A shipyard in Indonesia has started constructing a fully electric tug as part of a Singapore-backed project to cut emissions from ship manoeuvring
PaxOcean Batam, in Indonesia, has laid the keel of what will become a battery-electric tugboat with an expected bollard pull of 50 tonnes when it is completed in Q1 2026. This project is part of the Coastal Sustainability Alliance (CSA) activities in Singapore and Indonesia to reduce emissions from harbour operations, which includes introducing zero-emissions towage.
CSA, led by Kuok Maritime Group (KMG) celebrated laying the keel for this PXO-ACE-1 tugboat on 5 February as the alliance also launched its first fully electric supply boat.
This project is backed by the Maritime and Port Authority of Singapore (MPA) to attain its goal of minimising emissions from port and marine activities, and is supported by the MPA Maritime Innovation and Technology Fund.
Once the hull of this electric tug is built, it will be mobilised to Singapore for the rest of its assembly. It will then be commissioned, its technology tested and will undergo sea trials before delivery.
Pacific Workboats will operate this vessel, which will be classed by Bureau Veritas and become the first battery-electric harbour tug to operate in Singapore.
PXO-ACE-1 electric tug will incorporate advanced technologies for propulsion, energy storage and battery management systems.
Product development is supported by digital twin models developed by CSA’s research collaborators to ensure this electric tug meets operational requirements within the Port of Singapore.
Also on 5 February, CSA celebrated the launch of its first fully electric supply boat as part of the MPA’s drive for energy-efficient methods of supporting shipping within the nation’s territorial waters.
This PXO-EXL-1 electric supply boat will be dual-classed by Bureau Veritas and RINA and will be ready for sea trials and operations near the end of this year. It was designed with operational insights from harbour craft owners to deliver up to 40 tonnes or 60 pallets, with range extension for remote deliveries to optimise deliveries and reduce marine traffic.
CSA said its efficient hull design and optimised marine logistics mean this “vessel can achieve 60% energy savings over a conventional lighter making multiple trips, providing significant cost and carbon emissions reduction for the industry.”
It will have an energy storage system, a battery management package and a back-up generator set prepared to use zero-carbon fuels when they are available.
CSA will bring together international shipping agencies to explore off-taking arrangements and trial the electric supply boat after its completion and commissioning.
“Today, we witnessed the fruits of industry and researchers’ partnerships and collaboration in driving maritime decarbonisation, and advancing energy-efficient solutions for maritime Singapore,” said MPA’s assistant chief executive for industry and transformation, Kenneth Lim. “MPA is committed to working with industry partners such as CSA to achieve Singapore’s sustainability and decarbonisation goals.”
CSA chair and PaxOcean Group chief executive and managing director, Tan Thai Yong, said the launch of the PXO-EXL-1 e-supply boat “is a testament to our commitment to decarbonising Singapore’s coastal logistics ecosystem.”
He said it demonstrates what CSA can achieve when industry players, researchers and regulators come together to innovate and collaborate.
“The launch of this vessel, together with the keel lay of the PXO-ACE-1 electric tug, bring us closer to achieving a green and operationally efficient maritime sector.”
