Bureau Veritas Marine & Offshore (BV) has announced the delivery of Eon – the first fully electric harbor tug in Singapore and Southeast Asia. Built by PaxOcean and owned by Kuok Maritime Group (KMG) under the Coastal Sustainability Alliance (CSA), Eon represents a major advancement in the region’s transition toward cleaner and more efficient harbor craft.
Following the successful delivery of Voltai (PXO-ACE-1), the first fully electric supply vessel built by PaxOcean in February 2024, Eon (PXO e-tug) marks another milestone for the shipbuilder. The 29m tug, with a 50-ton bollard pull, features an integrated electric propulsion system from ABB. It is powered by a 3MWh lithium titanate oxide (LTO) battery pack connected to ABB’s energy management and DC grid systems. This configuration enables efficient battery integration, reduces energy conversion losses between power sources and onboard loads, and optimizes drivetrain efficiency while extending the vessel’s operational range per charge.
BV works with the CSA and KMG to class these zero-emission vessels, which are among the first and largest locally designed electric harbor craft intended for operation in Singapore’s coastal waters. Eon has been assigned BV’s Battery System Notation, reflecting its fully electric propulsion architecture.
In Singapore, BV has been playing a key role in advancing maritime electrification. Earlier projects with Penguin International, Yinson and Pyxis reflect the growing ecosystem of industry players committed to cleaner maritime operations.
“Bureau Veritas congratulates Kuok Maritime Group, PaxOcean and the Coastal Sustainability Alliance on this important achievement,” said Drago Pinteric, vice president, M&O South East Asia, Bureau Veritas. “We remain committed to supporting the maritime industry in deploying clean technologies that will shape a more sustainable and resilient maritime future for Singapore and Southeast Asia.”
