Abstract

The head section of the north breakwater, at the entrance to the Port of Richards Bay, has suffered some damage since its construction in 1973. This paper briefly discusses the changes in the design conditions, the first unsuccessful repair in 1986/87, using 15t dolosse, the annual photographic monitoring results showing the rates of damage to the roundhead since then, and the model testing of various repair options, using available spare 20t and 30t dolosse. Finally the construction of the optimal repair, carried out in 1996, using a heavy duty mobile crane (with 48m boom reach) and DGPS positioning, is described. Construction was still in progress at the time of publishing this paper.
