WIND FARM SERVICE VESSEL WATERJET PROPULSION

PRECISION AND PERFORMANCE FOR OFFSHORE WIND SUPPORT

Rhoscolyn Head is a 15-meter wind farm service catamaran built for Turbine Transfers Ltd., powered by twin MJP UltraJet 451 waterjets for reliable precision, maneuverability and sustained performance during crew transfers at offshore wind farms.

Rhoscolyn Head was developed to meet the demanding requirements of offshore wind farm service operations, where reliable crew transfer, precision station keeping and consistent performance are critical. Operating in sometimes harsh marine environments around turbine structures and open seas, the vessel must offer responsive thrust, tight handling and efficient travel between ports and offshore locations.

Wind farm service catamarans also face unique challenges including rapid acceleration for transit, stability during transfers onto turbine platforms, and sufficient power to maintain position in varying sea states — all without sacrificing crew comfort and safety.

TWIN ULTRAJET 451 WATERJETS FOR CONTROLLED THRUST AND MANEUVERABILITY

Marine Jet Power supplied twin MJP UltraJet 451 waterjets for Rhoscolyn Head. These high-thrust axial flow units are engineered to deliver dependable power, enhanced maneuverability and precise control — essential features for vessels tasked with crew transfers and wind farm service.

The propulsion layout, combined with quick-shift gearboxes and Scania powerplants, ensures:

• rapid transit to and from offshore facilities
• precise handling in tight quarters and changing sea states
• reliable thrust for holding station during transfers
• smooth acceleration and direction control
• strong performance at operational service speeds
  Waterjet propulsion also offers inherent benefits such as reduced draft, better shallow water access and lower risk of entanglement compared to traditional propellers — key for operations around submerged obstacles and turbine substructures.
