THOMA-SEA MARINE CONSTRUCTORS, L.L.C.

Thoma-Sea Marine Constructors, L.L.C. specializes in the construction, repair, and dry dock maintenance of U.S. Coast Guard and Department of Defense vessels, with deep expertise in shipyard operations, structural rehabilitation, and mission-critical vessel modernization. The company delivers precision shipbuilding and repair services under stringent federal maritime standards, including dry docking, hull integrity restoration, propulsion system overhauls, and hull-to-deck integration for patrol and response craft. Their technical proficiency spans naval architecture, marine welding, corrosion control, and compliance with U.S. Coast Guard and Navy maintenance protocols, ensuring operational readiness for high-demand maritime missions. A key differentiator is their consistent execution of time-sensitive, mission-essential repairs on cutters and auxiliary vessels, often under compressed timelines and in demanding coastal environments. The contractor maintains a strong, recurring relationship with the Department of Homeland Security, primarily supporting U.S. Coast Guard fleet sustainment through scheduled dry dock cycles and deferred maintenance on cutters such as the CGC Cobia, Alligator, and Kathleen Moore. They also provide critical repair services to the Department of Defense, including shipyard preparation and dredge vessel maintenance, demonstrating adaptability across military and civilian maritime platforms. Thoma-Sea Marine Constructors operates exclusively within NAICS 336611, focusing on shipbuilding and repairing—a niche requiring specialized infrastructure, certified marine welders, and certified quality assurance systems. Their market positioning is that of a regional shipyard contractor with proven capability in executing complex, government-mandated vessel sustainment programs for federal maritime agencies. Based in Houma, Louisiana, the company is a privately held limited liability entity with no federal certifications on record. Their geographic presence is anchored in the Gulf Coast, leveraging proximity to major Coast Guard and Navy maintenance hubs to support rapid response and logistical efficiency in regional maritime operations.
