Lloyd’s Register Awards AiP To CMB.TECH And Damen For Hydrogen Tug Solution


  • Lloyd’s Register (LR) has granted approval in principle (AiP) to CMB.TECH and Damen for a dual-fuel hydrogen solution for four new Damen ASD tugs.
  • This innovative technology aims to significantly reduce emissions and supports the maritime energy transition.

Innovative Hydrogen Technology

CMB.TECH’s innovative dual-fuel hydrogen technology has received approval in principle (AiP) from Lloyd’s Register (LR) for installation on four new Damen ASD tugs. This development marks a significant step in reducing maritime emissions.

Compliance and Specifications

The dual-fuel hydrogen ASD Tugs 2812 FF-H2, with an 80-tonnes bollard pull, comply with the stringent IMO Tier III and EU Stage V standards. These tugs will feature four high-speed dual-fuel hydrogen engines designed to minimize NOx and CO2 emissions, along with modular storage systems for compressed hydrogen. Each tug will carry up to 16 hydrogen bottles, storing a total of 736 kg of pressurized hydrogen at 350 bar.

Fuel Flexibility

Although primarily running on hydrogen, these tugs can switch to traditional fuel if hydrogen is unavailable, and they can operate on 100% traditional fuel if necessary. They are equipped with a total of 160m³ fuel holds.

Previous Collaborations

This collaboration between Damen and CMB.TECH builds on their previous work, such as the development of the Elevation Series, a series of Commissioning Service Operations Vessels (CSOV) powered by dual-fuel hydrogen generator sets, for CMB.TECH’s subsidiary Windcat.

Shared Vision and Commitment

Vincent Maes, Damen Area Sales Manager Benelux, expressed delight in continuing the partnership with CMB.TECH, emphasizing their shared commitment to the maritime energy transition and the goal of making ports and the world greener.

Expanding Hydrogen-Powered Fleet

Alexander Saverys, CEO of CMB.TECH, highlighted the importance of this contract in expanding their hydrogen-powered vessel portfolio, noting that these tugs are ideal for decarbonizing port operations and creating demand for green hydrogen production globally.

Recognition and Support

Andy McKeran, Lloyd’s Register Chief Commercial Officer, praised the cost-effective decarbonization solution provided by CMB.TECH’s dual-fuel hydrogen technology and commended Damen and CMB.TECH for their innovative design. He reaffirmed Lloyd’s Register’s commitment to supporting the maritime energy transition through classification and advisory services.

Celebration and Future Prospects

The collaboration and AiP were celebrated on May 23rd at Albwardy Damen in Sharjah during the 27th International Tug & Salvage (ITS) Convention in Dubai.
