Manor Gate Station Upgrade
Baltimore Gas & Electric (BGE), the company that operates the entire Baltimore area gas distribution system and serves more than 650,000 customers, contracted EN Engineering to upgrade their existing Manor Gate legacy station. This station takes the transmission gas from TransCanada at 720 PSIG and lowers the pressure to 269 PSIG to feed BGE’s Beaver Dam and Notch Clift transmission lines.
The original BGE drawing showed 16” steel, but the pipe was 24”, so the spherical tee that was ordered for 16” did not work. A custom-made tee was ordered, which resulted in a 14-week delay. In addition, commissioning was delayed due to the frigid ambient temperature and weather forecast.
The Manor Gate Station upgrade project included two meter runs, four regulator runs, a separator/filter, heater, odorization, controls, and fire suppression, in addition to considerable construction of buildings and concrete to house this equipment. EN Engineering took the design work from conception through completion and also provided the environmental and construction materials testing, resulting in time and cost efficiencies. The team developed accurate and detailed as-built drawings, which required minimal field changes. The construction management team was on site and eliminated time lapses for design questions during construction. Throughout the project, they focused on jobsite safety, contractor oversight, adherence to BGE standards, and cathodic protection. In addition, they interfaced with the compliance team, Certified Weld Inspector, and NACE coating inspection. Weekly meetings with the client’s senior management team assured the project was on track, and the EN Engineering team’s expertise was welcome and respected.
