Piping Design to New Sphere
TITLE: Piping Design to New Sphere
Fee: $1.3 Million
Project Schedule: One year
A Butane sphere in a refinery tank farm failed inspection and had to be replaced. A sphere fabricator was contracted to provide the new sphere and its foundation, and PSE was contracted to provide the remaining engineering and design. The project development and engineering lasted over a year. PSE modified the P&ID’s to include the new piping, instruments, and valves to meet the current standards and requirements. PSE participated in Hazop reviews, Alarm Rationalization reviews, and numerous model reviews with the client’s operations, maintenance, process, controls, and management groups.
PSE provided Electrical, Instrumentation, Piping, Civil, and Structural engineering for the project. In addition, PSE worked with the plant fire water specialist and a third-party fire detection specialist to completely replace the existing sphere deluge system and the fire detection system.

Prior to the execution of the project, it was determined that the existing foundation would not meet current seismic codes, so a new foundation was engineered by the sphere fabricator. However, during the project the old foundation was found to be much larger than originally thought, interfering with the location for the new sphere. PSE worked to help develop a plan so that instead of removing the entire foundation, sections could be removed, allowing for new concrete piles to be installed. PSE also took on the responsibility for the Civil/structural engineering for all piping, supports, and foundations for the new sphere location.
