Classification society DNV on Friday (17 September) said it has awarded Navigator Gas an Approval in Principle (AiP) for a new ammonia fuelled gas carrier design.

An industry wide consortium, including MAN Energy solutions, Babcock International, and the Norwegian Maritime Authority (NMA), has collaborated with Navigator Gas to achieve the Approval in Principle (AiP) from DNV. 

The new gas carrier design has been awarded the AiP based on the special features notation (GF NH3) under DNV’s new rules for the use of ammonia as fuel in gas carriers. DNV, alongside the NMA, reviewed the design and relevant documentation and found no potential showstoppers to its realisation.

“Navigator Gas has been discussing Ammonia as a fuel with our consortium partners since 2018, when this topic was on the fringes of discussions surrounding decarbonisation and the use of alternative fuels,” says Paul Flaherty, Technical Advisor to Navigator Gas.

“Those early discussions on feasibility led to the completion of a comprehensive HAZID in early 2019, which remains as valid today as it was then. This has also been used as the base safety case during our AiP discussions with DNV. 

“Since our discussions began, we have witnessed an exponential increase in the number of projects around the globe looking at Hydrogen and Ammonia as carbon free source of energy. We have also been engaging with our customers and business partners to discuss their carbon free shipping requirements for transporting Blue/Green Ammonia to their customers.”

“Obtaining an AiP from DNV for an Ammonia fuelled vessels is the first step in preparing Navigator Gas to meet the future demands of our customers and to reduce our carbon footprint through lower greenhouse gas emissions.

“In the longer term, using Ammonia as fuel is one of Alternative Fuels options we are pursuing, along with CCS, Carbon Offsetting and improved Vessel Optimisation to reduce our carbon footprint and lower greenhouse gas emissions.

“I would like to thank DNV, MAN Energy Solutions, Babcock International and the Norwegian Maritime Authority, for their unwavering support and input during the AiP process,” he ends.

“We are very pleased to be working with Navigator Gas and so many leading companies on this AiP,” says Torgeir Sterri, Senior Vice President, Regional Manager West Europe, DNV Maritime. 

“If our industry is going to continue to play a central role in the global economy, we need to be exploring all options that can get us further towards decarbonisation.

“At the same time, we recognise that for our customers, how to tackle the decarbonisation challenge is going to be most challenging and significant decision they are likely to make this decade. This is why we have created class notations and guideline that give them the flexibility to find the path that fits their operations and business.”

Andrew Scott, Business Development Director, Babcock LGE comments:
“This ammonia as a fuel concept design is supported by Babcock LGE’s operational experience of delivering Liquefied Petroleum Gas (LPG) fuel supply systems and carrying ammonia as a cargo on gas carriers, meaning specific issues occurring when utilising ammonia as a fuel are well understood, resulting in an inherently safe design.”

“Babcock LGE is enabling the transition towards a cleaner, sustainable future through innovative technologies, and we are delighted to be working with our partners in this significant project.”

Thomas S. Hansen, Head of Promotion and Customer Support, MAN Energy Solutions explains:
“MAN Energy Solutions is happy to work with industry partners in decarbonising the maritime economy where, for us, the path starts with fuel decarbonisation. Here, several zero-carbon fuels offer significant potential, with ammonia of especial interest.”

“Since large quantities of ammonia are already transported around the world, it is a well-established commodity and using it to power ships would be a natural step.

“In this context, we have already announced that we expect to be make a dual-fuel, two-stroke ammonia engine commercially available for large-scale ocean-going ships by 2024, followed by a retrofit package to make existing maritime vessels capable of running on ammonia by 2025.”

Lars Alvestad, acting Director of Shipping and Navigation, Norwegian Maritime Authority notes:
“We are proud to be a part of this project and it has given us vital input on how to handle the safety concerns when using ammonia as fuel. Ammonia could play an important role in the decarbonisation of shipping and therefore the safety concerns have to be addressed.”

“This project shows that it’s possible to manage some of the challenges within decarbonisation through good cooperation.”

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.”
