For over 25 years, The Thoma-Sea family of companies have been constructing quality vessels for the commercial marine sector.
In early 1990, Thoma-Sea Boat Builders, Inc. started with a single shipyard located along the bank of the Intracoastal Waterway in Houma, La. There the Thomassie family began building projects for brown water towing and vessels for foreign fisheries. Thoma-Sea continued to expand, building offshore tugs, escort tugs, and small PSV's.
In January 2003, Thoma-Sea expanded by purchasing the then defunct Halter Shipyard in Lockport, Louisiana. This spelled the beginning of Thoma-Sea Shipbuilders, L.L.C. The acquisition of the Lockport facilities added the capacity to build larger, more complex vessels, and Thoma-Sea soon became a regional leader in PSV construction. Continued investments at the Lockport facility have continued to increase capabilities and productivity.
In 2005, Thoma-Sea expanded it's operations by breaking ground on a new construction facility in Houma, becoming the first tenant for the newly developed Port of Terrebonne.
In 2008, Thoma-Sea began repair and conversion operations in the Port of Terrebonne, and is currently expanding the repair/ conversion operations through the development of a new 60 acre site.
In 2010 Thoma-Sea merged the Lockport & Houma facilities under one entity, and Thoma-Sea Marine Constructors, L.L.C. was born. Utilizing the combined resources of multiple locations, Thoma-Sea is able to compete favorably, and offer exceptional value for our customers in the marine industry.
In 2012 Thoma-Sea completed the first phase of construction to the repair facility. The move to the entrance of the Port of Terrebonne poised the facility for future growth.
In 2013 Thoma-Sea completed the construction of our 4th dry dock adding capacity to lift and repair vessels in excess of 8000 tons.
In 2014 Thoma-Sea completed the installation of additional shore power and water stations.
In 2015 Thoma-Sea completed the installation of an additional 600' of bulkhead in the repair facility. We also started the construction of our 5th dry dock which will be in service summer of 2016.
