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.

Chimbusco completes bunkering of China’s first 16,000K TEU methanol DF boxship

China Marine Bunker (PetroChina) Co Ltd (Chimbusco) completed a bunkering operation of the first domestically manufactured methanol dual-fuel container ship in Shanghai on 11 May, according to COSCO Shipping on Thursday (15 May). 

COSCO SHIPPING YANGPU was supplied approximately 900 metric tonnes (mt) of methanol marine fuel by Chimbusco at Pier 1 of COSCO Shipping Heavy Industry. 

The operation started on 7 May but was postponed due to unfavourable weather from the Jianghuai Cyclone.

COSCO Shipping said the operation marked an important achievement in green and low-carbon transformation in shipping, from ship construction and ecological layout of the entire green fuel industry chain of the company. 

Manifold Times previously reported the naming ceremony of China’s first 16,000 TEU methanol dual-fuel container ship, COSCO SHIPPING YANGPU in Yangzhou.

The methanol dual-fuel container ship named was the first in a series of vessels from COSCO Shipping Holdings, constructed by COSCO Shipping Heavy Industry Yangzhou.

Shell wraps up its first LNG bunkering operation for TUI Cruises in Barcelona

Energy giant Shell recently conducted its first LNG bunkering operation for TUI Cruises in Barcelona, according to Dexter Belmar, General Manager and Head of Global Downstream LNG on Thursday (22 May).

He said the milestone was achieved by Shell’s LNG bunker barge Haugesund Knutsen supplying the Mein Schiff Relax cruise ship.

“Barcelona, one of Europe and the Mediterranean’s leading cruise ports, is also a key LNG bunkering location for Shell as we help more cruise ships transition to lower-emission fuels,” he said in a social media post. 

“A huge thank you to Royal Caribbean Group for their trust, and to Knutsen and Port of Barcelona for their collaboration in making this bunkering safe and efficient.”

Belmar said LNG is leading the way as the preferred alternative bunker fuel in the cruise industry. 

“At Shell, we’re proud to support LNG fuelling needs at 26 locations worldwide, including major cruise ports like Bahamas, Barcelona, Canaveral, Everglades, Jamaica, Miami, Singapore, Southampton, and Tenerife,” he added.

IGU report: Global LNG bunkering fleet grows to 56 operational vessels by 2024

LNG bunkering fleet is concentrated in Europe with the highest capacity of operational bunkering vessels, followed by Asia/Asia Pacific and North America, according to 2025 World LNG report by IGU.

IGU report: Global LNG bunkering fleet grows to 56 operational vessels by 2024

The global operational LNG bunkering and bunkering-capable small-scale vessel fleet reached 56 units at the end of December 2024 with further support from expanding infrastructure and regulatory drivers such as the IMO’s ban of heavy fuel oil in Arctic shipping and the EU’s FuelEU Maritime regulation.

This was nine more vessels than in 2023, with a total added capacity of 82,900 cubic metres (m3). 

This was one of the major highlights in the 2025 World LNG report by the International Gas Union (ICU), which was launched at the 29th World Gas Conference (WGC2025) in Beijing on Thursday (22 May). 

IGU report: Global LNG bunkering fleet grows to 56 operational vessels by 2024

The LNG bunkering fleet is concentrated in Europe with the highest capacity of operational bunkering vessels. This is followed by Asia/Asia Pacific and then North America, both of which have seen rapid expansions in the past five years. 

As of the end of 2024, Europe has the highest bunkering capacity, with a total of 190,757 cm across 25 vessels currently in operation within the region. 

Asia/Asia Pacific has the second-highest bunkering capacity, with a total of 179,700 m3 across 17 vessels in operation. From that, China currently has five operational LNG bunkering vessels while South Korea currently provides STS bunkering services with four bunkering vessels. Singapore currently has three bunkering vessels in operation. 

North America continued its progress toward becoming a significant region in the LNG bunkering market in 2024, reaching a total capacity of 86,400 m3 across 10 operational vessels by year-end.

The report noted: “2024 was a significant year for LNG bunkering. Bunker users were quick to capture the reductions in both fuel costs and carbon emissions from using LNG, taking advantage of lower LNG prices relative to other marine fuels in 2024. Lower prices and an emerging LNG-fuelled fleet were catalysts in the large uptake in LNG bunker volumes.”

The Port of Singapore, which is the largest bunkering port in the world, recorded 463,900 tonnes of LNG bunkered in 2024, almost four times the 110,900 tonnes in 2023. The Port of Rotterdam, the second-largest bunkering port in the world, also recorded a 52% increase in bunkered LNG, from 620,000 cm in 2023 to 941,366 cm in 2024.”

IGU also said the newcomer in STS LNG bunkering is the Middle East with the LNG bunkering vessel Green Zeebrugge.

“The ship moved at the end of 2024 to Dubai and has performed the first ever LNG bunkering in the Middle East. This area is identified as a potential new LNG bunkering hub with Oman, the UAE, and Qatar as the main bunkering locations.”
