Example Projects include:


SatFads, Saturation Fly Away System

US Navy’s Saturation Fly-Away Dive System (SATFADS)

SATFADS is a portable 1000ft saturation diving system for use on suitable vessels of opportunity. It consists of deck decompression chambers (6-person living chamber and transfer chamber), 3-person diving bell, hyperbaric life support equipment, system control center, and a man-rated handling system.




SRDRS Submarine Rescue System

Submarine Rescue Diving and Recompression System (SRDRS)

Since 2006 the US Navy has contracted Phoenix to maintain and operate the Submarine Rescue Diving and Recompression System (SRDRS). Phoenix engineers support maintenance and operations with analysis and design modifications to enable deployment of the rescue systems.

Since the SRDRS is a manned emergency rescue Navy asset, the system must meet stringent maintenance and certification requirements. Phoenix provides the engineering to meet those requirements. These efforts include Atmospheric Diving System (ADS) maintenance planning, mobilization analyses, vessel-of-opportunity surveys, deck loading calculations, and deck layout modeling.

Presure Tolerant Electronics

Presure Tolerant Electronics

Over the years Phoenix has studied the effects of pressure on hundreds of electronic components and built a database which is drawn upon for new pressure tolerant projects. The pressure testing profile used screens for infant mortalities, prior to long term testing.

Phoenix has conducted many successful deep water missions with PTE vehicles like xBot’s exploring inside the Titanic and documenting the bridge of the oil rig Deepwater Horizon.




Pressure Tolerant Lithium ion Batteries Pressure Tolerant Lithium ion Batteries

By using very high energy density, large format cells Phoenix batteries give kiloWatts power for days. Modules from 0.5 to 2 kWh can be stacked in series and parallel to make batteries up to 275 VDC and 100s of Watt hours.



USS Monitor Turret Recovery Spider

USS Monitor Turret Recovery Spider

The USS Monitor Turret Recovery Spider is a 25-ton, eight-legged claw designed for lifting the turret from the seafloor in 240 feet of water, where it had rested for 140 years. The eight claws are individually hydraulically operated and designed to grasp around and under the turret.




Harris Buoy

Harris Buoy

Phoenix initially reviewed and recommended changes to subsea equipment designs and deployment plans to increase system reliability and the installation weather window for a data buoy system off Sardinia, Italy for Harris. By the end of the project, Phoenix‘s efforts included hardware redesign, recovery of the failed system, replacement of this system with a temporary one, implementation of design changes, system testing, development of detailed installation plans & procedures, logistics support, and installation of a new system off Cyprus.


Ping Locator System TPL-40

Pinger Locator Systems

These systems are passive acoustic devices that detect and determine the heading to underwater pingers, most commonly found on aircraft, with frequencies ranging from 3.5 kHz to 50 kHz. Phoenix has developed both towed pinger locators and systems for underwater vehicles.





ORION is a dual frequency (57/240 kHz) two body towed side-scan sonar system designed, manufactured, assembled, and tested by Phoenix. It provides the US Navy with a deep-water search capability to a maximum depth of 20,000 feet of seawater.



Okeanos Explorer Telepresence System

NOAA Telepresence

This teleprescence system is a real-time shipboard ROV data acquisition, editing, and transmission system designed and built for the NOAA Office of Ocean Exploration & Research. It provides shore-side scientists real-time access to at-sea operations.



Katrina/Rita Database

Katrina/Rita Database

Phoenix developed a custom database for tracking tasking, salvage plans, vessel owners, salvage results, and associated cost data after Hurricanes Katrina and Rita devastated the Gulf Coast.




RIOH, Rigid Inflable Overhead Habitat


The Rigid Inflatable Overhead Habitat (RIOH) is a flexible, electromagnetically attached, fabric cofferdam designed, manufactured, assembled, and tested by Phoenix. The electromagnetic sealing ring, in conjunction with a marine fabric for the pressurized habitat walls, creates a lightweight, easily deployed habitat for use in underwater ship husbandry.




3-DAT, Damage Assesment Tool


The Underwater 3-D Damage Assessment Tool (3DAT) is a diver operated underwater assessment tool that creates a rapid, accurate and detailed CAD model of collision or accident damage to US Navy vessels in real time. The 3DAT is a portable, diver operated, articulated arm with either a laser scanner or contact probe providing the capabilities of an underwater CMM.
