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.
As CORROSION journal celebrates 75 years of corrosion mitigation and control research in 2019, we offer a selection of articles by decade. These articles remain the most viewed research articles of their respective decade, highlighting important topics, experimental methods and discussions surrounding the pertinent research of the day, and they continue to provide intelligence, perspective and insights for today’s corrosion research.
A top-of-line corrosion (TLC) model integrated into a CO2/H2S corrosion prediction model. The TLC model determines the top of the line corrosion rate of carbon steel based on water chemistry and film-wise condensation rate. The effect of various glycols, such as Monoethylene Glycol, Diethylene glycol and Triethylene Glycol, are included.
