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 human qualities and vessels. We provides safety, responsibility, experience, flexibility, 24-hour service, approved by DOC, ISO 9001, 14001, 45001, Achilles, Environmental Policies and GDPR regulations.


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 great distance from seawater to water deck, and with the four foils and interceptors.


In semi-submerged position the movements are considerably reduced, which allows the vessels to stay comfortable at the sites in rough weather for longer periods.


The vessels special patented bow fender with removable clams used on the outside of the turbines docking poles, enable the vessel's bow to be pushed sideways, hold the vessels in the correct position and vessels to work in 2 m - significant wave heights. These improvements have been used with great success on all our vessels since 2016. In addition, our bow fender with hydraulic suspension reduces the forces against the docking pole(s), the vessels bow and provides "soft landings".


  1. Fob Swath 8, 9 & 10 fuel consumption: 20 knots 375 l/h, 25 knots 475 l/h, 27 knots 675 l/h. Max speed for FS 8 = 31 knots and FS 9 & 10 = 35 knots. If one propulsion unit falls out, she may continue 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 4 protected waterjets, the vibrations whilst staying against the "landings" and damages during sailing is minimized
  4. Maneuvering from 1/3 forward to 1/3 aft within one second. The vessels great manoeuvrability with extra side-trust, assists with safe "landings" and extra utilization days
  5. 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 under 60 decibels
  6. Some of our vessels have the DP system, used among others while refilling turbines generator sets
  7. Extra bunker capacity allows the vessels to stay offshore for longer periods
  8. Free deck area, from 30 to 80 m.2
  9. All our vessels are for 24 "IP" (Industrial Personnel). Some can take up to 55 IP, or as an accommodation vessel for 12 IP, plus 12 IP for day tours
  10. All crew members and IP with accommodation, have single cabins with WC and shower 
  11. From Cat mode to semi-submersed mode, takes about 3 minutes and same for returning to Cat mode
  12. During repair and maintenance, another Fob Swath vessel may substitute
  13. Marine Evacuation System (MES) with slides
  14. The special rescue net allows to save persons from the sea with one deckman on main deck
  15. Vessel's hydraulic gangway operates safe and simple
  16. In stock with considerable spare parts and complete engines and gears
  17. Classed by DNV GL and approved by Danish Maritime Authority
