en.Wedoany.com Reported - Sweden's Berg Propulsion has secured a contract to supply propulsion systems and electrical integration technology for two fully electric harbor tugs being built under India's "Green Tug Transition Program."

The two tugs are currently being built by the Mumbai-based KMEW Group on behalf of India's Ministry of Ports, Shipping and Waterways and are expected to enter service in the fourth quarter of 2027, pending regulatory approvals. The program aims to deploy 50 green tugs across major Indian ports by 2030, as part of supporting the country's goal of achieving net-zero emissions by 2070.

Berg Propulsion's scope of supply includes electric motors, contra-rotating L-drive thrusters, electrical system integration, and intelligent propulsion control systems, along with overall project management support. Designed by Navnautik, the tugs are each 33.55 meters long with a bollard pull of 60 tonnes. They will be primarily powered by lithium-titanate-oxide batteries, equipped with dual diesel generator sets for backup power.

The Swedish propulsion system supplier stated that the compact design of its propulsion system helped reduce the switchboard room footprint by approximately 40%, freeing up space onboard. Amrita Singh, New Sales Account Manager at Berg Propulsion, said: "By working closely with Navnautik, KMEW, and the customer, we managed to reduce the switchboard room size by about 40% by placing most of the propulsion equipment at the tug's aft." She added that the company has been integrating electrical systems, engines, and thrusters on hybrid electric vessels for years, and this experience made the transfer of relevant knowledge to the fully electric tug design straightforward.

Aniruddha Sen of Navnautik stated: "Considering the premium on space onboard, the arrangement of the electric drive train can be challenging for any vessel designer." He mentioned that the compact nature of Berg Propulsion's integrated components provided significant flexibility for incorporating them into the general arrangement.
