The Global Centre for Maritime Decarbonisation (GCMD) on Tuesday (21 February) said it has successfully completed trialling two supply chains of biofuel blends sourced from different origins. 

The supply chain trials encompassed tracing biofuels from their production sites outside Singapore, to Singapore where the fuels were blended and bunkered. Lab testing of the fuels continued until they were consumed onboard. These trials took place from 31 October 2022–15 February 2023 and involved five vessels; approximately 4,700 MT of sustainable biofuel blends were bunkered, the last batch of which will be consumed by end of February.

Operationalising the trials together with our project partners

Two sustainable biofuel blends were used in our trials. One is Used Cooking Oil Methyl Ester (UCOME), a type of Fatty Acid Methyl Ester (FAME), blended with Very Low Sulphur Fuel Oil (VLSFO); the other is UCOME blended with High Sulphur Fuel Oil (HSFO). The UCOME used in both biofuel blends is produced from residue or feedstocks labelled 100% waste and is ISCC certified.

In the first supply chain, Chevron provided B24 VLSFO (24% biofuel blend) to CMA CGM Maupassant and MOL Endowment, the latter a vessel operated by ONE. Additionally, Chevron bunkered B20 HSFO (20% biofuel blend) in its own Singapore Voyager and in Elizabeth I.A. that is owned by Angelicoussis Group and managed by its oil tanker shipping unit, Maran Tankers Shipmanagement. In a separate supply chain, TotalEnergies Marine Fuels provided B24 VLSFO to Lycaste Peace that is owned by NYK and chartered to Astomos Energy Corporation.

GCMD as a neutral convenor

The supply chain trials were undertaken under business-as-usual conditions in which individual fuel purchasers nominated their fuel suppliers of choice, and bunkering took place with vessels on commercial routes. GCMD brought together marine fuel purchasers and suppliers, and balanced the dynamic needs of the many diverse stakeholders, vessel schedules, equipment and asset availabilities, spanning geographies and factoring in contingencies to complete the two supply chain trials. Alongside, GCMD coordinated with the surveyors, tracer technology and laboratory test providers to enable end-to-end tracing of biofuels during these trials. Collaborating and sharing transparently with willing project partners enabled these trials to take place successfully despite the complexities of the marine fuel supply chain and uncertainties in bunkering operations.

First announced at the end of July 2022, the full pilot involves 19 industry partners, with 13 vessels spanning the container, tanker, and bulker segments bunkering in Singapore and Rotterdam. The completed trials represent two of the five supply chains in the full pilot, which aims to establish an assurance framework for the supply chain of sustainable biofuels. This framework, to be further developed by GCMD and its partners, will also provide emissions abatement assurance for future synthetic and bio-derived drop-in fuels.

Ensuring traceability of sustainable biofuels supply chains

To ensure transparency and integrity of the supply chains for biofuels and biofuel blends from end-to-end, GCMD deployed a range of tracing techniques, including dosing with physical tracers, fingerprinting, and deploying a lock-and-seal methodology, all of which were complemented with laboratory testing and analyses at numerous pre-determined points from fuel production to consumption. The strong collaboration GCMD fostered with the marine fuel suppliers and purchasers ensured that the physical tracers were added, and biofuels and their blends were sampled as planned. This important partnership also allowed collection of shipboard samples and data along voyages so GHG emissions can be appropriately quantified. In addition, VPS witnessed the biofuel bunkering operations at all stages from source to supply, and conducted extensive laboratory tests to assess the quality of the biofuel and their blends. 

On lessons learned with the completion of two supply chain trials, Dr. Prapisala Thepsithar, director of projects at GCMD and project lead on this drop-in fuel assurance pilot, said: “Through these trials, we have gained a better appreciation of the complexities of real-world operations. We have learned the hard lesson that not all tracing techniques are directly applicable for tracing sustainable biofuels as they stand, and we are currently undertaking efforts to refine their deployment. I am grateful for the support from and flexibility of our project partners in overcoming the roadblocks encountered during our trials. These learnings will inform our subsequent trials in the months ahead.”

Over the three months during which the trials took place, the quality of the biofuel blends remained stable. With the data collected from the completed trials and additional data to be collected from the three other supply chains, GCMD is working with Boston Consulting Group (BCG), one of its Impact Partners, to develop a robust framework for GHG accounting and conduct cost-benefit analysis of deploying biofuels.

On GCMD completing its trials for two supply chains of sustainable biofuels, Dr. Sanjay Kuttan, CTO of the Global Centre for Maritime Decarbonisation, said: “The lack of assurance on the quality, quantity and emissions abatement of biofuels is a painpoint we identified from interviewing more than 100 industry stakeholders. These trials were curated to address this gap. In developing a framework to provide transparency and bolster the integrity of the biofuels supply chain, we hope to increase user confidence and decrease the barrier for wider adoption.”

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
