels in the world will place QBS in a strong position to support further customers with their maritime decarbonisation projects.”

CSE Chief Engineer, Zhang Guangwei, said: “Bringing a new engine design into commercial operation is always the result of strong joint effort between engine and vessel designer, engine builder, shipyard and owner. CSE is honoured to be the first engine builder in China to deliver ammonia-fuelled engines to the maritime market, and to take an early role in what will become a significant market as ammonia fuel is used more widely in shipping.”

WinGD’s X-DF-A engines operate using high-pressure fuel injection with a small portion of pilot fuel, and will have performance and fuel efficiency comparable to the company’s diesel-fuelled X-Engines. No aftertreatment is required for N2O emissions, while selective catalytic reduction is used to ensure Tier III NOx compliance in both ammonia and diesel modes.

Safe operation and maintenance of ammonia-fuelled engines and vessels has been a key undertaking of the project to date. The hazard identification (HAZID) studies, followed by an Approval in Principle from Lloyd’s Register of the X-DF-A engine concept were pivotal to WinGD and CMB.TECH verifying that ammonia-fuelled engines built, commissioned and operated to the approved design have equivalent safety to conventionally fuelled engines.

Mitsui E&S commercialises ammonia dual-fuel engines and fuel supply systems

Mitsui E&S on Thursday (20 August) said it has completed the commercialisation of large ammonia dual-fuel marine engines and ammonia fuel supply systems (AFSS).

As the only company in Japan manufacturing both ammonia dual fuel engines and AFSS, the company said it has established a supply framework for marine propulsion systems aimed at the practical implementation of ammonia-fuelled vessels.

“While ammonia holds promise as a next-generation fuel that emits no carbon dioxide during combustion, it is difficult to ignite and poses risks related to toxicity and corrosiveness; therefore, ensuring safety, reliability, and environmental performance is crucial for its practical implementation in society,” it said.

In February, Mitsui E&S conducted land-based tests involving the integrated operation of the Ammonia dual fuel engine MITSUI-Everllence B&W 7S60ME-C10.5-LGIA-HPSCR and the AFSS, witnessed by ClassNK (Nippon Kaiji Kyokai), and verified their performance.

Following the completion of the tests and the subsequent review, Mitsui E&S confirmed the completion of onshore testing in accordance with classification society rules and verified compliance with International Maritime Organization (IMO) NOx regulations through NOx certification.

“Consequently, we have finalised the commercialisation of the ammonia dual fuel engines and the AFSS and are now able to supply it for actual vessels,” it added.

Mitsui E&S said it has already decided to expand its land-based testing facilities for AFSS compatible with both Everllence and WinGD licensed engines.

“In conjunction with this, we will establish a mass-production system for both the engines and the AFSS to meet the anticipated rise in demand,” it said.

Mitsui E&S added the company is expanding its engine lineup to accommodate a diverse range of next-generation marine fuels, including ammonia, by offering ammonia-fuelled engines and AFSS as an integrated package.
