Damen Shipyards has secured a contract to construct four fuel-flexible azimuth stern drive tugboats utilizing CMB.TECH's hydrogen combustion technology for emission reduction in port operations. The tugboats are designed to be future-proofed and environmentally friendly, meeting the escalating pressure on tug owners to lower their environmental impact and comply with stringent emissions regulations like IMO Tier III and EU Stage V. While batteries are considered for emission reduction by some, alternative fuels like hydrogen are sought to provide additional power, extend range, and offer operational flexibility between ports. The ASD Tug 2713 FF-H2 design integrates hydrogen fuel to eliminate CO2, NOx, SOx, and particulate matter emissions, exceeding regulatory standards. CMB.TECH's focus on hydrogen integration in vessels includes a dual-fuel system with high-speed engines burning hydrogen in tandem with diesel, significantly reducing CO2 emissions without compromising performance. The vessels also feature underdeck compressed hydrogen storage and robust safety measures to address potential risks. The contract for four ASD 2812 FF-H2 tugs represents a pivotal step in decarbonizing port operations, with each tug equipped with dual-fuel hydrogen engines optimized for emission reduction and compliant with stringent regulations. These vessels are poised to drive demand for green hydrogen production and set a new standard for sustainable maritime operations.
