  1. Platform Design

    The clever thruster lay out with 4 identical azimuthing thrusters results in unrivalled maneuverability and station keeping. In addition this lay-out significantly reduces fuel consumption, noise levels, and investment compared to traditional thruster lay-out. Maintenance and stock keeping is made easier since all units are identical, including the electric drive train.

  2. Carbon neutral options

    Power generation is by means of IMO Tier-III / EPA Tier-IV diesel generators which are supported by a battery pack. The diesel-electric system is designed to operate safely with closed bus-ties. This makes it safely possible to have less engines running, resulting in reduction of fuel oil consumption and harmful emissions with up to 20% and less maintenance.
    In addition to the already highly efficient performance, the carbon footprint can further be reduced by using bio-diesel. As an option the vessel may even be delivered to run on bio-methanol. All this brings carbon-neutral operations to reality.

  3. Comfort

    Damen SOV’s are designed as the perfect tools for their task, but for that you need a well-rested and focused crew. In our design we want the crew to instantly feel at home without having to spend too much time on trying to find their way. Especially when it is your first time onboard. We have focused on creating a separated design between the work and leisure areas. The leisure areas and cabins are designed with warm and soft materials, playful elements and nice colors to unwind comfortably after a hard day of work.

Proving the designs performance

Innovations in the design and design process of this vessel are:
• Seakeeping analysis of systematic variations of hull design and dimensions, verified by tank tests, resulting in high natural roll period and low roll motions in North Sea conditions. More access, more comfort.;
• Balanced, and low lateral wind profile, as well as shallow draught contribute to reduced power demand while station-keeping in beam-on conditions;
• Focus on high-speed transits between turbines while remaining in DP, as has been demonstrated by model tests in challenging environmental conditions;
• The actual controllers of DP and motion-compensated gangway systems, and the vessel’s seakeeping characteristics are being tested in simulated environmental conditions in unison in a hardware-in-the-loop (HIL) test. This will ensure smooth setting-to-work and operational performance from day 1;
• Development of a vessel simulator based on the HIL-test setup, will produce a “digital twin” to the vessel and access system. Prior to charter award, this enables the owner to offer to clients an assessment of operational access performance in client-specified environmental and site conditions much more accurately than is possible with just vessel RAO’s;

These innovations are now being realised in a vessel concept which, because of it’s bench-marking high operability, lead to more, and safer access to the wind energy sector, thereby contributing to lower cost of energy.



All Damen vessels benefit from knowledge gathered during ongoing research programmes within the Group. Damen works alongside world-renowned research institutes such as Delft University of Technology, Maritime Research Institute Netherlands (MARIN) and the Netherlands Organization of Applied Scientific Research (TNO), as well as other reputable universities and leading maritime companies.
