Reinforced concrete seawater intake structures are a critical component to enable continuous operation of power stations desalination plants petrochemical plants and other heavy industries located near to the coast. The primary objective of these structures is to supply a reliable quantity of clean seawater which can be used as per plant or refinery requirements.For continuous operation seawater intake structures require protective screens to prevent debris and marine life entering and damaging the pumps. These screens are often manufactured from stainless steel 316L however within the Middle East this grade of stainless alone is considered insufficient to provide long term corrosion resistance. To overcome this problem Cathodic Protection systems are utilised to protect the submerged sections of these screens with the aim of extending the life of the stainless steel equipment.This paper will focus on the various design parameters required for CP of SS316L screens with particular attention on design and operational current density values and suitable protection criteria. The detrimental effects of overprotection will also be discussed.Suitable case studies will be used to highlight the various type of anode systems available methods of monitoring and how maintenance worries can be overcome by state of the art remote monitoring and control systems capable of controlling large scale CP systems from a single location using standard internet web browsers.

 

Key words: Cathodic Protection, Remote Monitoring, Anode System, Reference Electrodes, Protection Criteria. Stainless Steel, Current Density, Protection Potential, Overprotection.
