ABB has secured a contract from Cochin Shipyard Limited (CSL) to provide integrated power and propulsion systems for two electric harbour tugs being built under India’s Green Tug Transition Programme (GTTP). The vessels, scheduled for delivery in 2027 to Polestar Maritime, will operate at Jawaharlal Nehru Port Authority (JNPA), the country’s largest container port.
The project marks a significant milestone in India’s efforts to decarbonize port operations and modernize maritime infrastructure through cleaner technologies. The GTTP aims to gradually replace conventional diesel-powered harbour tugs with environmentally sustainable alternatives through a phased implementation extending to 2040.
ABB’s scope of work includes electrical systems, propulsion technology, automation solutions and digital capabilities designed to maximize vessel efficiency and operational reliability. At the center of the solution will be ABB’s Onboard DC Grid™ platform and PEMS™ power and energy management system, enabling intelligent utilization of onboard battery energy across varying operational loads.
The advanced power architecture is expected to optimize energy consumption, improve drivetrain performance and enhance operational flexibility. The modular design also allows seamless integration of battery storage systems while extending vessel operating range between charging cycles.
To further support vessel reliability, ABB will deploy its ABB Ability™ Remote Diagnostic System for Marine, providing continuous condition monitoring and remote troubleshooting capabilities. The digital platform will help operators identify potential issues before they impact performance, minimizing downtime and improving operational efficiency.
Jose VJ, Chairman and Managing Director of Cochin Shipyard Limited, emphasized the strategic importance of selecting an experienced technology partner for the project. “Electric harbour tugs require sophisticated integration of propulsion, automation and energy management systems. ABB’s global experience and proven marine technologies provide the confidence needed to deliver vessels that demonstrate both performance and sustainability,” he said.
Rune Braastad, President of ABB Marine & Ports, said the project reflects India’s growing commitment to cleaner maritime operations. “The Green Tug Transition Programme represents an important step in reducing emissions from port activities. We are proud to contribute technologies that support India’s maritime sustainability objectives while enhancing operational performance,” he said.
ABB has maintained a presence in India for more than 75 years and continues to support maritime innovation across the region. The company has also supplied electrification technologies for vessels in Singapore, South Korea and Japan, reinforcing its position as a key contributor to the global transition toward low-emission marine transportation.
