Gas
Milhouse Engineering and Construction was tasked to develop a design package to reconfirm the Maximum Allowable Operating Pressure (MAOP) of a pipeline system for North Shore Gas, ensuring compliance with federal guidelines. The team meticulously researched the pipeline’s history, examining test records and survey data to inform their design approach. They designed test headers, determined optimal locations, and created traffic control drawings, compiling all components into a comprehensive engineering package for client submission.
Using AutoCAD, Milhouse developed a detailed hydrotest profile that established high and low point elevations, precise stationing, and ideal deadweight locations. They initiated permitting investigations, identifying the necessary regulatory and environmental agencies requiring notification, and determined the relevant federal codes and standards for the pipeline segment. The team calculated field test pressure requirements, presenting them in an accessible spreadsheet within the test plan report.
Milhouse also performed detailed calculations to ascertain the media fill volume, accounting for water compressibility, pressure and temperature variations, test header volume, and fitting size adjustments. Additionally, they developed a thorough procedure for the hydrotesting process, covering every aspect from line filling to pressurization, uprating, dewatering, and disposal. Upon completion of the test, Milhouse provided a comprehensive summary report for the client.
