As the navigation infrastructure in many nations reaches and exceeds design service life, maintenance requirements and associated costs have increased. Operation of this navigation infrastructure is often impacted by its deteriorating condition. Effective repair and preservation measures are required to extend the service life of these assets well into the future. The purpose of this report is to present a compilation of inspection and repair techniques, both existing and emerging, that many nations may find useful for the maintenance of navigation infrastructure.
rnrnA large percentage of navigation structures are reaching the end of their design lives. Funds to repair or replace existing infrastructure are typically scarce. As a result, cost-effective inspection and repair of these assets is vital to the commerce and welfare of the industries and populations that these systems support.
rnrnThe primary objective of this report is to present the results of the Working Group?s efforts to collect and compile information from a variety of nations, agencies and operators throughout the PIANC membership on the methods, tools, materials and equipment that are used in the inspection, repair and preservation of navigation structures.rn
