Pipeline Monitoring

TransCanada PipeLines Limited has established a comprehensive program for in-line inspection of its extensive pipeline system. TransCanada has been developing inspection tools since 1968 and currently has three types of inspection tools capable of detecting corrosion on either the inside pipe surface or both the inside and outside pipe surfaces and/or mechanical damage (e.g., dents). Development of inspection tools continues and is mentioned briefly. A major development thrust is the creation of computer software for the interpretation of inspection data.
