The Castor Initiative has announced that global energy major TotalEnergies has become the eighth partner to the global coalition that is committed to make zero emission shipping a reality, according to Lloyd’s Register (LR) on Friday (2 December). 

The global coalition, which includes MISC Berhad (MISC), LR, Samsung Heavy Industries (SHI), MAN Energy Solutions (MAN ES), the Maritime and Port Authority of Singapore (MPA), Yara Clean Ammonia (Yara) and Jurong Port, was established in January 2020 and its most recent project milestone was the April 2022 memorandum of understanding for a pair of zero emission deep sea tankers vessels.

With TotalEnergies as the Castor Initiative’s latest partner, the multinational coalition has added to its circle of maritime expertise to ensure and support the complete ecosystem required for ammonia-fuelled tankers to operate sustainably and safely. 

As an energy major on a global scale, and its commitment to sustainability, TotalEnergies brings its extensive operational experience to this global alliance to support the maritime industry’s drive to decarbonisation. The experience and expertise of each Castor Initiative partner will be central to the success of the initiative, from conception to project realisation.

Jérôme Cousin, Senior Vice President Shipping, TotalEnergies said: “Among various decarbonized marine fuel alternatives, Ammonia could rapidly become a viable solution in the maritime sector while challenges remain to be addressed, in particular on the safety aspects. We are therefore enthusiastic to join the Castor initiative, one of the most comprehensive and ambitious project dealing with ammonia as a fuel today. As a multi-energy company committed to the energy transition, TotalEnergies will strive to bring its charterer perspective in this consortium of highly reputable industry players.”

MISC President and Group CEO, Captain Rajalingam Subramaniam said: “Thank you TotalEnergies for this great leadership and collaboration towards achieving a common industry goal in shaping another decarbonisation pathway for the maritime industry, in a safe and efficient manner.

We are excited to welcome TotalEnergies to the initiative and look forward to jointly advancing ammonia as a credible and safe zero-carbon maritime fuel. TotalEnergies entering the existing partnership will create an acceleration of the consortium’s efforts toward the common goal of delivering zero-emission deep sea tankers in the near future.”

Kenneth Lim, Assistant Chief Executive (Industry & Transformation), MPA, said: “MPA welcomes TotalEnergies’ participation to the Castor Initiative. The decarbonisation of the fleet and development of green ammonia supply chain and other hydrogen carriers to meet IMO targets will require the commitment of diverse stakeholders across the entire value chain. As the world’s top bunkering hub, Singapore will work closely with the industry to bring in green marine fuel supply chain, through consortiums such as the Castor Initiative and the green and digital shipping corridors, to enable the energy transition.” 

Jurong Port Chief Executive Officer, Terence Seow, said: “Jurong Port looks forward to TotalEnergies’ participation and contribution to complete the supply chain solution needed for ammonia-fuelled tankers to operate safely and sustainably. The consortium will be able to leverage on TotalEnergies’ technical capabilities & operational experience. To support the adoption of zero emission vessels, Jurong Port will work closely with the partners of The Castor Initiative to develop a robust and sustainable ammonia bunkering supply chain in Singapore.”

To meet the International Maritime Organization’s (IMO) 2050 ambitions on halving greenhouse gas (GHG) emissions from 2008 levels, zero-carbon vessels need to enter the world fleet by 2030. This Joint Development Project has been motivated by the partners’ shared belief that the maritime industry needs leadership and greater collaboration if shipping is to meet the IMO’s GHG ambitions.

While ammonia is one of the fuels being considered by maritime stakeholders, the partners also recognise that the shipping industry will need to explore multiple decarbonisation pathways and hope their collaboration will spur others in the maritime industry to work collectively on addressing this global challenge.

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.”
