Abstract
The wheat ship unloader in the harbour of Port Louis, in Mauritius, is facing corrosion problems. The atmospheric corrosion rate in Port Louis was found to fall in the category C4 according to ISO 9223. The main corrosion issue of the ship unloader relates to the high maintenance cost resulting from painting problems. Hence, this study was performed to determine the parts of the ship unloader most prone to corrosion through a corrosion risk assessment. The steps involved in the corrosion risk assessment include undertaking a criticality appraisal and determining the associated risk. Hence, the criteria for the Severity, Occurrence and Criticality of corrosion were defined. The risk rating for all the operating units, equipment and systems was determined. The components and subcomponents of the wheat ship unloader were studied thoroughly to categorise the corroded parts in order of priority. Solutions were proposed to decrease the cost of maintenance and the corrosion cost of the ship unloader as well as other similar structures.
