We’re a growing company with a proud tradition of service.

What began in 1952 with one man’s vision and a tankerman’s license has grown to include 3,500 employees working at refineries, terminals, chemical plants, and warehouse operations across the U.S. and Canada.



Petroleum Service Corporation (PSC) was founded in 1952 by Derryl H. Haymon in Baton Rouge, Louisiana. The company was the first to provide Coast Guard–licensed personnel to load and unload tank barges on the Mississippi River and other inland waterways. These men were known as “tankermen,” and PSC was the country’s first “tankerman service.” PSC remains the oldest and largest tankerman service in the U.S.

In the 1960s, PSC began providing other product handling services to major oil refineries, chemical plants, and storage terminals. Growth and expansion in the refining and chemical industries in North America over the past decade created new opportunities for PSC to expand its geographical footprint beyond the Gulf Coast.

From May 2004 to June 2019, PSC operated as a subsidiary of SGS, the world’s largest inspection, verification, testing and certification company.

A new chapter in the PSC’s long, distinguished history began on June 21, 2019 when Aurora Capital Partners, a leading middle-market private equity firm, announced the acquisition of PSC from SGS.

The company continues to operate under its historic name, Petroleum Service Corporation. Our PSC leadership team is excited to partner with Aurora to accelerate PSC’s growth potential and fulfill our mission to provide best-in-class service to our customers and rewarding career opportunities for our employees.
