New ultra-low emissions Wärtsilä 31DF cuts methane slip

Wärtsilä has introduced a new ultra-low emissions version of its Wärtsilä 31DF engine, first introduced in 2015. When operating on LNG, this new version of the dual fuel engine can further reduce methane emissions on a 50% load point by up to 56% and nitrogen oxide (NOx) emissions by up to 86%. On a weighted average, the engine’s new technology can reduce methane emissions by 41% more than the standard Wärtsilä 31DF engine, which is claimed to already have the lowest emission levels on the...

FERRIES 2023: Renewable diesel as a ferry decarbonization tool

At FERRIES conferences, we talk a lot about various fuel options for ferry operations. One fuel for ferries that we haven’t explored in detail—at least not lately—is renewable diesel.

At FERRIES 2023, taking place November 14-15 in Jersey City, N.J., just across the harbor from New York City, Neste U.S. Vice President of Renewable Road Transportation Carrie Song will discuss how renewable diesel (RD) is being used as a decarbonization tool in the ferry industry and how its customer, Hornblower,...

ClassNK issues AiP for ship powered by hydrogen-fueled two-stroke

AiP award ceremony for ship powered by hydrogen-fueled two stroke

In a world first, ClassNK has issued an Approval in Principle (AiP) for a ship equipped with a large low-speed, hydrogen-fueled two-stroke engine as the main propulsion engine. The parcel layout concept granted the AiP was developed by Mitsui O.S.K. Lines, Ltd. (MOL), MOL Drybulk Ltd. (MOL Drybulk), Onomichi Dockyard Co., Ltd., Kawasaki Heavy Industries, Ltd. and Japan Engine Corporation (J-Eng).

Demonstration operations of the 17,500 dwt vessel are targeted to be conducted for two years from...

VIDEO: Maersk undocks first 16,000 TEU methanol-fueled containership

Maersk has released video showing the float out at Hyundai Heavy Industries of the first of its new series of 16,000 TEU methanol-fueled containerships. At the time it unveiled the design it said that it allows a 20% improved energy efficiency per transported container, when comparing to the industry average for vessels in this size.

The undocking comes within weeks of another Maersk methanol milestone, the christening of the world’s first methanol-fueled containership, the 2,136 TEU feeder ship

MAN methanol gensets picked for first methanol fueled car carriers

methanol genset image

Methanol as a marine fuel is now moving into the car carrier sector. The first two methanol fueled vessels ordered for the sector —two 9,300 CEU (car equivalent unit) pure car and truck carriers on order at China Merchants Heavy Industry (CMHI) for China Merchants Energy Shipping — will be the first vessels fitted with MAN Energy Solutions’ M 21/31 DF-M methanol gensets.

Main propulsion power in each PCTC will be by an MAN B&W 7S60ME-LGIM (-liquid gas injection methanol) main engine and each...

WinGD wins LR approval in principle for ammonia-fueled two-stroke engines

As the race to be first to market with future-fueled engines picks up pace, Lloyd’s Register has granted Winterthur, Switzerland, headquartered engine designer WinGD the first ever approval in principle (AiP) for its ammonia-fueled two­­‑stroke engines. The AiP was awarded for WinGD’s X-DF-A dual-fuel range and gives shipowners the assurances they need to realize vessel designs using ammonia-fueled main engines.

WinGD says that its ammonia-fueled two-stroke engine series research has been...

ABS and Asiatic Lloyd eye ultramax conversion to methanol fueling

In yet another sign of the growing interest in methanol as a marine fuel, ABS and Asiatic Lloyd Maritime LLP, a member of the AL Group, have signed a joint development project (JDP) to study the feasibility of converting the fuel system of an ultramax bulk carrier, from conventional diesel to methanol.

The study is focused on a series of up to eight ABS classed ultramax bulk carriers ordered for construction in the New Hantong Shipyard, China, for AL Group.

“Converting vessel propulsion systems...

MAN in MoU on methanol retrofits

MAN Energy Solutions has signed a Memorandum of Understanding (MoU) with Stena Teknik – Stena’s inhouse R&D division – and Proman – the world’s second largest methanol producer. The agreement will see the parties cooperate on a project to retrofit MAN 48/60 engines to make them capable of dual-fuel, diesel and methanol operation. Stena and Proman announced a partnership to develop a methanol retrofit and fuel-supply solution last year.

Stefan Eefting, head of PrimeServ Germany, and Bernd...
