Established in 1948 in Grand Isle, LA, 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. 

Today, GIS services the oil and gas, power, renewables and critical infrastructure industries nationally and internationally. With nearly 3,000 employees, 21 strategically located facilities, and 20 service lines, GIS has the resources to span the complete life cycle of our customers' projects, and the capability to provide solutions in  all the markets we service. We align our services with operations from the development stage of major projects, through construction, commissioning, and ultimately decommissioning.
