Over 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 the best vessels. Crew and company provides safety, responsibility, experience, flexibility, 24-hour service, approved by DOC, ISO 9001, ISO 14001, OHSAS 18001AchillesEnvironmental Policies and GDPR regulations.



The lower hulls are narrow and sharp, and she cuts through the waves at high speed. The pitch, roll and slamming are reduced because of the distance from the water level to the water deck and with the four foils and interceptors. 




In semi-submerged position the movements are considerably reduced, which allows the vessels to stay at the site for longer periods.



The bow fender with our special patented clams on the outside of both docking poles, improves safety, allows the vessels to work in 2- m significant wave heights and push the bow fender to the right position. Our system has been tested and used on our vessels with great success since 2016 in the Irish Sea, the North Sea and the Baltic Sea.



  1. Fob Swath 8's fuel consumption: 20 knots 375 l/h, 25 knots 475 l/h and 30 knots 675 l/h
  2. Fob Swath 8's max speed is 32 knots. If one propulsion unit falls out, she continues with 26 knots and may continue her charter until planned docking or replaced by substitute vessel
  3. The increased speed of our 32 m vessels save time compared with our 25 m vessels. Both vessels sailing over the same distance, use about the same fuel consumption
  4. With the 4 protected water-jets, the vibrations whilst staying against the "landings" and damages during sailing are minimized
  5. Manoeuvrability from 1/3 forward to 1/3 aft within 1 second, bow thrusters and water jets gives 7-ton side trust. All assists with safe "landings" and extra utilization days

  7. Some of our vessels have the dynamic position system, used among others while refilling generator sets
  8. Extra bunker capacity allows the vessels to stay offshore for longer periods, and all can refill generator sets
  9. Free deck area, from 30 to 80 m.2
  10. Our vessels are all for 24 "IP" (Industrial Personal), some can take up to 56 "IP", some as an accommodation vessel for 12 "IP" or as a  CTV for 24 "IP"
