Hydrogen-Powered Tugs: CMB.TECH and Damen Receive Approval for Innovative Design


Lloyd’s Register (LR) has granted CMB.TECH and Damen an approval in principle (AiP) for their hydrogen solution, set to be installed on four new Damen ASD tugs. This marks a significant advancement in the push for greener maritime operations.

Dual-Fuel Hydrogen ASD Tugs 2812 FF-H2

Specifications: The dual-fuel hydrogen ASD Tugs 2812 FF-H2, boasting an 80-tonne bollard pull, comply with the strictest IMO Tier III and EU Stage V standards.

Engines: Equipped with four high-speed dual-fuel hydrogen engines, these tugs aim to minimize NOx and CO2 emissions.

Storage: The vessels feature modular storage systems for compressed hydrogen, ensuring safe storage below deck. Each tug can carry up to 16 hydrogen bottles, storing a total of 736kg of pressurized hydrogen at 350 bar.

Operational Flexibility

While primarily running on

hydrogen, these tugs can switch to traditional fuel if hydrogen is unavailable. They can also operate entirely on traditional fuel if needed.The tugs have a total of 160m3 fuel holds.

Previous Collaborations and Projects

Damen and CMB.TECH have previously collaborated on the Elevation Series, a series of Commissioning Service Operations Vessels (CSOV) powered by dual-fuel hydrogen generator sets, built for CMB.TECH’s subsidiary Wind Cat.

Statements from Key Figures

Vincent Maes, Damen Area Sales Manager Benelux states “We are delighted once again to be working with CMB.TECH. Our two family-owned companies share the same long-term view and commitment to the maritime energy transition. We’re looking forward to continuing our collaboration and developing the next steps to make our ports – and our world – a greener place.”

Alexander Saverys, CEO of CMB.TECH says “This contract marks another very important step in the development of our hydrogen-powered vessel portfolio. ASD tugs are ideal assets to start the decarbonization of port operations. With our hydrogen tugs, every port in the world will now be able to lower its carbon emissions and create demand for green hydrogen production.”

Andy McKeran, Lloyd’s Register Chief Commercial Officer states “The AiP for CMB.TECH’s dual-fuel hydrogen technology represents a cost-effective decarbonization solution for tugs and will provide Damen’s new ASD tugs with dual-fuel hydrogen propulsion to greatly reduce the vessels’ emissions profile. Lloyd’s Register congratulates Damen and CMB.TECH for the successful realization of this innovative design and will continue to provide classification and advisory services that help to drive forward the maritime energy transition.”

Ceremony and Recognition

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