TransCanada PipeLines Limited (TransCanada) has continued its leading effort in developing and implementing pipeline technologies. With a well structured and large-scale technology implementation program and collaboration of many partners over a period of three years, TransCanada has successfully implemented a number of technologies in a 38 km long NPS 42 pipeline construction project. The technology implementation program included installation of 7.3 km Grade 690 (X100) pipe supplied by two manufacturers, deployment of tandem welding system, field trial of a phased array automated ultrasonic testing (AUT) system, the application of high performance composite coating (HPCC) and Alternative Integrity Validation (AIV) process that led to first ever construction hydrostatic test waiver from National Energy Board. The paper provides an overview of the technology implementation program and the experience gained in applying a wide range of advanced pipeline technologies.
