Undersea Operations

From our Largo office, Phoenix executes worldwide unmanned underwater operations to depths of 6,000 meters (20,000 feet of seawater). These operations involve subsea intervention systems, including our Autonomous Underwater Vehicle (AUV), Remotely Operated Vehicles (ROVs), deepwater sonar systems and other robotic systems, and subsea tooling in support of our deep ocean search and recovery efforts, geophysical surveys, and other subsea operational related services.

In addition to operating and maintaining our fleet of ROVs and subsea survey equipment, we operate and maintain several U.S. Navy-owned ROVs and underwater search equipment through a contract with the Naval Sea Systems Command. All these systems are housed at our Largo facility and deploy globally for deep ocean search and recovery operations.

Engineering

Our Largo office also serves as the primary home of our subsea-focused engineering department. Phoenix engineers specialize in designing and building underwater systems to assist in accomplishing projects in the marine environment. Phoenix’s ISO 9001:2015 certified Quality Management System (QMS) emphasizes assurance of engineering quality through controlled, disciplined, and well-defined work processes. Phoenix’s engineering capabilities encompass designing, building, testing, and integrating manned diving systems, tools, underwater sensors, structures, energy sources, and underwater vehicles.

Test Tank

The tank at our Largo, MD office is a 21,000-gallon, self-contained test tank located just outside or our warehouse. The tank measures 21’ L X 12’ W X 12’ deep and is surrounded on 2 sides by an aluminum catwalk with a staircase and egress ladder.  The tank features two observation windows to allow for viewing of undersea systems during testing.  A staging platform beside the tank offers an ideal location for pre-dive tests, maintenance, and troubleshooting.
