Singapore’s first fully electric tug has reached a significant project milestone, with the vessel completing commissioning ahead of its expected deployment in April 2026. Built by PaxOcean Group, a subsidiary of Singapore-based Kuok Maritime Group, the 50-ton bollard pull PXO-ACE-1 features an integrated electric propulsion system from ABB for efficient, emission-free harbor operations.
With the Maritime and Port Authority of Singapore requiring all new-build harbor craft to be fully electric or compatible with B100 biofuels or net zero fuels by 2030, the new vessel marks the first step toward the electrification of the city-state’s 1,600-plus harbor vessels, improving local air quality, reducing onboard noise and vibrations and creating healthier working environments for crew.
As the core of PXO-ACE-1’s power and control system, ABB’s Onboard DC Grid with PEMS (power and energy management system) will enable the e-tug to make optimal use of its 3MWh battery pack to support wide variations in power demand, including instant high torque. The Onboard DC Grid facilitates battery integration and reduces the number of energy conversions between different sources and loads, thereby optimizing drivetrain efficiency while extending operating range per battery charge.
“Developing Singapore’s first fully electric tug is a significant achievement and an important step in advancing maritime decarbonization,” said Tan Thai Yong, managing director and chief executive officer of PaxOcean Group. “ABB has supported us as the systems integrator on this project, contributing their experience in battery-powered vessels to the integration of the power, propulsion and bridge systems on board this e-tug – a first of its kind. The operational integrity, safety and performance of this vessel depend on reliable systems and effective integration, and ABB has delivered on both. We look forward to seeing PXO-ACE-1 in operation.”
Olli Tuunainen, local business line manager, Singapore in ABB’s Marine & Ports division, added, “We are proud to be part of this groundbreaking project for Singapore, supporting the world’s maritime capital in its journey toward fully electric harbor operations. Tugs are among the industry’s leading candidates for full electrification, given their operational profile, relative proximity to charging infrastructure, and the operational benefits they derive from an electric drivetrain, including instant power and enhanced crew comfort. We believe that this project will provide a blueprint for further electrification in Singapore and throughout Asia.”
