The Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (26 January) said it is pleased to award its ammonia bunkering safety study to a DNV-led consortium.

DNV, a globally established class society, is partnering with Surbana Jurong and the Singapore Maritime Academy (SMA). Surbana Jurong’s understanding of the local landscape will be critical to site identification for ammonia bunkering. SMA, part of Singapore Polytechnic, will co-develop workforce curriculum and provide manpower development in handling ammonia as a bunker fuel.

GCMD announced its first Invitation for Proposals “Defining the safety and operational envelopes to enable ammonia bunkering pilot and demonstration” on 8 October 2021 to a short list of classification societies and engineering consultants, and received a strong response upon its close.

Evaluation of the proposals was carried out by a team comprising industry experts with extensive experience and knowledge in this area, and the GCMD projects team.

A precursor to the demonstration of ammonia bunkering in Singapore, the intent of this study is to define a robust set of safety guidelines and operational envelopes that will establish the basis of a regulatory sandbox for trials at two local bunkering sites.

Handling ammonia as a bunker fuel will require more stringent safety and operational guidelines compared to transporting ammonia as a commodity given the substantively higher transfer frequency and the need for more flexible transfer configurations.

This study will build on guidelines that have been developed for safe handling of ammonia as a commodity by defining and then integrating or overlaying the guidelines required for safe handling ammonia as a bunker fuel.

While conducted in Singapore, this study can be calibrated to site-specific operational conditions to help advance the deployment of green ammonia as a bunker fuel elsewhere.

Professor Lynn Loo, the CEO of GCMD, said: “As with any new bunker fuel, there are safety and operational challenges associated with their use. GCMD has chosen to look at ammonia bunkering as its first project because ammonia is among the most energy-efficient green fuel to be produced.”

“This study to define the safety and operations envelopes for ammonia bunkering is critical to its eventual adoption anywhere. We have chosen to commission this study in Singapore; with Singapore being a population dense island nation and a major bunkering hub, the stringent guidelines developed in this study will likely be extensible to ports elsewhere.”

On news of the award, Knut Ørbeck-Nilssen, CEO of DNV Maritime, added: “Our research shows that a number of safety gaps hold the potential to disrupt the speed and success of shipping’s energy transition. The safe handling of ammonia – among the most promising future fuels – is one such gap which urgently needs to be closed, given the threat it poses to seafarers and ships unless properly managed.”

“We are therefore thrilled to partner with Surbana Jurong and Singapore Maritime Academy on this pioneering initiative, which we hope will lay the foundations for robust ammonia bunkering safety guidelines with industry wide applicability.”

Ahead of the award of this study, GCMD signed letters of collaboration with 21 industry partners who have agreed to share confidential technical information with the consortium so a robust set of recommendations can be made to regulators. (Annex A)

In addition, more than 30 organisations across the supply chain have registered to be part of the Industry Consultation and Alignment Panel (iCAP), set up by the centre to solicit input on the study recommendations. Interested companies may continue to register their interest to be part of the iCAP at this link: iCAP registration form.

The Maritime and Port Authority of Singapore (MPA), a founding partner of the Centre, will take the findings from the GCMD study into consideration to facilitate the development of a regulatory sandbox for future trials.

In parallel, GCMD has initiated discussions with the Singapore Maritime Institute (SMI) and the Centre for Excellence for Maritime Safety (CEMS) at the Singapore Polytechnic to operationalise the manpower development framework for training operators for the ammonia bunkering pilot.

“In any sustainable transition, a robust management of change process must always be in place where safety is mandatory to protect lives, the environment and investments,” said Dr Sanjay C Kuttan, GCMD Chief Technology Officer.

“The overwhelming support from both industry partners and iCAP members is testament to the importance of this study, and GCMD is committed to co-creating a positive impact with our partners as we navigate the challenges of maritime decarbonisation.”

The study will commence in February 2022 and is expected to take between 10 to 12 months to complete.

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.”
