WATER SUPPLY AND PIPELINES

Parsons experience surveying, routing, engineering, designing, and constructing steel and concrete pipelines includes work on most continents and many thousands of miles of pipe laid over the most difficult terrain. Pipeline systems to transport water, petroleum products, gas/gas liquids, and solid slurries have been designed and constructed to feed cities, industrial complexes, military facilities, airports, and marine terminals with a controlled, enclosed, steady supply of the pipeline product.

Parsons has extensive analytical and design experience in all pipeline technical issues including pressure surge protection, two-phase flow liquid slug/holdup analysis, slug catcher sizing and stress design, leak detection technology, corrosion protection systems, pigging applications, and operational and safety control technology. Gas and liquid gathering and transmission pipeline systems are computer analyzed to ensure configurations that are optimized for initial and operating costs. Parsons uses proven pipeline computer analysis techniques to provide safe, reliable, and economically optimized system designs.
