Shell Chemical’s world-class petrochemicals facility in western Pennsylvania converts ethane gas supplied from local shale gas development. Ethane is sourced from multiple third-party local gas producers and converted in a 1.5 million metric ton cracker with three polyethylene trains to pellets that are shipped from the site to local customers and export markets. The facility includes an ethane cracker that produces 3.3 billion pounds of ethylene per year, that feeds three polyethylene units. Facility infrastructure and utilities, storage, and warehouses were also built to support the process units.
PMA performed a schedule risk analysis of the mid-implementation schedule that primarily consisted of construction work. Given the scale of the project, PMA developed a mega-model-a resource-loaded CPM schedule that replicates the entire project. PMA also interacted with the Shell project team to ensure all known schedule risks were addressed in the simulation of the mega-model.Overview
