Liquified Petroleum Gas (LPG) Rail Unloading Facility

On behalf of a longstanding client in the oil & gas downstream market, MSB’s Instrumentation & Controls division delivered process design, detailed engineering, project engineering and project management services for a Liquified Petroleum Gas (LPG) rail-unloading facility construction project at a New Orleans area refinery. The project expands the refinery’s product distribution by converting industrial greenfield land into a fully-commissioned LPG rail terminal with four railcar loading/unloading towers designed for future vapor recovery capability. MSB’s team of engineers and designers assisted in developing the feasibility study, FEED analysis and cost estimates to evaluate the practicality of the construction. MSB also delivered detailed design, equipment and materials specification, FAT execution, installation/construction support, and start-up and commissioning services. To meet the ambitious construction timeline, MSB provided staged design package deliverables while construction was underway. MSB also tapped its team of seasoned engineers midway through the project to re-engineer the LPG railcar skid vendor’s automation controls from a multi-PLC simplex design to a single TMR Fault Tolerant alternative. Completed in 11 months, the project was successfully delivered on time and within budget.
