Finnish marine technology supplier Wärtsilä and Swedish shipping company Furetank are co-developing and testing two technologies showing the potential to halve the methane slip, according to the latter on Wednesday (20 August). 

Furetank said running vessels on LNG/LBG brings many benefits compared to conventional fuel oil, reducing emissions of CO2, NOx, SOx and harmful particles.

“But a much debated downside is the methane slip: the release of unburned gas fuel, not fully combusted in the engines,” it said in a statement. 

“Although the combustion rate is generally high and the methane slip accounts for a very small fraction of the fuel used, methane is a more potent greenhouse gas than CO2. Thus, this slip is the most critical technical challenge to overcome in gas-fueled vessels; a challenge which Wärtsilä and Furetank are now countering.”

Two technical solutions have been tested in Furetank’s Vinga series tankers. One of them is a Greenhouse Gas (GHG) reduction package, developed by Wärtsilä for dual fuel engines. The GHG package actively controls the engine while working in demanding conditions like manoeuvring, harsh sea conditions or varying fuel quality. This way, combustion is optimised and unburned gas emissions minimised.

The other solution is the Low Load Optimization package, reducing the methane slip at low engine loads, for example during harbour operations like loading and unloading. This package actively balances the loading of each engine cylinder, optimising the overall total engine efficiency even at a low engine load.

The tests performed, both in the laboratory and at sea, show very promising results. The methane slip was reduced by 45 to 50%.

“These are great results, far exceeding what we had expected or technically believed. The tests show a significant impact in absolute terms. We believe many shipping companies will be interested in these solutions. And this is not the end of the road, there is more to be done,” Göran Österdahl, sales director of marine power at Wärtsilä, said. 

“This is a very successful collaboration, as Furetank has asked us for solutions and offered to perform tests in real-life conditions. We are in a phase of intense research and development on future fuels, making it invaluable for us to find test-willing partners. Our entire industry will need to establish many operator/product developer collaborations. Otherwise progress will be too slow.”

For Furetank, this is yet another step in progressing the emission-reducing technology in the Vinga vessel series, designed by Furetank with partners and the globally most energy efficient ships in their segment according to the IMO EEDI index.

“We had many discussions with Wärtsilä during the past years on how to counter the methane slip. It is a tough nut to crack and the most important technical issue for us to solve. There is an ongoing chase for new engine solutions which will only intensify with the EU ETS system and stricter IMO regulations. We are happy to have this fast track to developers and manufacturers of advanced engine technology,” Clas Gustafsson, Technical Manager at Furetank, said. 

The functionality will be implemented in the Vinga sister vessels currently being built at the China Merchants Jinling Shipyard in Yangzhou, and retrofitted into all earlier ships in the series.

CMA CGM takes delivery of fourth LNG-fuelled containership

French shipping giant on Wednesday (19 June) said it celebrated the naming ceremony and delivery of its fourth LNG-fuelled container ship, CMA CGM Tivoli.

Organised at HD Hyundai Mipo in Ulsan, South Korea, on 16 June, the event marked the official entry of the fourth vessel in a series of ten specially designed for Northern Europe feeder services.

“Featuring optimised features for 45-foot containers, increased capacity for refrigerated containers, and innovative forward accommodation to enhance cargo loading and aerodynamics, CMA CGM Tivoli distinguishes itself with a high ‘length to beam" ratio to maximise hydrodynamic efficiency,” the firm said in a social media post. 

“She departed the shipyard on June 15th, 2024, bound for Busan. We wish fair winds and smooth seas to Captain Artur Dumbrov and his crew.”

Mitsubishi Shipbuilding receives orders for Japan’s first methanol-fuelled RoRo cargo ship duo

Two ships will be built at the Enoura Plant of MHI’s Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture, with scheduled completion and delivery by the end of fiscal 2027.

Mitsubishi Shipbuilding receives orders for Japan's first methanol-fuelled RoRo cargo ship duo

Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, on Wednesday (19 June) said it has received orders from Toyofuji Shipping and Fukuju Shipping for Japan's first methanol-fueled roll-on/roll-off (RORO) cargo ships. 

The two ships will be built at the Enoura Plant of MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture, with scheduled completion and delivery by the end of fiscal 2027.

The ships will be approximately 169.9 meters in overall length and 30.2 meters in breadth, with 15,750 gross tonnage, and loading capacity for around 2,300 passenger vehicles.

A windscreen at the bow and a vertical stem are used to reduce propulsion resistance, while fuel efficiency is improved by employing MHI's proprietary energy-saving system technology combing high-efficiency propellers and high-performance rudders with reduced resistance. 

The main engine is a high-performance dual-fuel engine that can use both methanol and A heavy fuel oil, reducing CO2 emissions by more than 10% compared to ships with the same hull and powered by fuel oil, contributing to a reduced environmental impact. 

In the future, the use of green methanol(2) may lead to further reduction in CO2 emissions, including throughout the lifecycle of the fuel. Methanol-fueled RORO ships have already entered into service as ocean-going vessels around the world, but this is the first construction of coastal vessels for service in Japan.

In addition, the significant increase in vehicle loading capacity and transport capacity per voyage compared to conventional vessels will provide greater leeway in the ship allocation schedule, securing more holiday and rest time for the crew, thereby contributing to working style reforms.

Mitsubishi Shipbuilding, to address the growing needs from the modal shift in marine transport against the backdrop of CO2 reductions in land transportation, labor shortages, and working style reforms, will continue to work with its business partners to provide solutions for a range of societal issues by building ferries and RORO vessels with excellent fuel efficiency and environmental performance that contribute to stable navigation for customers.

A.P. Moller – Maersk (Maersk) on Wednesday (19 June) said it will be christening one of the world’s first methanol-enabled vessels when it arrives in Los Angeles this August.

The firm invited the public to go aboard the container ship in Los Angeles.

Powered by methanol for its maiden voyage and capable of carrying more than 16,000 containers (TEU), the vessel will get its new name at a private ceremony at the Port of Los Angeles Outer Harbor on Tuesday, August 27. 

Maersk’s CEO Vincent Clerc will be on hand, alongside special guest speakers from Nike and leading state and local officials. Nike is a partner in the name-giving event.

“Nike is committed to protecting the future of sport and we leverage science-based targets to guide us through our Move to Zero journey,” said Venkatesh Alagirisamy, Nike Chief Supply Chain Officer.

“Operating one of the largest supply chains in the world, we have a responsibility to advance the innovation and use of more sustainable methods that get us closer to zero carbon and zero waste. By working with suppliers like Maersk, who share our commitment to sustainability, we are scaling our use of biofuels in ocean transportation, our main first-mile delivery channel.”

“This event is not only an opportunity to celebrate a remarkable engineering achievement, but the chance to highlight that we can navigate towards more sustainable supply chains if we work together,” said Charles van der Steene, Regional President for Maersk North America.

On Wednesday, August 28, Maersk invites the public to tour the 350-meter-long vessel, which will be sailing from Asia. Visitors will be able to see the Sailors’ living quarters and even stand on the bridge from where the captain controls the vessel. Public tours will require visitors register for a free ticket via an online registration site that will be activated and announced in August.

This is the fifth container vessel in Maersk’s fleet that can sail on green methanol bunker fuel.
