TENDO WAVE

Tendo module for calculating waveparameters.

This Tendo module can proces data coming from Datawell bouys. It transforms raw buoy displacement data into wave spectra. On these spectra a list of swell, seastate and full spectrum parameters (waveheight, zero up crossing frequency ..) are calculated.  Tendo is a powerfull platform for  real-time metocean applications that enables you to  store visualise and distribute these calculations.

FEATURES

Fast update rates

Gain time by getting faster parameter updates. 20 to 30 minutes faster response can be realized compared to bouy spectra parameters.

Sea Swell seperation

  • Seperates spectrum based on a separation frequency
  • Adjustable seperation frequency
  • Calculate parameters on the three parts ( Swell, Seastate, Full spectrum)

Calculate spectra

  • Calculate waveheight spectra from raw displacements
  • Adjustable displacements window length (10 – 40 minutes)
  • Calculate a new spectrum every 3 minutes

Timeseries analysis

  • Highest wave parameter can be is determined from the displacement data not the spectrum data
