- Dual-Rotor Pioneer: OceanX’s Unparalleled Wind Harvesting Design
On the V-shaped tower, two main engines are equipped with parallel impellers, covering a sweeping area exceeding 52,000 square meters—comparable to the size of seven standard football fields. With the impeller blades’ tips a mere 5 meters apart, this pioneering design optimizes impeller pitch and wind efficiency while leveraging the V-shape of the tower. It ensures impeller safety and enhances both wind capture and structural stability.
Upon startup, the impellers rotate in opposite directions, enhancing wind speed in the central area and boosting electricity generation from air kinetic energy by 4.29% compared to a single, large turbine with an equivalent swept area.
In the context of the entire wind farm, longer blades on a single turbine can significantly affect the turbine downstream. OceanX employs two small-sized wind turbines, leveraging the coupled vortex effect from counter-rotation to mitigate efficiency losses across the farm.
- Downwind Mastery: OceanX’s Single-Point Mooring Showcases Cutting-Edge Innovation
OceanX utilizes a downwind design, alleviating tower headroom constraints for the blades, allowing greater movement, and enhancing the unit’s power generation efficiency through flexible and efficient wind energy capture.
In the face of extreme typhoon conditions, floating wind turbines must be designed to withstand 360° typhoon loads from the outset to ensure stability and safety. OceanX employs a single-point mooring system, which allows the platform to adaptively yaw with the typhoon’s direction. This ensures that the wind turbine consistently faces the incoming wind, regardless of the typhoon’s path.
In the mooring system, to withstand forces equivalent to a level 17 typhoon, the turret’s high-precision slewing bearings must offer exceptional load-bearing capacity and superior underwater sealing. To guarantee OceanX’s stable maritime operation, Mingyang has meticulously assembled the turret system, adhering to stringent standards and precision demands.
Data reveals that the single-point mooring solution reduces the ultimate load on the support structure by 40%, significantly improving the wind turbine’s safety and stability in typhoon conditions. This technology’s implementation boosts the standardization and efficiency of onshore operations for marine and engineering equipment.
OceanX is also capable of managing total health of the turbine to optimising power generation efficiency and lowering the maintenance cost thus finally cut down Levelized Cost of Energy (LCOE) under different environmental conditions.
- From MW Giants to Deep-Sea Pioneers: Mingyang’s Unceasing Quest for economical offshore wind power
In April 2020, the 1:10 scale prototype of the OceanX dual-rotor floating wind turbine platform was launched in Lake Quarry, Germany. By October, it had completed a two-month offshore operation in the Baltic Sea, enduring tests equivalent to 72m/s winds and 30-meter waves, and earned a feasibility certificate from DNV.
Mingyang has pushed the boundaries of offshore wind power technology, from typhoon-resistant wind power to large offshore megawatt units, and now to the navigation of deep-sea floating turbines. The latest advancements in deep-sea floating wind power are setting new standards for human exploration of the ocean, while decreasing the cost per kWh to make the offshore wind more affordable.
As a leader in global clean energy innovation, Mingyang is committed to driving breakthroughs in marine energy technology. It aims to lead industry innovation, expedite sustainable offshore wind development and facilitate the green transmission globally.
