Today, multi-purpose, built-for-purpose, all-in-one, pipeline integrity automation, wireless, data communication radios are available that monitor and report all cathodic protection rectifier operations, automate rectifier interruption, monitor rectifier operational status, monitor and report pipe-to-soil potential, pipeline pressure and pipeline pigging operations.
Pressure cycling and ultimate failure pressure testing was conducted on various pipe samples to verify the design formulas meet the specifications and are correct for use in design of field repairs. Results show that use of strain-based design methodologies for composite repair systems is suitable and effective.
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.
