Panhandle/Trunkline Backhaul Project


Energy Transfer partners wanted to create bi-directional flow capabilities along its interstate pipeline to efficiently increase the pipeline’s capacity and use. By creating bi-directional flow capabilities, Energy Transfer would be able to leverage its pipeline assets to respond to market pressures with minimal impact on the environment.


SKW provided the comprehensive mechanical, electrical, instrumentation and control, and programming design services at several key facilities.

The Panhandle Eastern/Trunkline Gas Reversal Project involved modifying four stations and three Gate Valve Sites to backhaul while retaining the capability to forward haul at the present capacity.

The Panhandle portion of the project involved four new suction separators, approximately 60 new large bore valves and 13 control valves, modification and actuation of approximately 75 existing valves, five new remote control buildings as well as associated new piping, and instrumentation, electrical and control system modifications.


The Panhandle/Trunkline pipeline backhaul capabilities increase the efficiency of Energy Transfer’s pipeline while allowing them to meet market demands.
