Recent Developments

• In August 2026, ABB secured a contract to supply an integrated power and propulsion package for Allseas’ new 230-meter Grand Tour semi-submersible heavy transport vessel. The system will include four 3.5 MW Azipod propulsion units, a medium-voltage AC power plant, power and energy management systems. The integrated solution enables better vessel handling while it reduces power consumption and improves system operation for offshore wind logistics.
• In June 2026, ABB won a contract from Cochin Shipyard to deliver power and propulsion equipment for their two electric harbor tugs which will enter service in 2027 through India's Green Tug Transition Program. The solution includes ABB’s Onboard DC Grid, PEMS power and energy management system, which optimize battery utilization and drivetrain efficiency. The project shows how marine vessels now use modern power management systems together with electrification technology.
• In March 2026, Exide Technologies expanded its Marine and Leisure portfolio with the EV1920S, a 12.8V, 150Ah lithium-ion battery designed for onboard applications such as navigation, emergency, safety, and comfort systems. The battery system contains Bluetooth technology together with an internal heating element and a power-saving mode and a Battery Management System (BMS) which ensures dependable and cost-effective marine electrical power generation.
• In February 2026, Sunlight Group’s Lehmann Marine subsidiary achieved its biggest contract to provide advanced battery systems for three electric passenger ferries which operate in Hamburg’s Port. The 30-meter ferries operate with a 3.8 MWh modular Lithium Iron Phosphate (LFP) battery system which enables urban maritime transportation at high frequencies while showing the rising use of large-scale marine energy storage systems.
