We are pleased to announce that effective October 1, 2021, Grand Isle Shipyard, LLC has acquired Sun Industries, LLC. With an eye toward future growth, Grand Isle Shipyard, Inc. (GIS) and Sun Industries, LLC (Sun) are taking a momentous step in their collective evolution through the acquisition to enhance capabilities within the electrical and instrumentation services.


Both companies view this purchase as a strategic partnership. Berthelot along with the entire management team will stay on in the same capacity. The transition to GIS ownership will be seamless and operations will continue as usual.

Todd Berthelot, Sun CEO & President

“The combination of the GIS and Sun organizations immediately generates a unique competitive advantage allowing us to capitalize on the emerging energy economy. Sun’s impressive client base will also now have access to GIS’s vast capabilities and geographic coverage, providing us with immediate opportunities to grow these relationships with an expanded service offering.”


This new partnership brings significant assets, resources, networks, and opportunities to enhance, diversify and expand lines of work. Together the teams will continue prioritizing our values, traditions, and commitments to quality, safety, and people. 

Mark Pregeant II, GIS CEO and President

“The agreement is beneficial for both organizations due to our industry experience, stability, and our reputable client base. The overall goal is for continued growth for both the organization and our people. Having similar family-based cultures, along with safety and quality, will ensure our employees remain the most valued in the industry.”

By combining these entities, this will allow us to:

  • Strengthen self-performance capabilities.
  • Give access to broader base of resources to pursue opportunities.
  • Support diversification outside of the traditional Oil & Gas model and support the transition towards New Energy.
  • Keep the organization at the leading edge of the construction industry for the entire asset life cycle, from design to construction to maintenance to decommissioning. 
  • Offer job security and career growth for our employees through expanded service offerings.


The addition of the Sun team will increase the corporate headcount by 85 employees with offices located in Brusly, LA, as well as with support from all other 12 GIS facilities in Louisiana and Texas.

Mark Pregeant II, GIS CEO and President

“We are excited for Sun to join our team as we continue to build on the GIS legacy of Putting People First while being able to provide exemplary services to our current and future clients.”


Founded in 1979, Sun began as a small electrical repair and maintenance company.  Sun has grown into a multi-regional, full-service operations, maintenance, and construction company. Sun has a strong safety record, maintains a staff of experienced and dedicated employees, and embrace innovation in approaches to their service delivery which are priorities that have allowed Sun to become recognized as one of the most diverse electrical solutions providers in the region.
