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.

BHP and GCMD trial multi-feedstock B100 bio bunker fuel on bulk carrier

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.

The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).

The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).

Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.

The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.

At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.

Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.

The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.

Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.

The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.

This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier

Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier. 

In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.

In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.

The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions. 

Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.

NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.

“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.

VO Chidambaranar (VOC) Port Authority on Friday (29 May) said it has signed a Memorandum of Understanding (MoU) with India’s ammonia producer AM Green Ammonia to collaborate in the development of a green ammonia production plant.

The plant will have a capacity of one million tonnes per annum (MTPA) at Tuticorin.

The initiative also includes development of green ammonia handling, storage and bunkering infrastructure, pilot bunkering operations, safety procedures and training programmes. 

The project is expected to support the development of green fuel corridors connecting VOC Port with major ports in Europe and Asia, thereby strengthening India’s position in the global green fuels value chain.

VOC Port also signed a Memorandum of Understanding (MoU) with Bureau Veritas (India) Pvt. Ltd., to collaborate on Green Port certification, emissions accounting, ESG reporting, safety validation, development of green bunkering practices, and establishment of a Centre of Excellence for green fuels and sustainability.

The port also plans for an upcoming 750 m³ green methanol bunkering facility.
