From 1969 ground anchorages were installed at Aberdeen Harbour to accommodate increases in quay wall depth brought on by accommodating a fully tidal harbour. For the majority of these anchorages, the corrosion protection measures employed would be judged inadequate by today's standards. The paper assesses the results of visual inspections and metallographic examinations, undertaken in 1991 and aimed at identifying the nature of corrosion on samples of strand that failed during testing.
Observations are compared with a similar programme of inspections, carried out on 35 year old anchorages on the River Thames in London, and undertaken in 2005. Observations confirmed that, the anchor head protection on both contracts was not fit for extended use and were all in various states of corrosive degradation. The paper also describes the rating system, developed to create objective consistency in the inspection process, and the procedure used to extend the service life of the existing anchorages.
