Corrosion of steel structures in the marine environment is a major problem. The deterioration of this kind of structures is costly and difficult to predict both when designing new structures and when estimating the remaining service life time for existing structures.

The aim of this investigation was to find indicative values for the corrosion rate of steel sheet pile wall on the Swedish west coast. Such corrosion rates (mm/year) can be used both when designing new structures by oversizing the steel thickness and when estimating the bearing capacity of existing sheet pile structures.

Earlier investigations on the corrosion rates along the Swedish east coast - with salinity from about 0.2% to 0.8% - are still used today as guidelines for the corrosion rate of all steel structures in the Swedish maritime environment even though the salinity on the west coast can be as high as 3.0%.
