Project Scope

Graycor Industrial completed a major project at BP’s Whiting Refinery located along the southwestern shore of Lake Michigan in Indiana. Graycor served as general contractor on the Naphtha Integrity Project, a direct project with BP to construct its new Naphtha Splitting Unit located within the refinery. This facility replaces the existing plant and provides increased volume and technology enhancements. BP is investing several billion dollars in Northwest Indiana to modernize the Whiting Refinery to enable it to process heavier crudes.

Through detailed planning and coordination Graycor successfully completed the mechanical and electrical packages of the Naphtha Integrity Project with zero recordable safety incidents. The majority of the project involved piping system installation. For the gas distribution portion of the project, Graycor’s team performed:

Large and small bore pipe installation
Equipment setting
Structural steel erection
Electrical and instrumentation installation
Extensive activity coordination involvement with other contractors
The Whiting Refinery is the second largest refinery in the BP refining system and the sixth largest refinery in the U.S. BP is one of the world’s leading international oil and gas companies.
