The Robinson Butane Cavern is one of the largest hard rock storage caverns in the world, with a capacity of 1.4 million barrels. The cavern enables the refinery to store excess butane produced throughout the summer, and provides a lower-risk alternative to transporting butane via pipeline and rail.
WSP provided engineering design, procurement and construction management for the cavern, located about 700 feet below the Marathon Petroleum Company’s refinery. Frank Jurica served as deputy project manager.
The project team collaborated with the client, local community, Illinois state leadership and regional WSP staff, and managed more than 90 subcontractors throughout construction. The project achieved an outstanding safety record, with zero recordable incidents, while improving mining productivity, enabling delivery of the project 11 months ahead of schedule and more than $4 million under budget.
