Our Ship Building & Refurbishing History

Providing shipbuilding and refurbishing services in the Houma, Louisiana area since 1947

Founded by Arlen B. Cenac, Jr.’s maternal grandfather, Horace “Jack” Guidry, Main Iron Works has been providing shipbuilding and refurbishing services in the Houma, Louisiana area since 1947.

Main Iron Works has quickly became a major shipbuilding enterprise, building its first steel boat on Bayou Terrebonne near present-day Terrebonne General Medical Center. Guidry brought a set of skills to the organization, which still set the standard for company operations to this day. Main Iron Works initially began operations on Main Street (which is how it earned its name) in downtown Houma, Louisiana and eventually settled into its current headquarters at the 50-mile marker of the Intracoastal Waterway in 1961. Since its conception, Main Iron Works has become one of the leaders in the tug construction industry, offering the building of push boats, tugboats, specialty boats and fishing vessels for marine transport companies nationwide.

Main Iron Works was acquired by Arlen B. Cenac, Jr. and the Cenac Group in July 2015.

The innovative shipbuilding company was acquired by Arlen B. Cenac, Jr. and the Cenac Group in July 2015. Following the acquisition, Cenac Marine Services has continued to operate Main Iron Works as an independent entity under the Cenac Group umbrella, growing its construction of world-class, innovative push boats. The acquisition has also enabled the shipbuilding leader to expand services to also include a full service machine shop. Facilities and operations have since been modernized in order to improve upon the foundation of quality set so many years ago by Cenac’s grandfather. While under Benny Cenac’s leadership, Main Iron Works has remained a leader in tug construction while also becoming a perfect complement to Cenac Towing’s core mission. The two companies’ combined make for a dynamic duo.
