SMW 2025: Coastal Sustainability Alliance inks LOIs for Singapore’s largest electric supply boat

The Coastal Sustainability Alliance (CSA), an industry collaborative effort led by Kuok Maritime Group (KMG), on Wednesday (26 March) signed two Letters of Intent (LOIs) on Day 2 of the Accelerating Digitalisation and Decarbonisation Conference at Singapore Maritime Week (SMW 2025). 

The first focused on prioritising using Singapore’s largest electric supply boat, PXO E-Supply Boat Voltai, by key ship agencies during an upcoming trial and the second focused on developing a multi-modal, multi-site marine charging infrastructure. 

These partnerships marked a significant milestone in advancing the adoption of e-vessels and supporting infrastructure.

“Milk Run” Trial with Shipping Companies for E-Supply Boat Adoption

KMG has signed an LOI with seven major ship agencies and one chandler: GAC Singapore, Horizon Shipping Agencies, Inchcape Shipping Services, Johnasia Shipping, RMS Marine & Offshore Service, Sinoda Shipping Agency, and Wilhelmsen Port Services — to utilise the services of the PXO E-Supply Boat Voltai for deliveries to seagoing vessels in a one-year trial.

The trial will prioritise lightboat operators making multiple deliveries, known as a “milk run”, to improve operational efficiency, lower carbon footprint, reduce marine traffic congestion and lower costs associated with operating electric vessels.

The trial addresses the growing pressure on merchant shipowners to reduce Scope 3 emissions, offering a commercially viable pathway for greener supply chain solutions. Each E-Supply Boat  trip is expected to cut 0.5 metric tons of Scope 3 greenhouse gas (GHG) emissions per arrival of a merchant ship at the Port of Singapore. 

As the marine logistics industry pivots towards net-zero goals, the electrification pathway can result in an estimated reduction of 9,000 metric tonnes (mt) of GHG emissions per month across 600 daily trips made by conventional supply boats. The findings from the trial will influence the development of future PXO E-Supply Boats, ensuring that they align with industry needs while advancing Singapore’s decarbonisation goals.

Multi-Site, Multi-Modal Marine Charging Infrastructure

KMG has signed another LOI with Singapore and international companies: BeeCharge Innovation Group, Jurong Port, Pyxis, RExus Bioenergy, SP Mobility, and Wilhelmsen Ships Service – to provide charging infrastructure and facilities to support the appointed operator of the PXO E-Supply Boat Voltai during the “milk run” trial. 

This partnership will feature a multi- modal and multi-location approach featuring various charging infrastructure, including shore-based charging at key waterfront sites, and mobile charging powered by solar energy for on-demand needs. As the charging infrastructure will operate on a common technical standard, it will be critical in accelerating MaritimeSG’s green transition by enabling efficient charging turnaround for e-vessels and minimising operational downtime.

Mr Tan Thai Yong, Managing Director and CEO, PaxOcean Group and Chairperson, CSA, said: “The commitment by leading ship agencies and a chandler to prioritise the hiring of the PXO E-Supply Boat Voltai marks a fundamental shift in maritime logistics.”

“Traditionally, supply boat operations have been conducted point-to-point, leading to inefficiencies and increasing emissions. Implementing the ‘milk run’ model consolidates multiple deliveries into optimised routes, benefiting all stakeholders by reducing unnecessary trips, lowering operational costs, and significantly cutting emissions.”

On the charging partnership LOI, he added, “By bringing together various site owners and charging partners, we envision concurrent efforts contributing to Singapore’s electric charging infrastructure along the coastline, eventually extending beyond our PXO vessels’ operating bases.

Over time, we hope to see more public charging infrastructure deployed strategically and decisively along Singapore’s shoreline to support operations in the Western and Eastern anchorages.”

Note: SMW 2025 will feature a public showcase of the PXO E-Supply Boat “Voltai” on 29 March. Complimentary tickets are available here.

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.”
