CSA launches Singapore’s largest electric supply boat, lays keel of fully electric tug

The Coastal Sustainability Alliance (CSA), an industry collaborative effort led by Kuok Maritime Group (KMG), on Wednesday (5 February) marked a significant achievement with the launch of its first fully electric supply boat (e-supply boat) from shipyard to water and keel lay of its first fully electric tug at PaxOcean Batam.  

CSA said these electric vessels are amongst the first and largest local electric harbour craft designed for operations in Singapore’s waters. The e-supply boat is launched ahead of the nation’s goal for all new harbour craft to be fully electric or compatible with net-zero fuels by 2030. 

Mr Tan Thai Yong, Managing Director and CEO, PaxOcean Group and Chairperson, CSA, said: “The launch of the PXO-EXL-1 e-supply boat is a testament to our commitment to decarbonising Singapore’s coastal logistics ecosystem. This vessel demonstrates what CSA can achieve when industry players, researchers, and regulators come together to innovate and collaborate. Together with the keel lay of the PXO-ACE-1 electric tug, these milestones bring us closer to achieving a green and operationally efficient maritime sector.”

Mr Kenneth Lim, Assistant Chief Executive (Industry & Transformation), Maritime and Port Authority of Singapore (MPA), said: “Today, we witness the fruits of industry and researchers’ partnerships and collaboration in driving maritime decarbonisation, and advancing energy efficient solutions for Maritime Singapore. MPA is glad to celebrate the launch of Coastal Sustainability Alliance (CSA)’s first fully electric supply boat and the keel lay of the electric tug, and is committed to working with industry partners like CSA to achieve Singapore’s sustainability and decarbonisation goals.”

The PXO-EXL-1 Electric Supply Boat is capable of cruising at 8 knots in zero-emission operations while maintaining operational reliability. Coupled with an efficient hull design and operationally efficient marine logistics, the vessel can achieve 60% energy savings over a conventional lighter making multiple trips, providing significant costs and carbon emissions reduction for the industry.

Supported under the MPA Maritime Innovation and Technology Fund, the 50T bollard pull PXOACE-1 electric tug incorporates advanced technologies for propulsion, energy storage, and battery management systems. The product development is supported by digital twin models with research collaborators to enhance confidence in an electric tug to meet operational requirements within the Port of Singapore. The tug will be future fuel-ready for zero-carbon fuels.

The CSA will bring together international shipping agencies to explore offtaking arrangements and trial the electric supply boat in the second half of 2025, while the construction of the electric tug is slated to be completed in the first quarter of 2026.
