Abstract

Corrosion of steel members in the marine environment is a major problem. The deterioration of this kind of structures is costly and difficult to predict either when designing new structures or when estimating the remaining service life time for existing structures. The objective of this study was to determine the amount of steel remaining of corrosion piles on jetty structure in Surabaya Port, Indonesia. A jetty structure with a total length of about 1000 m was inspected. The age of the inspected pile structures ranged from 20 to 30 years. The assessments include visual survey, a site measurement survey, a review previous engineering document and analysis of pile condition data from corrosion measurement. The results indicate that the steel piles have thinning cross-section thickness between 1 to 3 mm due to corrosion attack. The average thinning cross-section of steel pile thickness occurring at the West Pier is more significant than at the East Pier and it corresponds to visual observations. The depletion of extreme thickness occurs both at the west pier and the East pier, which reaches more than 80% of the nominal thickness, which is likely due to a pitting corrosion.
