• Tidewater: Tidewater is one of the world's largest operators of offshore support vessels (PSVs, AHTS), serving the same global offshore energy customer base as DOF. Direct competitor in OSV chartering and offshore marine services.
• Oceaneering International: Oceaneering is a leading provider of ROV operations, subsea intervention, tooling, and offshore personnel services. Competes head-to-head with DOF in subsea robotics and IMR, and is referenced as a peer in the underwater drones / ROV market.
