Hybrid SES Crew Transfer Vessel

Hybrid air-assisted Crew Transfer Vessel (CTV) is designed to enhance offshore wind operations by combining proven catamaran hull stability with air cushion technology. Integrated fore and aft lift modules actively manage vessel trim, reduce hull resistance, and improve pitch damping, delivering a smoother ride and more stable docking in dynamic offshore conditions.

Constructed entirely from marine-grade aluminium, the 24-metre vessel offers a balance of strength, weight efficiency, and corrosion resistance. Its configuration supports the safe and comfortable transfer of up to 40 technicians and 4 crew, with onboard systems designed for reliability and rapid turnaround at sea.

Key Features:

  • Surface Effect Ship (SES) Technology: Twin air cushion chambers (fore and aft) generate lift and reduce hydrodynamic drag, allowing higher transit speeds with lower fuel burn compared to conventional hulls.
  • Enhanced Ride Comfort: Active trim control and pitch damping reduce vertical accelerations, improving crew comfort and safety.
  • Optimised Docking Stability: Air cushion assist improves contact stability against boat landings, even in moderate sea states, reducing risk during personnel transfer.
  • Future-Ready Efficiency: Designed for hybrid power integration and high-throughput transfers to meet expanding

Optimised for speed, comfort, and environmental responsibility, the design reduces slamming impacts, enhances fuel efficiency, and expands the vessel’s weather-operable window. Ideal for operators looking to minimise crew fatigue and maximise turbine uptime in growing offshore wind fields.
