Subject: Pipeline Pigging Compliance
I am interested in getting advice/suggestions on pipeline pigging
requirements. In our Nigeria operation, pipelines equipped with pig
traps are required to be pigged at least every 5 years.
1.      Is this interval normal? Not too frequent?
2.      What of pipelines that were pigged but, for some unplanned
reason, were not used for about 1 or 2 years? How do you address the
compliance issues of 5-yr pigging? Do you just pig after 5 because the
regs say so? Or do you wait until the pipeline has been used for 5

Remember - safety statistics are more than mere numbers. These are real
people we are talking about.
