NG-20000X Self-propelled jack-up

Future-proof Wind Turbine Installation


The NG’s are a series of multi-purpose self-propelled jack-ups capable of undertaking autonomous transit and positioning offshore.

As the largest self-propelled installation jack-up in the market, the NG-20000X is intended for the future-proof, high end installation works of wind turbines and XL monopile foundations.

The NG-20000X is intended for use in water depths of up to 70 m in a harsh North Sea type of environment. This unit is equipped with well-balanced DP2 capability and a VSD driven jacking system, providing a controlled ramp-up / ramp-down, speed & torque control, for frequent, fast and secure jacking operations. The main feature of the unit is the telescopic leg crane with a capacity of 2,500 t @ 30 m at ± 124 m hook height above main deck or 1,250 t @ 47 m at ± 158 m hook height above main deck.
