ABSTRACT ABSTRACT The proposed system is designed to be divided into five major sectors viz., utilities, transportation, infrastructure, government, and production and manufacture. Each of these major sectors are further divided into sub-sectors and then blown down to industry and specific identity. The proposed system will enable end users to provide corrosion and cost related data through web-based online system. The input information from end users will be authenticated by a corrosion auditor before finally entering it into the database tables. The system is also capable of generating reports related to corrosion cost, which the nation is paying, with further details of corrosion costs borne by each sector and sub-sector and sub-sectors. These reports will be helpful in making a decision to identify the sector and sub-sectors which are more prone to corrosion and thereby consume more money to combat corrosion. Finally, the sectors and sub-sectors which are identified through the proposed system can be put under thrust research areas to combat corrosion problem and hence reduce the corrosion cost burden in future. INTRODUCTION Corrosion is a threat to industries and the nation and it is hidden everywhere which makes it more dangerous. The Kingdom of Saudi Arabia has vast stretches of land but most of its economical and industrial development has taken place in the coastal zones. The Saudi Industrial development is mainly based on chemical, oil, and gas related activities. Tems and Al-Zahranipresented a comprehensive review related to cost of corrosion and the methodology adopted for their study. The authors reported that for Saudi Aramco’s five domestic refineries, 36 % of maintenance budget was due to corrosion and 25% for gas sweetening plants. For gas fractionation plants, 17 % of the maintenance budget was due to corrosion while 28% for onshore production operations.
