This NACE standard recommended practice provides guidance in controlling and monitoring for corrosion, bacteria, and water quality to corrosion engineers, field corrosion, production, technical, and operating personnel, and others involved in corrosion control of seawater injection systems. This standard includes descriptions of equipment and practices for controlling and monitoring corrosion in seawater injection systems. This standard is adapted from a report produced by the former Corrosion Engineering Association (CEA). CEA operated in the United Kingdom under the auspices of NACE and the Institute of Corrosion (ICorr). This standard was developed by Task Group T-1D-47, a component of Unit Committee T-1D on Corrosion Monitoring and Control of Corrosion Environments in Petroleum Production Operations, and is issued by NACEInternational under the auspices of Group Committee T-1 on Corrosion Control in Petroleum Production. 

1.1 This standard covers aspects of corrosion control and monitoring in seawater injection systems.

1.2 Most seawater injection systems rely on coatings, linings, plastics, composite materials, and corrosion-resistant alloys (CRAs) to overcome potential corrosion problems prior to deoxygenation. Thus, these recommendations concentrate on controlling and monitoring corrosion in facilities downstream from deoxygenation.

1.3 This standard presents recommendations for controlling and monitoring corrosion in seawater injection systems. However, many of these recommendations may be applied to other types of water injection systems, such as:

(a) Systems for reinjection of produced water,

(b) Aquifer-sourced water injection systems, and

(c) River or surface water injection systems.
