Wind, wave & current extremes for South Korean Ship Yard

For a large Ship yard in South Korea Aktis Hydraulics derived the extreme metocean conditions for various return periods including for:

• Typhoon and monsoon wind conditions;
• Extreme flow conditions – water level and currents;
• Extreme wind conditions.

For the Typhoon extremes Aktis applied the WRF model to account for land effects to account for mountains and hills surrounding the area of interest and to include land-use like forest and buildings. The model has been calibrated against many in-situe wind measurements.

The resulting winds were then used to force TUFlow flow modelling and details SWAN hindcast.

The flow and wave modelling have been calibrated against multiple  tide gages, flow and wave measurement locations. The storm surge and skew surge dynamics are of particular importance as they affect the wave propagation around the main land features until reaching the relatively sheltered locations of interest.

The image below shows the historic typhoon tracks generating high waves at the location of interest.
