THE FIRST CORE-LOC BREAKWATER

Anton H. Holtzhausen

Abstract


The first project in which Core-Locs were used as the main breakwater armour unit, is a small craft harbour on the south east coast of South Africa named Port St Francis. The Core-Loc was selected based on economic advantages over other units. Stability of 15 t units was confirmed in a full three-dimensional model study. Construction of the harbour commenced in early 1996 and was successfully completed towards the end of 1997. Practical construction issues are discussed in detail. Core-Loc performance under construction stage storms was excellent and virtually no damage has taken place under design storm conditions subsequent to the completion of the structure.
