In desalination plants the corrosion failure of components due to environment-related factors constitutes a major part of the reported cases. This paper presents a few interesting case studies of the failed components of SWCC desalination plants of the Kingdom of Saudi Arabia. It has been recognized that the biofouling of offshore structures of desalination plants combined with sulfide contamination are responsible for (MIC) microbiologically-induced corrosion of components. A case study investigating the failure of monel bolts in the seawater intake pump has revealed severe MIC attack by sulfide-reducing bacteria. Failure of materials from (SCC) stress corrosions cracking in service due to combined and synergetic interaction of mechanical stresses and corrosion reaction is not an uncommon phenomenon in desalination plants. The second case study concerns th e investigation of a large-size, intermediate-bearing support block of a seawater intake pump. The results of the study confirmed that the failure is due to SCC resulting from the retained residual stresses during component manufacture. Another case study of the failure of the steam impingement plate of the desail chamber also indicate that the failure is due to SCC caused by the developement of thermal stresses during plate reinforcement. The methodolo gy adopted and the analysis of material/ corrosion products carried out are detailed. The issue that must be addressed in order to control corrosion and/o r failure are discussed.
