Edison Chouest Offshore (ECO) operates in the maritime transportation sector, owning and operating a large and diverse fleet that supports offshore and subsea operations. The fleet numbers more than 200 vessels, ranging from 87 feet to over 360 feet in length. The company traces its origins to 1960, when it was founded as Edison Chouest Boat Rental in Galliano, Louisiana, and it is now based in Cut Off, Louisiana. A core element of its business model is the ability to design, build, own, and operate its vessels, enabling integrated, high-capacity marine transportation and support capabilities. This combination of asset ownership and engineering capability informs ECO's role in the maritime industry. ECO serves a global customer base with services that include subsea support, integrated bridge systems, and global communications to support offshore operations. The company has pursued developments in maritime technology to extend its capabilities, including a 2026 collaboration to design and produce autonomous surface vessels in U.S. shipyards with Anduril Industries and HD Hyundai.
