"PUSH-RACK" METHOD SPEEDS MARSHLAND PIPELAY

Acadian Gas Pipeline System earlier this year installed 13.5 miles of 20-in. concrete-coated pipe through marshes and bays of the south Louisiana coast (U.S. Gulf of Mexico) with minimal effect on the environment. A "push-rack" or production line was set up at the marsh boundary and five 12,000-ft sections of pipe were fabricated, floated into the marsh, and tied into each preceding section. The only traffic through the marsh was the marsh-buggy backhoes which were used to excavate and then backfill the pipeline trench. The push-rack technique enabled the contractor to complete more than 6,000 ft of pipe in one day. The push rack consisted of seven covered work stations 64 ft apart (the average pipe-joint length) which allowed work to continue during rain and windy conditions. Further details of the construction are provided in this article.
