MAN ES announces MAN 175D methanol dual-fuel engine will be available by 2026

MAN Energy Solutions on Monday (27 November) announced that a dual-fuel version of its MAN 175D high-speed engine, capable of operating on methanol, will be available by the end of 2026. 

The new variant, designated MAN 175DF-M, will be available both as newbuild and retrofit variants.

MAN Energy Solutions states that the 175DF-M will be optimised for diesel-mechanical and diesel-electric propulsion to achieve the largest methanol share and best efficiency for various applications and load profiles. In fact, the engine has already been awarded the ‘fuel ready’ certificate by DNV, guaranteeing the introduction of this dual-fuel methanol technology.

“The 175D engine is MAN Energy Solutions’ latest addition to the high-speed maritime sector and is, as such, one of the pillars of its efforts to develop a methanol-ready engine portfolio as the demand for such technology has rapidly been increasing of late,” the firm said in a statement.

With its success in achieving series-approval for its two-stroke engines, MAN Energy Solutions said it has used this experience to develop an optimised solution for its four-stroke engines, including successful single-cylinder testing. As such, the results of these efforts will fuel the upcoming development and validation of the dual-fuel PFI (Port Fuel Injection) technology for its methanol-ready 175D engine.

Florian Keiler, Head of High Speed, MAN Energy Solutions, said: “The MAN 175D has proven to be very competitive in terms of sustainability and efficiency with the lowest fuel consumption, lowest lube-oil consumption and longest overhaul times in its class, minimising its environmental footprint. In terms of future fuels, the next logical step, apart from being able to run on 100% bio-fuels, is to ensure methanol combustion.”

“Based on numerous exchanges with customers, we came to the conclusion that the dual-fuel principle, reliability, efficiency, a high methanol share, competitive life-cycle costs and maximum achievable output were key requirements for the 175DF-M’s development. Therefore, after conscientious investigation and consideration, we settled upon the PFI combustion technology as the most favourable. Fundamental combustion development will start in 2024, leading up to a first field-test of the methanol engine in 2026. The MAN 175DF-M engine will subsequently be ready for sales release at the end of 2026.”

MAN Energy Solutions believes that PFI is the most advanced technology currently available. Its development targets a highest methanol share over a wide power range while achieving the highest cylinder output in its high-speed engine class. In particular, optimisation for diesel-electric multi-engine plants will allow operation of the engines at an optimal load point achieving the highest methanol share. As result, when using biofuels, the MAN 175DF-M’s carbon footprint will be reduced to zero while retaining full fuel-flexibility for operation anywhere in the world.

ExxonMobil on Friday (7 June) said its advanced 40BN cylinder oil, Mobilgard™ 540 AC, has been validated by WinGD for use in its dual fuel marine engines with conventional fuels, including methanol, and now LNG. 

The high performance cylinder oil, which also has an approval from MAN ES for use in its two-stroke engines, was developed for use in slow-speed, two-stroke marine engines operating on fuels with up to 0.50% sulphur content, LNG, ethane, methanol and LPG.

Mobilgard 540 AC has demonstrated an excellent ability to keep the engine clean while running in gas mode at optimised low feed rates. The oil is also suitable for methanol operation and with other liquid fuels up to 1.5% sulphur levels. 

This comes in addition to the existing MAN ES Category II approval, positioning the oil as a supreme oil in the two stroke marine engine space.

“Vessel operators need reliable, high performance solutions, now more than ever,” explained Yannis Chatzakis, Global Technology Program Manager at ExxonMobil. 

“This double validation underscores ExxonMobil’s commitment to delivering both. As with all our cylinder oils, Mobilgard 540 AC has been developed using our balanced formulation approach. This helps ensure outstanding protection at optimum feed rates, supporting the peace of mind our customers need.”

Used in conjunction with a next generation scrape-down oil analysis service, such as Mobil℠ Cylinder Condition Monitoring, the cylinder oil can help:

  • Deliver exceptional cleanliness with low-sulphur fuel due to high level of detergenc
  • Combat deposits and scuffing-related engine wear associated with low-sulphur fuels
  • Ensure performance even in severe operating conditions as a result of excellent thermal and oxidative stability

The firm added Mobilgard 540 AC has demonstrated the ability to deliver these benefits while optimising cylinder oil feed-rates and effectively managing acid neutralisation in a range of engines and fuel applications. 

The cylinder oil has already been granted Category II status by MAN ES for use in its two stroke marine diesel engines; the addition of the dual fuel validation from WinGD positions the oil as one of the highest performing in the market.

“ExxonMobil continues to work with stakeholders, including engine OEMs, from across the marine industry as we believe that this offers the best results for our customers and the wider maritime sector,” said Chatzakis.

“The next few years are likely to throw up new challenges as we collectively pursue a lower emissions future. Our commitment to innovation will help achieve that goal.”

Note: Mobilgard 540 AC is available in all major ports. Full details can be found in its Ports & Services Guide - www.exxonmobilportsandservices.com

WinGD, Alfa Laval, ABS and K Shipbuilding to develop ammonia-fuelled tanker design

Swiss marine power company WinGD on Thursday (6 June) said it will work together with Swedish marine technology leader Alfa Laval and the American Bureau of Shipping (ABS) and Korean shipbuilder K Shipbuilding (KSB) on the development of an ammonia-fuelled MR tanker design, under a memorandum of understanding signed in April, which will feature a 6X52DF‑A engine from WinGD.

WinGD will work with KSB to deliver fuel gas system specifications suitable for the vessel application and the selected engine, while Alfa Laval will deliver the detailed documentation for the final fuel gas system design. The design will be reviewed by ABS, with the aim of issuing an approval in principle.

WinGD Vice President R&D, Sebastian Hensel, said: “After early orders for bulk carriers and ammonia carriers, it is encouraging to see that ammonia-fuelled tanker projects are picking up momentum.”

“And even more encouraging that our X‑DF‑A engines are at the heart of many of these projects. Developing full vessel designs that shipowners can adopt easily will only accelerate the transition and we are pleased to be part of the collaboration with KSB in delivering this design.”

Head of Marine Separation & Fuel Supply Systems, Viktor Friberg, Alfa Laval, said: “This MOU signifies a powerful step forward to make ammonia a viable marine fuel. Our proven expertise in handling diverse fuel types, especially methanol and LPG, will be instrumental in designing the new fuel supply system for ammonia.”

“We believe that partnerships are key for the maritime industry to achieve the ambitious decarbonisation targets and support the fuel transition. By working alongside WinGD, ABS and K Shipbuilding, we accelerate this transition and make it safer.”

The X52DF‑A engine is the smallest bore size available in WinGD’s ammonia-fuelled X‑DF‑A series, and the first to be developed. It is expected to have wide application across bulk carriers, tankers and ammonia carriers, and has already been ordered for two ammonia carriers to be delivered in early 2026. 

The X52DF‑A is also the engine design on which four class societies to date, including ABS, have issued approvals in principle for the X‑DF‑A series, assuring shipowners that the engine can be deployed in operation safely.

JDPs and other cooperations have been a cornerstone of WinGD’s ammonia engine developments, with several industry partnerships focused on vessel designs and crew training – supporting both the deployment of ammonia-fuelled engines and the preparedness of the maritime industry to operate them safely
