We Move It. We Build It. We Deliver It. Nobody Does It Better. Backed by 130 years of operating history and the expertise of 700 knowledgeable mariners, we specialize in reliably transporting bulk liquid chemicals and fertilizers, providing expert towing services, and designing custom barge transportation solutions. Southern Devall is supported by our two subsidiaries, Devall Fleeting, a fleeting and shifting service provider with several facilities along the Gulf Intracoastal Waterway and the Lower Mississippi River, and Devall Diesel Services, an industrial engine dealership & service center that sells, services, and rebuilds industrial engines and generator sets. This unique combination of offerings makes us one of the most efficient operators in the chemical and liquid fertilizer transportation markets.
