This standard specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, fabrication, installation, commissioning, operation, inspection and maintenance of cathodic protection (CP) systems for offshore pipelines for the petroleum, petrochemical and natural gas industries as defined in ISO 13623. It is applicable to carbon steel, stainless steel and flexible pipelines in offshore service, and to retrofits, modifications and repairs made to existing pipeline systems. Key words: Cathodic protection, impressed current, offshore pipeline, CP system design, galvanic anode, galvanic anode manufacturing, galvanic anode quality control, pipeline design for CP This nationally adopted ISO standard is not available for complimentary download by members.

Electrical isolation/continuity issues and coating issues to consider when designing and operating offshore pipeline cathodic protection (CP) systems. For owners, engineers, contractors, and operators.
Literature on cathodic protection (CP) in the ocean at depths greater than 300 m (1,000 ft). Reports extensively on deep water field test results and operating experiences.
A new design approach allows more precise design of cathodic protection systems, particularly in areas such as deep water or new geographic areas.
HISTORICAL DOCUMENT. Determining the potential and current capacity characteristics under laboratory conditions for aluminum and zinc alloy anodes used for cathodic protection.
HISTORICAL DOCUMENT. Materials, practices, and methods of corrosion control for fixed offshore structures associated with petroleum production. Three major areas: the submerged zone, the splash zone, and the atmospheric zone.
Application of CP to control external corrosion of carbon steel on-grade storage tank bottoms that are in contact with an electrolyte. Both galvanic anode CP systems and impressed current CP systems.
Defines minimum physical quality and inspection standards for cast sacrificial anodes for offshore applications.
Sets minimum physical quality and inspection standards for cast sacrificial anodes for offshore pipeline applications. Applicable to half-shell or segmented bracelet-type anodes, only.
