Each vessel will be equipped with the following from aft to bow: two azimuth propulsion thrusters propulsion, a retractable azimuth thruster, a tunnel thruster, and a combined retractable azimuth and tunnel thruster. The scope of supply features also Brunvoll’s Propulsion and ThrusterControl system, BruCon PTC.

The azimuth propulsion thrusters are equipped with Brunvoll’s latest energy-efficiency innovation, the DL1-nozzle, also known as the “Dragless”. While traditional nozzles experience an efficiency drop at transit speeds, the DL1 maintains favourable hydrodynamic characteristics across a broader operating range. More information about the nozzle and its features is available at Brunvoll DL1, The “Dragless” nozzle.

The vessels are based on VARD’s 4 19 design, with the following main particulars: length of 87.5 meters, beam of 19.5 meters, and accommodation capacity for 120 persons, along with all equipment required for a CSOV.
