When it comes to your business, there’s no margin for error, our marine solutions are tried, tested, and sometimes unexpected.

Construction & Maintenance

Our experienced mechanical and industrial engineers design and build on shore and at sea. And our marine equipment, supplies, vessels, and logistics capabilities prepare us for the duration of the job.

We also know it’s not always about building up, or tearing down. Smart, routine maintenance of your marine systems sustains your momentum while deferring the need for big-ticket expenditures.

From port and dock maintenance to refinery and bulk terminal care, your productivity inspires our solutions.


Couvillion Group holds Louisiana state contractor licenses in heavy construction, building construction, highway, street, and bridge construction, as well as municipal and public works.

At Couvillion, we cut our teeth on tough situations. From Hurricane Katrina to the Deepwater Horizon oil spill and beyond, our work along the Gulf Coast has prepared us to support public and private clients during all phases of the disaster recovery cycle. From vessels and equipment used for demolition and disposal, to logistics management and specialized crews for reconstruction, we manage and execute the entire recovery process.

Vessel Salvage and Demolition


After recovering more than 500 vessels along Louisiana’s coast, we’ve learned some lessons and perfected our methods. But sometimes we’re still surprised — and challenged — by what we find.

Whether we are returning vessels to service or performing demolition, our primary concern remains the safety of our people, the environment, and the integrity of our clients’ assets.

Oil, Gas & Petrochemical


A deft combination of skill and equipment allows us to offer support to Gulf of Mexico oil fields from inland waterways and sounds to those up to 12 miles off shore.
