Corrosion of Mild Steel Plates on Various Depths in a Marine Harbor Environment

Wall, Henrik LU and Wadsö, Lars LU (2013) In Marine Structures 33(October). p.21-32
Abstract
This article describes the exposure of mild steel plates for one year in a marine harbor environment on the Swedish west coast. Single steel plates where mounted on ropes and exposed to both the splash zone and the submerged zone in three different exposure sites in the harbor. The maximum depth of submersion was approximately 7 m below the mean water level. Salinity, dissolved oxygen content, pH and temperature were measured monthly from the mean water level down to the sea bottom at the exposure sites. One of the exposure sites was placed in a river outflow which is a part of the harbor and the two other sites were located inside the docks with access to the open sea. No significant differences between the corrosion loss in the river... (More)
This article describes the exposure of mild steel plates for one year in a marine harbor environment on the Swedish west coast. Single steel plates where mounted on ropes and exposed to both the splash zone and the submerged zone in three different exposure sites in the harbor. The maximum depth of submersion was approximately 7 m below the mean water level. Salinity, dissolved oxygen content, pH and temperature were measured monthly from the mean water level down to the sea bottom at the exposure sites. One of the exposure sites was placed in a river outflow which is a part of the harbor and the two other sites were located inside the docks with access to the open sea. No significant differences between the corrosion loss in the river outflow and inside the docks were found. The maximum corrosion loss for the exposed steel plates was almost three times as high as the mean corrosion losses for the 40-50 year old sheet pile walls in the harbor inspected in an earlier study. This agrees with earlier studies that have found that the corrosion loss is greater in the first few years of exposure. (Less)
