A recent development in California sees the approval of a conversion kit that enables owners of port and offshore support vessels to switch their propulsion systems to electric, paving the way for a greener maritime industry. Supported by funding from the Clean Off-Road Equipment Voucher Incentive Project (CORE), vessels like tugs, offshore support vessels, and harbour craft can now benefit from reduced emissions and lower operating costs. Twin Disc and Palmer Johnson Power Systems' electric propulsion system conversion kit, approved by the California Air & Resources Board (CARB), stands out for its contribution to environmental initiatives and sustainable practices. The validation of this technology by CARB highlights its compliance with stringent emissions standards. The upcoming Riviera conferences in Amsterdam and Bergen will provide a platform to address critical environmental issues in the maritime sector, focusing on achieving low-carbon and zero-emissions shipping through innovative solutions and strategies.
