Maritime Blockchain Labs (MBL), a partnership set up between Lloyd’s Register Foundation and BLOC, on Tuesday said its bunker fuel assurance demonstrator system is set to enter a phase of further development as a key step towards commercialisation.

The next phase will involve the further development and scaling of the solution, capturing marine fuel deliveries and associated verified data into the system.

It is intended that this will be undertaken by a consortium formed of ship owners or operators, fuel suppliers, port authorities and a fuel testing body and MBL is inviting interest from stakeholders within these groups to join and co-sponsor this next phase of work. It is expected to begin January 2019.

The prototype digital system, providing fuel assurance for ship owners and suppliers, was developed earlier this year together with a consortium including the International Bunker Industry Association (IBIA), LR’s FOBAS team, Bostomar, Heidmar, BIMCO, Goodfuels and Precious Shipping. The demonstrator phase of the project was funded by Lloyd’s Register Foundation.

The successful development of a marine fuels quality tracing and compliance prototype involved testing in a simulated environment with the consortium in September this year.

The demonstrator closed with the prototype being used for the manual capture of the world’s first end to end fuel transaction on a blockchain in the Port of Rotterdam. The solution also won the team the prestigious MIT SOLVE competition, in the category of coastal communities.

“The recently concluded MEPC73 showed us that there are still burning questions about the availability of compliant fuels post-2020 – and the current epidemic of bad bunker, as it’s been called by Intertanko and others, shows that building traceability and trust in the marine fuels supply chain is one of the most vital issues facing shipping right now,” said Deanna MacDonald, CEO of BLOC.

“Our demonstrator phase has shown us that dealing with marine fuels’ quality and quantity assurance is an industry wide issue, and that the industry is looking to work together to solve this issue.

“We’ve built something that for the first time, will allow stakeholders across the global shipping industry to verify and validate transactions across the fuels supply chain.”

MBL’s bunker fuel assurance system uses Hyperledger Fabric blockchain technology. This technology creates an immutable chain of custody of quality analysis documentation and specification of fuels from the various actors transacting and transferring the fuels throughout the supply chain. The analysis results of the fuel supply are then associated or linked to the specific transaction offering this fuel.

Kongsberg Maritime to buy Finnish marine propulsion designer Steerprop

Kongsberg Maritime has agreed to acquire Finnish marine propulsion systems designer and manufacturer Steerprop, the latter said on Monday (7 September).

Steerprop has built a strong position as a specialised propulsion supplier, providing propulsion systems for icebreakers, polar research vessels, offshore support vessels and other demanding applications.

 The company has an installed base of more than 400 vessels globally and a significant order backlog, with the majority linked to Arctic and ice-class projects.

Steerprop CEO Riku-Pekka Hägg, said: “From day one, our mission has been to help customers solve complex challenges through innovative technology. Steerprop is growing heavily and have become the market leader in the Arctic propulsion segment, and as we considered the next stage of our journey, we carefully evaluated the strategic options for accelerating our growth. 

“It became clear that Kongsberg Maritime was the ideal partner, with a strong strategic fit, shared heritage, and local presence. Becoming part of Kongsberg Maritime secures the continuation of our legacy, preserves our expertise and know-how, and strengthens our position as the leading provider of azimuth propulsion solutions. Together, we’ll have the scale, resources, and expertise to innovate faster, serve our customers even better, and pursue our mission with even greater ambition.”

Ville Rimpilä, Senior Vice President – Thruster Systems, Kongsberg Maritime, said: “Steerprop has developed strong technology, valuable customer relationships and a leading position in Arctic propulsion. By combining their expertise with Kongsberg Maritime’s global reach and integrated solutions portfolio, we believe we can create additional value for customers while strengthening our position in a strategically important market.”

Both companies will continue to operate independently until the transaction has been completed. Existing projects, deliveries and contractual commitments remain unchanged, and ensuring continuity for customers will be the highest priority throughout the process.

Following completion of the transaction, the intention is to fully integrate Steerprop into Kongsberg Maritime in a phased and structured manner. 

The integration will focus on safeguarding customer relationships, maintaining delivery performance and retaining critical competence while gradually adopting common systems, processes and operating models.

Auramarine: Marine fuel flexibility will be key to shipping’s energy transition

Operators who adapt best will be the ones who built in the flexibility to their marine fuel strategy to respond as conditions change, says CEO John Bergman.

Finland-based fuel supply systems provider Auramarine on Wednesday (2 September) said it believes shipping’s energy transition is entering a phase where flexibility, not fuel choice, will determine which operators adapt successfully. 

With fuel price volatility, inconsistent alternative availability and tightening environmental regulation at different speeds across regions, Auramarine argued that the right approach to fuel supply infrastructure is now as strategically important as the fuel itself.

“The industry has spent years asking which fuel will win,” said John Bergman, CEO, Auramarine. 

“That may be the wrong question. No operator today can predict with confidence what will be available, compliant or commercially viable in five years. The operators who adapt best will be the ones who built in the flexibility to their fuel strategy to respond as conditions change.”

Auramarine’s own fuel split technology, first delivered in 2019 and now installed on around 20 vessels, reflects this thinking in practice. The retrofit system adds a fuel booster module onboard, allowing a ship to run different fuels through the same engine without the extended changeover procedures dual-fuel systems typically require.

This lets operators switch to MGO or biofuel, for example, to meet an ECA requirement, support maintenance schedules, or respond to fuel pricing shifts, without taking a vessel out of service. Delivered in sections through existing doors and hatches, it can be retrofitted to vessels already in operation.

Bergman sees this need for adaptability sharpening in sectors under the most operational and regulatory pressure. 

“Cruise and ferry operators feel this earliest and most acutely,” he said. 

“These vessels constantly move between regulatory zones and environmentally sensitive waters, so the ability to switch fuel supply without disrupting a schedule is an operational necessity. What’s notable is how many operators in this space still don’t know infrastructure like this exists, despite how directly it addresses what they’re already dealing with.”

Reliable flexibility requires a tailored approach, not just adding equipment. “The best results come from scoping flexibility to an owner’s actual fuel strategy, not adding complexity for its own sake,” Bergman added. 

Automated fuel changeover systems are designed to keep multi-fuel operations straightforward for crews, while a structured maintenance approach ensures inspection, testing and servicing can be carried out safely throughout the vessel’s lifecycle. This is where Auramarine’s lifecycle services play a central role, supporting operators well beyond initial installation with the ongoing servicing, spares and technical support needed to keep flexible fuel systems performing reliably for the long term, whatever the fuel landscape looks like in years to come.

“Over the next few years, operators who succeed will be the ones who stopped waiting for certainty and started building optionality instead,” Bergman added

“In a transition this uncertain, adaptability matters more than any single fuel bet. That’s the conversation we want the industry to have.”

TFG Marine advances global MFM rollout with two US Gulf bunker barges

Global marine fuel supply and procurement firm TFG Marine on Wednesday (2 September) said it continued to expand mass flow meter (MFM) technology across its US Gulf Coast bunker fleet.

The company said two more vessels, Buffalo B414 and Buffalo B304, were recently fitted with the equipment.

“Both supply barges received ISO 22192 certification for their newly installed MFMs last month, giving customers greater confidence in bunker quantity measurement while supporting a more accurate, transparent and efficient delivery process,” TFG Marine said in a social media post. 

“This marks the latest step in TFG Marine’s ongoing investment in technology and best practice across its global bunkering operations, and forms part of a broader push by our North America team to help drive progress across the region’s bunkering industry.”

Last year, TFG Marine announced it reached a key milestone in its global digitalisation programme with the installation of an ISO 22192-compliant MFM on the Buffalo 404, a barge on time charter from American bunker barge company Buffalo Marine Service Inc.

This was the first ISO-certified MFM-equipped bunkering barge operating in the US Gulf.

The installation was part of TFG Marine’s wider strategy to equip close to 90% of its global bunkering fleet with MFMs by 2026 as a commitment towards improving data integrity, streamlining operations and strengthening trust in marine fuel transactions.
