Gas supply chain risk management firm Bureau Veritas on Tuesday (21 April) said a group of leading companies in maritime transportation have taken up the challenge of investigating the realities of using ammonia (NH3) as a marine fuel, with specific focus on addressing technical and safety challenges.

Ammonia is one of a number of options to be a marine fuel of the future. One of the key elements in the group’s approach is to look at the broader spectrum of implications for many ship types and different operational requirements, including bunkering and port operations, it says. 

The company noted a first step was to hold a hazard identification workshop (HAZID) to understand the risks involved with using ammonia as a marine fuel. This was held in February 2020 at MAN Energy Solutions’s office in Copenhagen. 

“Ammonia is a carrier for hydrogen which can be generated from renewable energy and ammonia storage and transportation can, in principle, be managed with established technologies,” said Panos Koutsourakis, Global Technology Leader for Sustainable Shipping at Bureau Veritas.

“But ammonia is both toxic and corrosive. We need to understand, if and how, the associated risks can be managed to merit further practical and commercial development – especially confirming the potential for stable combustion and NOx emissions. 

“Furthermore, potential availability is not yet assured. Sufficient availability of ‘green’ ammonia would require the scalable development of ‘Power-to-X’ technologies to provide the volumes necessary for shipping.”

In comparison with conventional heavy fuel oils, ammonia is less energy dense, can be liquefied at -33°C, and stored at atmospheric pressure for use as a marine fuel, explains Bureau Veritas.

Currently, aspects of using ammonia are not explicitly covered by the existing regulatory framework – notably IMO’s International Code of Safety for Ship Using Gases or Other Low-flashpoint Fuels (the IGF Code), and require specific attention, notes the company.

The group will perform detailed risk studies to assess the technical feasibility and specific safety risks of ammonia fueled ships with a view to considering its potential as a safe fuel for the decarbonization of shipping, it adds. 

The company says the HAZID workshop held at MAN’s offices in Copenhagen was the first of these studies.

It noted that the workshop was carried out to identify the safety and operational hazards associated with the use of ammonia as fuel for propulsion on a VLCC. 

The study led to the identification of practical safeguards and recommendations which should be considered in order to lower the risks to As Low as Reasonably Practicable (ALARP), said Bureau Veritas. 

It added that the study also covered: NH3 storage space and bunker stations, NH3 Fuel Treatment Room and HP Fuel Pump Room (combined), Engine Room (Gas-safe), Vent/Safety system lines and Vent Mast and ship’s operations.

Further studies planned by the group will include addressing operational hazards and looking more in-depth at conceptual designs based on different vessel types, it concludes. 

The companies participating in the group include:

Alfa Laval, Bureau Veritas Marine & Offshore, Capital Ship Management Corp, C-Job Naval Architects, CMB, DFDS, ENGIE, Exmar, Gaslog LNG Services Ltd, Gaztransport & Technigaz (GTT), MAN Energy Solutions, MOL, NYK, Samsung Heavy Industries, Shell International Trading and Shipping Company, Society for Gas as a Marine Fuel (SGMF), Star Bulk, Stena Teknik and Stolt Tankers.

MPA and MSC ink MoU to support adoption of alternative bunker fuels

The Maritime and Port Authority of Singapore (MPA) on Wednesday (3 June) said it signed a Memorandum of Understanding (MoU) with MSC Mediterranean Shipping Company to strengthen collaboration in maritime decarbonisation, digitalisation, innovation, and manpower development. 

The MoU was signed on 25 May 2026 by Mr Ang Wee Keong, Chief Executive of MPA, and Mr Soren Toft, Chief Executive Officer of MSC.

The MoU underscores the shared commitment of MPA and MSC to foster a sustainable, digital, and future-ready maritime sector, while enhancing MSC’s operational and business activities in Singapore. This year also marks the 30th anniversary of MSC establishing its Asia Regional Office and local office in Singapore.

Under the MoU, MPA and MSC will explore new routes and services to strengthen connectivity, support the adoption of alternative marine fuels such as bio-LNG, and advance technologies to improve vessel energy efficiency and operational performance.

MPA and MSC will also collaborate on maritime digitalisation initiatives to improve operational efficiency, including streamlining vessel arrivals and port operations. 

On manpower development, MSC will support internship and scholarship opportunities through Singapore Maritime Foundation’s Maritime Outreach Network (MaritimeONE) platform, an industry-led tripartite partnership comprising industry, government and institutes of higher learning that aims to raise awareness of the maritime industry and attract quality talent into the maritime sector.

Mr Ang Wee Keong, Chief Executive of MPA, said: “This partnership reflects the strong collaboration between MPA and MSC in driving sustainability and digitalisation in the maritime sector. By working together on decarbonisation, operational efficiency and talent development, we aim to strengthen Maritime Singapore’s position as a trusted and future-ready global maritime hub.”

Mr Soren Toft, Chief Executive Officer of MSC, said: “Singapore is a strategically important hub for MSC and a key gateway to the broader Asia region. As we mark 30 years in Singapore, this MOU reinforces our long-term commitment to strengthening our presence here. MSC and Singapore are closely aligned on the priorities shaping the future of global shipping, and we look forward to deepening this partnership to drive the continued growth and resilience of the maritime industry.”

Seaspan and Hapag-Lloyd complete first of five methanol vessel retrofit

Seaspan Corporation (Seaspan) and Hapag-Lloyd on Wednesday (3 June) announced the successful completion of the first of the five vessel conversions under their methanol retrofit programme with the delivery of Seaspan Yangtze.

From the early SAVER (Seaspan Action for Vessel Energy Reduction) programme to today’s CleanBlue initiative, Seaspan has committed over USD 230 USD million across 86 vessels, executing more than 550 efficiency and retrofit projects.

Following Seaspan Yangtze, the remaining vessels planned for retrofit under the programme are Seaspan Amazon, Seaspan Ganges, Seaspan Thames, and Seaspan Zambezi. Each retrofit is expected to reduce well-to-wake CO₂e emissions by approximately 30,000 to 50,000 metric tonnes per vessel annually when operating on low-carbon methanol, while also extending vessel lifespan and enhancing fuel flexibility.

“Decarbonisation is not just about building the fleet of tomorrow, it is also about unlocking the full potential of the fleet we have today. Retrofitting and upgrades on existing fleets play a practical, immediate, and economical role in accelerating shipping’s decarbonization journey,” said Bing Chen, Chairman, President and CEO of Seaspan. 

“Project SAVER CleanBlue highlights Seaspan’s strong customer partnerships, deep technical expertise, and unique platform integrated with JV partners, such as WattSpan Maritime Technology, in executing complex and large-scale retrofit projects.”

“The successful conversion of the Seaspan Yangtze together with the planned retrofit of its four sister vessels is another important step on our ambitious path towards net-zero fleet operations by 2045,” said Silke Lehmköster, Managing Director, Fleet, Hapag-Lloyd. 

“Together with Seaspan, we are demonstrating that retrofitting existing vessels for low-carbon methanol can be a practical way to reduce emissions in shipping.”

South Korean-led nuclear car carrier design secures LR backing

Classification society Lloyd’s Register (LR) on Tuesday (2 June) said it has teamed up with South Korean shipbuilding, marine services and nuclear research organisations to advance the development of a nuclear‑assisted car carrier concept. 

LR is working with Hyundai Heavy Industries, Korea Shipbuilding & Offshore Engineering (KSOE), Hyundai Glovis, G- Marine Service and the Korea Atomic Energy Research Institute (KAERI) on a joint development project (JDP) exploring an advanced small modular reactor (SMR) installation on a pure car and truck carrier (PCTC). 

The study focused on how a Molten Salt Reactor (MSR) could be physically and operationally integrated into a large vehicle carrier. Work examined the internal arrangement and segregation of the reactor system, shielding requirements, and the impact on cargo deck layout and vehicle capacity, alongside stability and trim implications linked to the reactor’s weight and positioning. 

The partners also assessed propulsion system configuration and power delivery, as well as operational flexibility compared with conventionally fuelled PCTCs, where trade routes and port calls can be tightly constrained. 

A key focus of the project has been safety. LR led hazard identification (HAZID) and preliminary risk assessment work, focusing on containment, onboard safety systems and potential operability constraints tied to nuclear technology at sea. 

The partners will mark the project milestone with an Approval in Principle (AiP) granting ceremony on 2 June at the LR stand during Posidonia 2026. 

Sung-Gu Park, President – North East Asia, Lloyd’s Register, said: “While nuclear propulsion is still at an early stage of development, this project shows the importance of building technical understanding now to support future progress. 

“Establishing feasibility at concept stage is a valuable step forward, particularly in areas such as cargo optimisation, vessel stability and integrated safety design.” 

Hong-Ryeul Ryu, CTO and Senior Executive Vice President at HD HHI, said: “With global environmental regulations becoming increasingly stringent and no definitive net-zero fuel yet available, SMR-powered ships can serve as a highly effective alternative, representing a pioneering next-generation maritime technology capable of complying with GHG emission regulations while allowing lifetime operation without refuelling, and HD HHI will remain at the forefront of sustainable maritime technology development.”
