Classification society American Bureau of Shipping (ABS) on Wednesday (21 April) published its latest support for the marine and offshore industry’s decarbonisation drive, that includes a detailed life-cycle, or value-chain, analysis of the greenhouse gas (GHG) footprint of the leading alternative marine fuels.

The first-of-its-kind analysis is the heart of the third edition of the ABS Low Carbon Shipping Outlook series, where ABS also updates on the marine sector’s progress on reducing emissions and showcases potential designs for future vessels, including their prospective technical and economic data.

ABS collaborated with Herbert Engineering to explore the feasibility of transitioning from three conventional vessel designs to low carbon variants. The research identified differing degrees of difficulty, depending on a range of factors including maturity of technology and required degree investment.

“Shipowners need to be conscious of using the lessons from the transition to decarbonization to build a cycle of continuous process improvement,” said  Christopher J. Wiernicki, ABS Chairman, President and Chief Executive Officer.

“They can do this by understanding the impact of decarbonization on all aspects of their business and using that information to power the cycle. This latest Outlook comprehensively underscores how ABS continues to lead the industry in this area.”

Setting the Course to Low Carbon Shipping – View of the Value Chain is the third in a series of outlook documents published by ABS to showcase the latest decarbonization research and thinking.

The first in the series, 2030 Outlook — 2050 Vision, examined the International Maritime Organization mandated emissions goals and the varying levels of carbon impact from available marine fuels and other energy sources as shipowners strive to meet those goals.

The second in the series, Pathways to Sustainable Shipping, examined the current energy-commodity and consumer trends, and how they could influence the size of the global fleet, its trading patterns and, therefore, its emissions output. 

“The third Sustainability Outlook from ABS conforms to the standards set by its two predecessors in being a well-researched and presented document. While no one has a crystal ball to predict the future, it is extremely useful to have this report which helps to summarize the current state of thinking and experience in the area of carbon emission reduction,” said Richard Gilmore, Executive Vice President, Maran Gas Maritime Inc.

“This topic will continue to be of pressing importance for all aspects of shipping for years to come and these reports help organize the growing body of information in this fast evolving field. It is a ‘must read’ for all shipping executives.”

“The ABS Outlook is a valuable contribution as it is now of essence to urgently concretise the future pathways, demonstrating what the future will look like and identifying risks and further development needs,” added Bo Cerup-Simonsen, CEO, Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping. 

“We look forward to further progressing the pathways and solutions through our partnership in the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping.”

While the industry focus has been on reducing shipping’s carbon footprint, pressure is growing for every link in maritime trade’s value chain to follow suit, including supporting land-side infrastructure. ABS worked with the Rocky Mountain Institute to ensure that View of the Value Chain looks at both. 

ABS and Herbert Engineering examined the potential technical requirements and operational trade-offs that may be necessary in future versions or conversions to low carbon operations of three existing ship types: a Chinamax Bulk Carrier, an Aframax Tanker and a Feeder Containership.

The report also explores the innovative carbon-reduction practices presently being deployed at ports and other land-side value chain elements as the sector transitions towards a more sustainable business model.

“View of the Value Chain is a response to how shipowners’ strategic industry partners are encouraging them to intensify their focus on the entire value chain, not just the combustion cycle, when deciding which measures to take to reduce their collective carbon footprint,” noted Georgios Plevrakis, ABS Director, Global Sustainability.

“Meanwhile financiers and charterers increasingly appear poised to set the requirements for the environmental performance of vessels in connection with the financing of new ships and new chartering agreements.”

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.”
