Floating wind turbine control

The motion control system consists of a controller whose purpose is to explicitly stabilize and reduce the floating system motions and keep the structural responses at or below the levels assumed in design. An important input to the control algorithm is an accurate Motion Reference Unit, measuring Heave/Surge/Sway and Roll/Pitch/Yaw in real sea conditions. The …

Floating Wind Base Motion Monitoring

For these applications, Norwegian Subsea’ accurate new generation Accelerometers, Motion Reference Units and inclinometers are essential. For Tension Leg Platforms, the integrity of the TLP tendons is very important. A failure of a TLP tendon can be detected by the accelerometers and subsequently the wind turbine can be shut down to avoid further damage.

Wind Lidar Buoys

The small size of the NORSUB MRU makes it ideal for buoy applications. The MRU can be delivered with a high-end magnetometer to provide accurate heading as well. This is useful for calculation of directional wave spectra etc. The NORSUB MRUs come with onboard real-time FFT analysis that is used to output significant motion amplitudes …

Gangway

As for AHC, it is very important with good measurements of heave motions in real sea conditions. But surge and sway motions must also be measured reliably. The Marine MRU has a special mode for gangway and other DP applications where the wave frequency motion of surge and sway must be measured accurately. This mode …
