1974 - 1975

Design of coastal structures, harbour facilities and shipyards
1975 - 1976 Earthmoving, harbour and railroad construction ( Al Khobar, Saudi Arabia )
1976 - 1982 Design of the Storm Surge Barrier Oosterschelde. The Barrier is the last part of the Delta Plan protecting Holland against storm surges on the North Sea
  • Probabilistic approach of hydraulic loading
  • Risk analysis of the total system of the Barrier and probabilistic design calculations
  • Hydraulic model tests on elements of the Barrier consisting of large rocks (sill, bottomprotection)
  • Research on heavy floating equipment designed to assemble the heavy prefabricated concrete elements of the Barrier in full sea
  • Prediction of current velocities during the construction of the Barrier with mathematical tidal models
  • Research on and design of the breakwaters connecting the Barrier with the mainland
1980Design and risk analysis of an oil exploration island in the Beaufort Sea, Dome Petroleum, Calgary. The main structure of the island was formed by an wave breaking rectangular caisson wall.
1981Expert witness in the Whitstable Sea wall Enquiry, Canterbury City Council. The Sea Wall consisted of a wave breaking and sea retaining wall with a pebble beach in front
