The International Bunker Industry Association (IBIA) on Friday (22 September) published an article elaborating on guidelines for the safe design and operation of ships using alternative bunker fuels that were considered further by IMO’s CCC Sub-Committee (CCC 9) held from 20 to 29 September 2023:

A suite of guidelines for the safe design and operation of ships using alternative fuels (ammonia, hydrogen, LPG and other low flashpoint fuels) were considered further by IMO’s CCC Sub-Committee (CCC 9) held from 20 to 29 September 2023. Whilst progress was made on some aspects, and the draft LPG Guidelines finalised with a view to adoption at MSC 108 in May 2024, the draft guidelines for other alternative fuels require further work intersessionally for consideration and finalization at CCC 10 in September 2024 with a view to adoption at MSC 109 in December 2024.

Specific provisions associated with the bunkering of the alternative fuels, in respect of mitigation of the risks to the ship associated with the fuels, were considered in detail for ammonia and hydrogen. From the discussions it is clear that both present unique risks that require detailed consideration and provisions to mitigate those risks.

For ammonia it is not just the risks associated with toxicity, for example, to the extent that it may prevent the concept of safe-haven/refuge on board being applicable for certain ship types, that requires mitigation but also the corrosivity of the product and its effect on materials and so design of equipment. 

For storage, among the three different storage options for ammonia, i.e. refrigerated ammonia, semi-refrigerated ammonia and pressurized ammonia, only the former two should be considered for the purpose of the interim guidelines as a first stage, and that the use of pressurized ammonia systems would be possible through the alternative design process; portable tank provisions for ammonia should not be specifically developed.

For hydrogen the difficulty of containing leaks presents safety challenges and it was agreed that during bunkering operations leaks of hydrogen should be able to freely escape without accumulating to mitigate risk of fire or explosion. In this regard, as small leakages may form hydrogen pockets and coupled with hydrogen’s lower explosion limit and that it is impossible to de-energise electrical equipment in time, Emergency Shut-Down (ESD) principles have been removed from the current draft Guidelines.

Concerns were also expressed that ships using fuels such as LNG and methanol were being built with inadequate arrangements to debunker fuels (e.g. for pre dry dock preparations and emergencies (grounding, collisions)), due to a lack of related provisions in the IGF Code or Guidelines. It was decided not to include any such provisions at this time, but may be included when developing the draft interim guidelines for other alternate fuels such as hydrogen and ammonia.

A summary of progress is provided below.

Interim guidelines for the safety of ships using hydrogen as fuel

These draft guidelines have been developed further. They are goal-based and provide provisions for the arrangement, installation, control and monitoring of machinery, equipment and systems using hydrogen as fuel to minimise the risk to the ship, its crew and the environment. Additional intersessional work will be carried out with the aim to present the progress to CCC 10 (September 2024) with a view to finalization and adoption at MSC 109 in December 2024.

Interim guidelines for the safety of ships using ammonia as fuel

These draft guidelines have been developed further and provide an international standard for ships using ammonia as fuel. They are goal-based and will provide provisions for the arrangement, installation, control and monitoring of machinery, equipment and systems using ammonia as fuel to minimise the risk to the ship, its crew and the environment. Additional intersessional work will be carried out with the aim to present the progress to CCC 10 (September 2024) with a view to finalization and adoption at MSC 109 in December 2024.

Interim Guidelines for Use of LPG Cargo as Fuel

Due to the urgent industry need, CCC 9 developed these draft guidelines to provide unified specific guidance for ships using liquefied petroleum gas (LPG) cargo as fuel. Written in a goal-based manner they are expected to be agreed at MSC 108 in May 2024

Interim guidelines for the safety of ships using low flashpoint oil fuels

These guidelines are expected to provide an international standard for ships using oil-based fossil fuels, synthetic fuels and biofuels with a flashpoint between 52°C and 60°C. A Correspondence Group will continue to consider them and submit a report to CCC 10 (September 2024).

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.”
