Our pipeline and facility engineering team met with the client to determine the most effective method of approaching this project. As a result of the accelerated project schedule, we provided review of as-built drawings and material test records simultaneously with a field visit and site survey to document existing conditions of each 14”x20” pig trap and auxiliary piping. Initially, we provided demolition and modification plans, which included site photos along with design drawings to modify the existing launcher/receiver barrels for repurposing as bidirectional barrels.

Ultimately, because of on the limited amount of material documentation for the existing barrels, the client decided that constructing new bidirectional barrels was more cost effective than modifying the existing barrels. As a result, we provided new barrel designs, revised barrel foundation plans, site piping modification plans, and associated bill of materials (BOM). Design documentation included assembly pressure and stress calculations, hydrostatic test plans, contractor scope of work, pipeline tie-in list and valve list, and both bidding and construction drawing sets.

With the deliverables in-hand the client can confidently construct and implement the bidirectional designs and react quickly and efficiently to changing market and supply conditions by changing the flow direction of their pipeline. "
