The Golden Pass Pipeline Project is a large-scale natural gas transmission system supporting the Golden Pass LNG Terminal. Gulf provided FEED+EP and construction support services for the project, which includes a 68.6-mile, 42” diameter, ASME Class 600 mainline pipeline from the Port Arthur/Vidor, Texas area to near Starks, Louisiana, plus a 1.1-mile, 16” Class 600 lateral to the Florida Gas interconnect. The existing GPPL connects the Golden Pass LNG Terminal located in Sabine Pass, Texas, to nine (9) interstate & intrastate pipelines through dedicated interconnects and one storage interconnect. The project consisted of reversing the 42″ gas pipeline, by adding three (3) compressor stations, four (4) Interconnect sites, one mile Sabine Spur pipeline, and modifying two (2) interconnect piping facilities while maintaining the original pipeline functionality of 2,500 MMSCFD certificated ratable flow. In addition to that, the mentioned Sabine Spur will add an additional flow of 390 MMSCFD to the LNG terminal.
The three compressor stations totaled 150,000 horsepower: one 7000 hp electric-driven unit at Sabine Pass and two gas turbine-driven stations: One at Vidor with 2 units rated at 11,127 hp each; and the other at Starks, LA operating within a range of 80,000–118,000 hp. All 3 Stations together provide the pressure and flow capacity required to reliably support LNG export operations.
