Petersen Engineering has recently been awarded engineering contracts for the design of gas gathering systems for three separate clients. Two projects are located in Western Pennsylvania and the third one is located in Southwestern Indiana.

One of the projects in Pennslyvania involves the design of the gathering sytem for a new grass-roots storage field with a maximum pressure of 3,500 psig. The main header will be 20" and the lines to the wells will be 8". Each well will have a meter skid that will be connected to a SCADA system. The design work will also include a 16-mile 24" delivery line.

The other gathering project was for a 12" high pressure main header that was replacing a low pressure plastic line. The design work included valve settings and launchers and receivers. PEI is providing field engineering and construction inspection to develop welding procedures per API 1104.
