The tugboat and workboat industry is undergoing a significant shift towards adopting alternative fuels and technologies to reduce vessel emissions and contribute to a greener maritime sector. Various fuels such as methanol, batteries, and potentially hydrogen are being considered, each with its own benefits and challenges. Damen Shipyards, a key player in this transition, is designing vessels with a focus on alternative fuels like methanol and batteries, with provisions for future adaptation to hydrogen. The industry acknowledges the complexity of decarbonization, emphasizing the importance of considering multiple criteria such as energy source, emissions implications, and operational requirements when choosing fuels. In the absence of a one-size-fits-all solution, strategies like biofuels, SCR units, and flexible fuel options are being implemented to achieve significant emissions reductions and comply with environmental regulations. As the industry awaits the maturation and wider availability of alternative fuel technologies, current solutions like biofuels and SCR units offer an effective interim approach towards sustainability and emissions reduction.
