Grand Isle Shipyard

Established in 1948 in Grand Isle, Louisiana, GIS began as a modest company serving the commercial fishing industry. It quickly evolved, entering into the emerging Oil & Gas industry in the Gulf of Mexico. Just as its founders, Clyde and Ouida Pregeant responded to clients’ ever-changing needs, GIS has advanced and diversified to become one of the industry’s most capable and trusted energy partners. 

Today, with over 2,000 employees, 18 strategically located facilities, and 21 service lines, GIS has the resources to span the complete life cycle of our customers’ projects, and the capability to provide solutions in the upstream, midstream, and downstream markets. 

We align our services with operations from the development stage of major projects, through construction, commissioning, asset management and ultimately de-commissioning through our GIS, LLC parent company as well as our affiliated companies: GIS Engineering, LLC and Blanchard Industrial, LLC.
