Page 160 - Pipeline Pigging Technology

The Zeepipe challenge

prior to commencement of the precommissioning and commissioning opera-
tions.

CONCLUDING REMARKS

By adopting the long-distance pigging concept, both the precommissioning
and commissioning operations have been significantly simplified. The need
for a midline platform on the Sleipner to Zeebrugge pipeline has been
eliminated, and more cost-effective alternatives are introduced for the future
compressor platform tie-in. This has further reduced the maintenance re-
quirement, and also eliminated intermediate pig handling during the opera-
tional phase.
