UK-based classification society Lloyd’s Register (LR) on Wednesday (24 February) said little more than a year after a Joint Development Project (JDP) to develop an ammonia-fuelled tanker design was launched by LR, MISC Berhad, MAN Energy Solutions (MAN) and Samsung Heavy Industries (SHI), the partners have received a welcome boost.

Yara International ASA, a giant Norwegian chemicals company and major ammonia producer, and the Maritime and Port Authority of Singapore (MPA) have signed up to join what has been named ‘The Castor Initiative’, taking the JDP partnership to six.

The naming of the project is significant, noted LR. Castor is the second-brightest star in the Gemini constellation, but actually consists of six stars which appear as one.

In a webinar yesterday hosted by Randall Krantz, a Senior Project Adviser at the Getting to Zero Coalition, the partners revealed that they are on track to design, build, and commission the world’s first ammonia-fuelled tanker by 2025.  

Since the project began in January 2020, LR has made significant progress in early safety appraisals and research into the development of suitable fuel storage and supply systems, and the necessary risk assessments that will be required. 

“Demonstrators like this are critical for 2050,” said LR’s Marine and Offshore Director, Mark Darley.

“Zero-carbon vessels are a reality and need to enter the fleet by 2030. They will be ready before the shoreside infrastructure. But we will all learn from this project, and others like it, which will help in future developments and save money in the longer term.”

Meanwhile, MAN has made considerable progress in identifying the engineering parameters that will need to be adapted to use ammonia as a fuel in an internal combustion engine.

Brian Østergaard Sørensen, a MAN Vice President and Head of Research & Development into two-stroke engines, confirmed that the technology is available and ammonia is an interesting fuel option. 

Conceding that there are certainly safety challenges relating to its use as a marine fuel, he said that the chemical is relatively easy to handle, already widely shipped by sea and well-known in the industry. 

SHI is already working on the design of a tanker and will build the vessel when the time comes. The shipbuilder’s Vice President of Shipbuilding & Drilling Sales Engineering, Haeki Jang, emphasised the importance of a first demonstrator vessel as a means of minimising uncertainty. The project, he said, was essential to identify challenges along the way. 

MISC will own and operate the tanker. The Group’s President and Chief Executive, Yee Yang Chien, highlighted the fact that the project involves different stakeholders with a common goal. The collaboration is encouraging, he said, because the industry needs “multiple parallel initiatives” like this.

The partners emphasised the importance of the new members. With Yara International, the six-party collaboration now includes one of the world’s largest ammonia producers and a pioneer in the development of green ammonia, which is produced without using any carbon-related energy. 

Rob Stevens, the company’s Vice President of Ammonia Energy and Shipping, joined the webinar after Yara’s involvement had been announced. “Ammonia can be an enabler in the energy transition and especially towards zero-emission shipping,” he declared. 

The company has been producing fertilisers using renewable energy for many decades, he revealed, and has successfully produced green ammonia in the past. The company plans to re-start green ammonia production, he said, and its experience in addressing the risk of emissions at its ammonia plants would contribute knowledge to the JDP.    

Meanwhile, Singapore’s MPA will add its expertise to safety regulations relating to ammonia infrastructure and bunkering operations.

LR notes the partners recognise that even more collaboration is needed to complete the chain, not only in this project, but in shipping’s decarbonisation process generally. MISC’s Yee Yang Chien welcomed the new participants but pointed out that shipping’s banks, financiers and customers also “need to join hands with us”.

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.”
