Abstract

Port structures in many ports need large-scale rehabilitation measures due to neglected periodic maintenance. Therefore, a knowledge of the causes of degradation and damage, the methods of monitoring, maintenance and repair necessary for the life cycle management is essential. Since the area between MLWL and a point just below LWL is the location where the greater corrosion rate usually occurs, the WG31 proposed that the zone between MLWL and a point approximately 0.5 meters below LWL was LWL zone. The general of the degradation, inspection, maintenance and repair of materials in a marine environment, and the proposed LWL zone are presented in reference to the revision of PIANC PTC-II WG17 report by WG31.
