Toulon (France)
Client : Bonna TP
Date of completion : 2022-2023
For an execution study, Globocean has assessed the hydrodynamic forces expected to apply on the exhaust pipeline of the water treatment plant of Cap-Sicié at Toulon once every fifty years on average, for the design of the ballasts in order to ensure its stability.
The following tasks were successively performed :
Modelling of the offshore sea states (software WaveWatchIII)
Assessment of the extreme waves expected once every fifty years, by direct extreme value analysis (uni-variate EVA software)
Propagation of the 50-yr extreme sea-states in the nearshore area (software SWAN)
Modelling of the orbital velocities and accelerations (numerical wave flume model IH2VOF)
Derivation of extreme drag, inertial, and lift hydrodynamic forces (Morisson formulation), and advice about the ballast weight to consider for the stability of the exhaust pipeline
