Computer drafting system speeds pipeline design

This slice of right-of-way mapping from Williams Cos.' Transco unit's MarketLink system illustrates the computer-automated system for pipeline mapping, engineering design, and detailed drafting used by Paragon Engineering Services Inc., Houston, for the project.

The drawings were for 100 miles of 36 and 42-in. expansion loops in eastern Pennsylvania and northern New Jersey. Paragon used the automated system to deliver some 1,700 drawings at 25 man-hr/drawing. Transco states more traditional methods would have required 30-50 man-hr/drawing. With targeted start-up of November 2000, MarketLink will added approximately 700 MMcfd to Transco's deliverability to US Northeast markets.
