Metocean conditions for the design of a floating power plant

Nouméa - New Caledonia

 

Client : Nouvelle Calédonie Energie

Date of completion : 2021



In the purpose of the design of the new floating power plant of Noumea deemed to be installed in the Bay, Globocean has performed a metocean desktop study in order to assess the non-cyclonic and cyclonic extreme winds , waves, currents and sea levels expected in the study area.


The following steps were followed for the realization of this study :

  • Implementation of a high resolution wind model inside the lagoon of Noumea (CFD software MeteoDyn)

  • Set-up of a parametric cylonic wind model (Holland empirical formulation)

  • Modelling of the offshore swell (software WaveWatchIII)

  • Implementation and execution of a wave propagation model within the lagoon taking into account the wave breaking effect on the coral belt

  • Implementation and execution of a 3D hydrodynamic model in the lagoon of Noumea

  • Assessment of the non-cyclonic and cyclonic extreme conditions at the pre-defined study points (EVA sofware, POT methodology)
