ROVs — Remotely Operated Vehicles

REMORA (II & III) Line of ROVs

Phoenix International’s Remora ROV systems perform work to water depths of 6,000 meters (20,000 feet), and were designed and built in-house to meet our unique requirements. Our ROV personnel were heavily involved in the design of the system, relying on their many years of experience to ensure that the final design met the hazardous requirements of operating in extreme water depths while maximizing the reliability of the system.

Currently, Phoenix owns and operates two Remora ROVs, called Remora II and Remora III. Both Remora ROV systems use an industry proven fiber optic cable, have state-of-the-art sensors and telemetry systems, and are equipped with dual manipulators. The compact design and small footprint allows these systems to be easily transported anywhere in the world by air or sea, and quickly mobilized aboard vessels of opportunity to provide cost effective support for a wide range of underwater tasks.

Remora II is a 25 horsepower (hp) vehicle that delivers an impressive amount of horsepower per cubic vehicle. Remora III, which has been upgraded to 40 hp, offers even more power. Both vehicle configurations offer small physical size coupled with axial lateral thruster geometry permitting precisely controlled maneuvers in the tightest of spaces minimizing the probability of entrapment or entanglement.

Both Remora II and Remora III utilize a fiber optic cable containing 3 power conductors and 3 single mode optical fibers. Two of the fibers are available for customer use for integrating additional customer or Phoenix supplied equipment to meet job-specific needs. The cable is stored on a winch integrated with a self-contained, compact, air-transportable handling system featuring an electro-active level wind, self-erecting ‘A’ frame with docking head, and electro-hydraulic power unit.

The Phoenix owned and operated Super Mohawk II™ is a 2,000 meter (6,500 ft) depth rated, observation class Remotely Operated Vehicle (ROV) that is ideally suited for offshore underwater tasks including inspections, surveys, and light to medium work.  The system is robust, durable and highly maneuverable, and can be supplied as free flying or with a Tether Management System (TMS).  It is designed for high payload, has plenty of open deck space and multiple skid mounted options for task specific job functions.  The SubCan control system provides advanced diagnostics, precise vehicle control and reduced reactive maintenance.


Phoenix International’s xBot® III is a specialized third-generation vehicle that builds off the experience gained with its predecessor xBot® micro-ROVs. Characterized by its small footprint, high maneuverability, and low cost, this inspection and video documentation ROV was specifically designed and built by Phoenix engineers to penetrate hard-to-access or dangerous areas, such as the interior spaces of sunken shipwrecks. Our xBot® II series was made famous by James Cameron, who tasked Phoenix to build four xBot®s for a documentary he produced for Discovery Channel called “The Last Mysteries of Titanic”.

Designed to operate from an underwater host platform (ROV, sled, or submersible), the battery-powered xBot® requires only a fiber optic link. The xBot®s eliminate the use of pressure vessels and penetrators (except for the camera) by using oil compensated, pressure tolerant components which allows for a reduction in the overall vehicle size, weight, and cost. In 2010, the xBot® III was successfully deployed to conduct a forensic inspection of the inside space of the control room of the Deepwater Horizon, the drilling rig involved in the massive BP oil spill in the Gulf of Mexico earlier that year.
