Challenges associated with coordinating the modelling, design, and installation of an alternating current interference and mitigation systems. The project consisted of a 65 kilometer long double circuit 500 kilovolt (kV) overhead transmission in a heavily congested right-of-way corridor with more than 80 pipelines.
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.
Describes a method to show equivalence of other methods for measuring the level of contamination of salts on surfaces to the Bresle patch method defined by ISO 8502-9. A definition of equivalence is provided, along with information on the allowable range of variance, test methods, preparation of steel panels, data analysis, reporting, validation of test methods, and rationale for testing. This standard is an aid to those who must comply with the International Maritime Organization (IMO)’s Performance Standard for Protective Coatings (PSPC).PRINTED HARD COPIES REQUIRE A MINIMUM OF 7-10 DAYS FOR PROCESSING BEFORE SHIPPING.
