Wartsila ultra low emissions 31DF engine Wasaline

Technology group Wärtsilä on Wednesday (1 November) introduced a new ultra-low emissions version of its Wärtsilä 31DF engine. Whilst operating on liquefied natural gas (LNG), this new version can further reduce methane emissions on a 50% load point by up to 56 percent and nitrogen oxide (NOx) by up to 86%.

On a weighted average, this new technology can reduce methane emissions by 41% more than the standard Wärtsilä 31DF engine, which has already the lowest emission levels on the market.

The new version, which is applied on one of the four engines on board Wasaline’s Aurora Botnia ferry, has already helped the Finnish-Swedish ferry operator further reduce the vessel’s methane emissions by 10%.

“We are very committed to decarbonisation, and we have worked closely with Wärtsilä to make sustainable shipping a reality,” commented Peter Ståhlberg, Managing Director of Wasaline.

“It is a goal-oriented partnership that benefits both companies, as well as the industry as a whole. We have been pleased to allow the Aurora Botnia to be utilised as a floating laboratory, and we are excited to see the success of this latest Wärtsilä technology breakthrough.”

Launched in 2015, the Wärtsilä 31DF engine platform is widely recognised for its exceptional fuel economy, high performance, and minimal GHG impact. The engine, as a standard version, already meets today’s regulatory requirements. The new version will enable operators to go even further in reducing methane emissions, helping to futureproof their vessels in the longer term against potentially tightening global requirements. What’s more, improving dual fuel technology to enable methane emissions reduction will have a major impact on the long-term viability of LNG as a marine fuel.

“Our work around reducing methane slip and GHG emissions is part of Wärtsilä’s effort to continuously improve efficiency and reduce emissions of our products, and this new innovation is one more very important step along the road to decarbonisation,” commented Stefan Nysjö, Vice President of Power Supply, Wärtsilä Marine Power.

Nysjö continued: “The building of an LNG fuel infrastructure has been an important factor in shipping’s transition towards cleaner operations, and Wärtsilä continues to create solutions that support this journey. Our focus has always been to improve and optimise existing solutions, and to develop exciting new ones. With this latest introduction, we are clearly delivering on this commitment.”

Although methane slip from engines is a relatively small amount, from a percentage standpoint, it is significantly more potent than CO2 – up to 28 times greater. Across the shipping industry, cutting methane emissions is one of the most effective ways to decrease overall GHG emissions from engines over the next 10 years, complementing other efforts to reduce CO2 emissions.

CSSC Chengxi Shipyard Co Ltd, a subsidiary of China State Shipbuilding Corporation, and CSSC Power (Group) Co., Ltd. on Sunday (4 February) signed an agreement for a methanol dual-fuel marine engine for an 85,000DWT bulk carrier in Shanghai.

According to the contract, CSSC Power Group will provide the methanol engine to CSSC Chengxi Shipyard. Both parties agreed they will carry out a close collaboration on the engine design of low-carbon and zero-carbon green ships.

CSSC Power Group will be actively involved in CSSC Chengxi’s ship development and design optimisation, while providing system solutions, to enhance the competitiveness of ship types.

Both parties agreed to cooperate and further contribute to the strategic goal of China State Shipbuilding Corporation to become a world-class shipping group.

NYK breaks ground to start construction of bio bunker fuel testing facility

Japanese shipping firm NYK on Tuesday (30 January) held a ceremony on January 29 to break ground at a site in Chiba Prefecture where the company will install a test engine facility to evaluate the safety of biofuels and accelerate their practical application as bunker fuels. 

NYK will complete the installation of the test engine in June and analyse the biofuel in combustion tests over the next three years. 

“The test engine will be a reused generator from the tugboat Sakigake, which is currently being converted to an ammonia-fuelled tug,” it said in a statement.

NYK Group companies Boltech Co., Ltd. and Nippon Yuka Kogyo Co., Ltd. will also participate in this project by utilising their engine-operation and fuel-oil-analysis technologies to verify the potential of various biofuels.

Biofuels are produced from various raw materials, including grains and waste cooking oil, but only a few are currently being commercialised. More types of biofuels are expected to be commercialised in the future as demand for biofuels increases. 

However, about a year of testing and analysis at an external engine facility, followed by 12 to 18 months of onboard trials, is needed before continuous shipboard use of new bunker fuels. 

“NYK expects to shorten the test period and the time until the new fuel can be used on board by owning and operating the test engine,” it added.

Manifold Times previously reported it will be conducting full-scale trials of long-term use of biofuel bunkers starting in fiscal 2024.

NYK at the time said it will use biofuel continuously for three months on multiple vessel types through the trial. After that, NYK will gradually extend biofuel use for a longer period for further validation.

ABC Engines to supply methanol marine engines for Jan De Nul cable-laying vessel

Jan De Nul Group and ABC Engines on Friday (26 January) announced their partnership for hybrid marine medium-speed engines that can run on biodiesel, HVO and methanol bunker fuels.

ABC will supply four 7,200 kW engines and one 1,800 kW engine for Jan De Nul Group's newest cable-laying vessel, Fleeming Jenkin

By switching to sustainable fuels in combination with the unique ULEv technology, this new cable-laying vessel will bring about a significant reduction of harmful emissions such as CO2, SOx, HC, particulate matter and NOx. By doing so, it meets the strictest standards in terms of NOx emissions onshore (Euro 6) and in terms of particulate matter emissions offshore (Stage V).

These innovative engines will ensure propulsion of the newest Jan De Nul Group's cable-laying vessel, Fleeming Jenkin. Using green methanol, the engines are also climate neutral and due to the unique combination with the ULEv technology they also meet the strict Stage V standard for particulate matter and Euro 6 standard for nitrogen.

Jan De Nul Group and ABC Engines are accelerating towards a more sustainable shipping industry with the development of these engines. Both companies take on a pioneering role to significantly reduce harmful emissions in the shipping industry and to contribute to a substantial positive impact on the climate and the health of man, fauna and flora.

An important step Jan De Nul Group is taking in making its fleet more sustainable, is switching to renewable fuels, such as methanol. Notwithstanding significantly reduced emissions of harmful greenhouse gasses, methanol also offers the advantage of being already available in more than one hundred ports around the world. In order to further shape the internal sustainability strategy and to fully align with the renewable world economy, Jan De Nul Group enters into this partnership with ABC Engines, which leads the way in the field of marine engines running on alternative fuels, such as the promising methanol.

Jan Van de Velde, Director Newbuilding at Jan De Nul Group, said: “The choice for ABC is based on a positive collaboration and shared vision of a sustainable future. Our cooperation results in high-quality engines that run on renewable fuel and are adapted to our vessels and needs of our customers. We prepare our fleet for the future, achieve a milestone within our sustainability goals and above all offer a positive contribution to the climate and health of man and animal."

Tim Berckmoes, CEO at ABC Engines, said: “Jan De Nul and ABC are two family-owned companies that always focus on the long term and use innovative technologies to realise the energy transition both locally and internationally. Thanks to the long-standing trust of our customers, we can continue to innovate, produce and invest in Flanders. This enables us to expand our export activities and further develop our manufacturing industry."
