CMB.TECH and Damen partner on four hydrogen-powered tugs

CMB.TECH and Damen are collaborating on hydrogen-powered ASD Tugs. Built by Damen, these vessels use CMB.TECH’s innovative dual-fuel hydrogen technology that will significantly reduce emissions.

The dual fuel hydrogen ASD Tugs 2812 FF-H2, with 80-tonnes bollard pull meet the most stringent IMO Tier III and EU Stage V standards. The vessels will feature four highspeed dual fuel hydrogen engines, designed to minimize NOx and CO2 emissions. They will also have 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.

While these tugs will primarily run on hydrogen, they’re equipped to switch to traditional fuel if hydrogen isn’t available and can operate on 100% traditional fuel if needed. The tugs feature a total of 160m3 fuel holds.

The collaboration agreement for the first four vessels was signed on 23 May at Albwardy Damen in Sharjah during the 27th International Tug & Salvage (ITS) Convention in Dubai.

Earlier that day, classification society Lloyd’s Register presented CMB.TECH and Damen with an approval in principle (AiP) for the hydrogen solution that will be installed in the tugs.

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.

Damen and CMB.TECH have previously cooperated on the development of a series Commissioning Service Operations Vessels (CSOV) which are powered by dual-fuel hydrogen generator sets—the Elevation Series that Damen is building for CMB.TECH’s subsidiary Windcat.
