Conclusions Seawater injection systems experience corrosion problems partly because of spe cific shortcomings associated with activi ties such as sampling, analysis, chemical treatment, and performance monitoring. • Two common shortcomings that ad versely affect the aforementioned specific ones are inadequate com petency levels and poor data man agement. • In tandem with the integrity man agement measure concept, a corro sion management process through its more comprehensive approach can offer an improved methodology to address and resolve the existing integrity management issues associ ated with a typical seawater injec tion system. • Th e c orro sion mana gem ent ap proach considers both corrosion a n d n o n c o r r o si o n e n g i n e e r i n g based parameters and shortcom ings. Therefore, it could address is sues such as inadequate competency levels and poor data management that would not be considered by an approach based on corrosion engi neering factors alone. Recommendations • Implement the following corrosion management components as listed in Table 2: — The IRP — Performance monitoring — Effectiveness assessments • Where special disciplines or specific knowledge is required during an IRP, seek specialized help from compe tent individuals to address the is sues and produce solutions. • Use the categorizations in Table 2 to cover and address both specific and general shortcomings associated with a typical seawater injection sys tem. This generalized approach may be successfully adapted to other types of systems. References 1 A. Morshed, "The Evolution of the Corrosion Management Concept," MP 52, 8 (2013): p. 66. 2 A.
