India’s Cochin Shipyard has awarded ABB a contract to supply power and propulsion systems for two new electric tugboats. Due for delivery to Polestar Maritime in 2027 as part of Phase 1 of India’s Green Tug Transition Program (GTTP), the vessels will operate out of Jawaharlal Nehru Port Authority (JNPA), India’s largest container port, accounting for around 50% of the total containerized cargo volume handled by the country’s major ports

The GTTP aims to transition India’s harbor tug fleet from conventional diesel-powered vessels to greener alternatives in five phases from 2024 to 2040.

Covering electrical, propulsion, automation, and digitalization solutions, ABB’s comprehensive scope of supply will ensure the green tugs’ efficient and reliable operations, aligning with the broader objectives of the GTTP while advancing JNPA’s efforts towards “Green Port” status. ABB’s Onboard DC Grid power system platform and PEMS power and energy management system will form the core of the combined power and propulsion solution, enabling the vessels to make optimal use of onboard batteries to support wide variations in power demand. The modular and highly customizable Onboard DC Grid not only facilitates the integration of energy storage systems but also optimizes drivetrain efficiency and extends operating range per battery charge.

Also part of the ABB scope of supply, the ABB Ability Remote Diagnostic System for Marine will help to keep the e-tugs running reliably and efficiently through condition monitoring and remote troubleshooting.

“Integrating electric propulsion and advanced automation into harbor tugs is a complex engineering undertaking, and selecting the right technology partner was critical,” said Shri Jose VJ, Chairman and Managing Director, Cochin Shipyard Limited. “ABB’s proven systems and deep experience in this space made them the clear choice. We are building these vessels to last, to perform, and to demonstrate that Indian shipyards are ready to lead the industry’s green transition.”

“India’s Green Tug Transition Program represents a decisive step the nation has taken towards reducing emissions from port operations,” said Rune Braastad, president, ABB’s Marine & Ports division. “Being selected to provide the electrical, propulsion, and automation systems for JNPA and Cochin Shipyard’s first electric tug vessels as per India’s GTTP program reflects the trust that India’s maritime sector has placed in ABB’s technology and our long track record in marine electrification.”
