Belgium-based shipping company EXMAR on Wednesday (10 March) received an Approval in Principle from Lloyd’s Register (LR) for its ammonia (NH3) fuelled 40,000 m3 Midsize Gas Carrier design, it says.

Jiangnan Shipyard was responsible for the ship design while Wärtsilä Gas Solutions provided all input for the ammonia fuel gas supply system.

The Novel Technology Evaluation included an overall examination of fundamental aspects of the design and compliance with LR’s Rules and Regulations for the Classification of Ships and for the Carriage of Liquefied Gases in Bulk (for Gas Ships), incorporating the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code).

A risk assessment was also conducted, using EXMAR’s extensive knowledge and experience of operating Ammonia carriers, to ensure that risks arising from the use of ammonia fuel affecting persons onboard, the structural strength or the integrity of the ship are addressed in accordance with LR’s ShipRight Procedure for Risk-Based Designs (RBD). This included a Hazard Identification (HAZID) study which led to the Approval in Principle.

Ed Fort, LR’s Global Head of Engineering Systems, said:

“Lloyd’s Register is immensely proud to have awarded EXMAR Approval in Principle for its ammonia-fuelled Medium Gas Carrier, demonstrating our commitment to shipping by supporting clients with novel designs. This is a significant milestone in progressing alternative fuels for shipping’s transition to zero-carbon, proving the possibility of the use of ammonia as a fuel and how adaptable the fuel is to gas carriers, especially if carrying ammonia as cargo.”

Jens Ismar, Executive Director Shipping at EXMAR, said:

“This approval in principle is an important milestone in the process of developing low CO2 emission gas carriers. EXMAR continues its steps towards further innovation and decarbonisation by demonstrating the possibility of using ammonia as fuel onboard gas carriers. This follows EXMAR’s initiative of introducing LPG as a fuel in 2012 which is being implemented on our world’s first order of two dual fuel VLGCs currently under construction.”

“This work, together with EXMAR, Jiangnan and Lloyd’s Register for an Ammonia fuelled MGC, is an important step along the road towards decarbonising the shipping fleet. During the AiP process, we have provided the details for the Ammonia fuel system developed by WGS and also jointly conducted required studies for evaluating the readiness of the systems. We are proud to have played our part in having the AiP granted from Lloyd’s Register,” said Kjell Ove Ulstein (Director Sales and Marketing) at Wärtsilä Gas Solutions.

Hu Keyi, Chief of Corporate Technology of Jiangnan Shipyard, said:

“Jiangnan is continuously making efforts to find practical solutions for carbon natural and zero carbon transportation. Jiangnan, as leading gas carrier shipbuilder in China, has cooperated with LR and WGS, to deliver gas fuelled gas carriers to reputable ship owners, like EXMAR. We believe this project of ammonia-fuelled Medium Gas Carrier is not only a low CO2 emission ship, but it will also be a significant landmark on the roadmap of IMO 2050.”

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.”
