Through the years, GIS has continued to grow on the founder’s business philosophy into a vigorous service-oriented company providing a full range of construction services.


Grand Isle Shipyard, Inc. was founded in 1948 by Clyde & Ouida Pregeant, initially as a response to the need for repair services of commercial fishing vessel. The business was first located in Grand Isle, LA.

In the early 1950’s, the Oil & Gas Industry entered the Gulf region and commercial fishermen began modifying their vessels to support this developing industry. The founders took advantage of this opportunity to expand the business to service both the fishing and oil industry, and began repairing wooden luggers that serviced the oil rigs. Also in the 1950’s and 60’s, Clyde & Ouida’s sons became involved in the business. Robert “Bobby” Pregeant was first to begin as a machinist apprentice in 1958. Clyde, Jr. followed shortly after in 1959 as a welder’s helper. Finally, Richard “Dickie” Pregeant joined in as a roustabout and equipment operator in 1975. All the boys quickly learned their areas of the business and advanced through different supervisory positions.

By the early 1980’s, with the second generation solidly in place as President, Treasurer, and Secretary, the company strategically transformed its image from that of a dual service provider to an oilfield service company. Grand Isle Shipyard came to be known in the industry as “GIS Oilfield Contractors”. The new generation of management refined the service offerings of fabrication and construction crews. As before, the next generation became involved in the family business around this time. This third generation of boys – Mark, Bryan, and Brad – all began as helpers and hands, working their way up the ranks as their fathers had done before them.

As the 1990’s rolled around, the third generation of the family began to be more actively involved in leadership of the company. At this same time, the company also refined its mission and vision – and, along with the rest of the industry, really began to focus on safety. GIS’s first corporate & state-approved safety management plans were implemented in 1994, and the first behavior-based safety program was kicked-off in 1997.

Through increased organization and safer work practices, the company was able to focus on growth and quickly added fabrication facilities, as well as other service lines and locations, over the next decade. At present, Mark Pregeant serves GIS as CEO, Bryan Pregeant & Brad Pregeant are operations Vice Presidents. As with lineage before, the next generation of Pregeant’s has begun involvement in GIS, working their way up just as their fathers and grandfathers have done before them. In addition to family, GIS has built a core management team of individuals who also have the first-hand oilfield experience it takes to motivate and lead others. The company continues to refine and grow through strategic practices and always Putting People First.
