Furetank, Wärtsilä test solutions showing potenting in halving methane slip

Duo are testing GHG reduction package and Low Load Optimization package on Furetank’s Vinga series tankers; tests performed show methane slip was reduced by 45 to 50%.

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.

Singapore-based Eastern Pacific Shipping (EPS) on Wednesday (28 February) said it signed two new contract orders in a signing ceremony in Shanghai, one for a series of ammonia dual-fuel bulk carriers with CSSC Beihai Shipbuilding and another for a series of LNG dual-fuel oil tankers with CSSC Guangzhou Shipbuilding International. 

The contracts signed cover four 210,000 dwt ammonia dual-fuel bulk carriers and two 111,000 dwt LNG dual-fuel LR2 oil tankers, expanding our fleet of green vessels on water. 

“These are pivotal for EPS, testament to our continued commitment towards the decarbonisation of shipping,” EPS said in a social media post.

Manifold Times recently reported EPS signing a contract for its first ever wind-assisted propulsion system, partnering with bound4blue to install three 22-metre eSAILs® onboard the Pacific Sentinel

The turnkey ‘suction sail’ technology, which drags air across an aerodynamic surface to generate exceptional propulsive efficiency, will be fitted later this year, helping the 183-metre, 50,000 DWT oil and chemical tanker reduce overall energy consumption by approximately 10%, depending on vessel routing.

Port of Tanjung Pelepas Sdn Bhd (PTP), a joint venture between MMC Group and APM Terminals, on Wednesday (28 February) announced a significant milestone with the successful completion of its first Liquefied Natural Gas (LNG) bunkering operation. 

The landmark event involved the CMA CGM Monaco, a 14,024 TEUs (Twenty-foot Equivalent Units) capacity containership operated by French shipping giant, CMA CGM.

Tan Sri Che Khalib Mohamad Noh, Chairman of PTP in a statement remarked this latest milestone demonstrates PTP’s commitment to continuously enhance its competitive advantages in an increasingly competitive global market.

“The successful completion of our first LNG bunkering operation also underscores our unwavering commitment to sustainability and environmental leadership. We are proud to partner with Petronas Trading Corporation Sendirian Berhad (PETCO) and CMA CGM on this initiative and showcase PTP’s capabilities as a leading facilitator of clean and efficient maritime operations.”

“This milestone paves the way for further growth in LNG bunkering at PTP, contributing significantly to the decarbonisation of the maritime industry.”

Commenting on this achievement, Mark Hardiman, Chief Executive Officer of PTP stated this latest milestone further highlights PTP’s position as the largest transshipment hub terminal in Malaysia.

“In preparation for the LNG bunkering operation, PTP worked closely since March 2022 with PETCO and CMA CGM, as well as with various other related government agencies to organise table-top exercises (TTX) and workshops, before carrying out the deployment exercise.”

“The success of the bunkering operation is a result of the seamless collaboration and preparations involving rigorous safety procedures through in-depth operational and risk assessments, modelling, and validation. We thank PETCO, CMA CGM all other involved parties for their joint efforts in operationalising the bunkering capability and we welcome partners to work with us to accelerate maritime decarbonisation,” said Hardiman.

Port of Tanjung Pelepas (PTP) is Malaysia’s largest transshipment hub with the capacity to handle 13 million TEUs annually. The port delivers reliable, efficient, and advanced services to major shipping lines and box operators, providing shippers in Malaysia and abroad with extensive connectivity to the global market. PTP is currently ranked 15th among the world top container ports.

Wallenius Wilhelmsen PCTC order

Roll-on/roll-off (Ro-Ro) shipping company Wallenius Wilhelmsen on Tuesday (27 February) declared options to build four additional next-generation Shaper Class pure car and truck carrier (PCTC) vessels.

The 9,300 CEU methanol dual fuel vessels can utilise alternative fuel sources, such as methanol, upon delivery. They will also be ammonia-ready and able to be converted as soon as ammonia becomes available in a safe and secure way.

“Together with our customers we are committed to further shaping our industry and accelerating towards net zero. These new vessels are a vital part of that journey,” says Xavier Leroi, EVP & COO Shipping Services.

This latest commitment brings the total number of Shaper Class vessels currently on order with Jinling Shipyard (Jiangsu) to eight. Wallenius Wilhelmsen also retains further options.

The first of the Shaper Class vessels already ordered are expected to be delivered in the second half of 2026. The four additional vessels under the declared options will be delivered between May and November 2027.
