As the first CAT‑SWATH dual-mode wind farm service vessel in China, it inherits the hull advantages of a small waterplane area twin hull and boasts versatile application scenarios through dual-mode operation switching. The vessel adopts water-jet as the main propulsion system, paired with a single-handle vector control system, as well as a bow thruster and bow fender bump design. It effectively improves the berthing success rate and operation efficiency during wind turbine boarding tasks, and greatly extends the operational weather window.
