During the last 17 years in the offshore wind market, we have developed our FOB SWATH semi-submersible vessels. SWATH: Small Waterline Area Twin Hull. Our aim is to have the best personnel and vessels. We provide safety, responsibility, experience, flexibility, 24-hour service, approved by DOC, ISO 9001, 14001, 45001, Achilles, Environmental PoliciesGDPR, Danish Maritime Authority and DNV requirements. 


The lower hulls are narrow and sharp and cuts through the waves at high speed. The pitch, roll and slamming are reduced due to the vessel's construction with great distance from seawater to water deck, and with the four movable foils.


In semi-submerged position the movements are considerably reduced, and avoid air intake in the propulsion units. The automatic movable foils, assist with safe and comfortable operation in rough sea.


The vessels special patented bow fender with movable clams used on the outside of the turbines docking poles, allows the vessel's bow to be pushed sideways, holds the vessels secured in correct position, reducing the forces against the docking pole(s) and vessels bow, all making it possible for our vessels to work up to 2 m. significant wave heights.


  1. The fuel consumption for FS 8, 9 and 10: 20 knots 375 l/h, 25 knots 475 l/h, 27 knots 675 l/h. Max speed for FS 8 = 28 knots, FS 9 & 10 = 33 knots and if one propulsion unit should fall out, the vessel continues with 25 knots.
  2. The increased speed of our vessels with a length of 32.5 m., save time compared with our 25 m. vessels. Both vessels sailing the same distance, use about the same fuel consumption.
  3. With the protected waterjets, the vibrations whilst staying against the "landings" and damages during sailing is minimized.
  4. Acceleration in accordance with the High-Speed Code 2000, vertical acceleration under 1 G, lowest sea sickness index - 0.75 to 1.25, comfortable seating and sound level below 60 decibels.
  5. All our 32.5 m. vessels have Dynamic Positioning (DP), used among others while stand bye and receiving and delivering fuel.
  6. Extra bunker capacity allows the vessels to stay offshore for longer periods.
  7. Free deck area up to 80 m².
  8. Our vessels can carry 24 to 55 Industrial Personnel (IP). We may provide vessel(s) for 12 IP with single cabins, plus 12 for day sailing.
  9. From Cat mode to semi-submersed mode and vice versa, takes about 3 minutes.
  10. During repair and maintenance, another Fob Swath vessel may substitute.
  11. Marine Evacuation System (MES) with slides.
  12. The special rescue net allows to save persons from the sea with one deck man on main deck.
  13. The vessel's hydraulic gangway and the cargo crane, operates safe and easily.
  14. In stock with considerable spare parts and complete engines and gears.
