WASHINGTON – NAVSEA’s Recovery and Dive Supervisor (SUPSALV / 00C) demonstrated two new and innovative technologies at the Washington Navy Yard, December 8-9.

The systems, the Diver Augmented Vision Display (DAVD) and the Multiple Occupant Flexible Recompression Chamber (MOFRC), will improve safety and expand the capabilities of the Navy diver.

DAVD

The DAVD system improves situational awareness and efficiency of divers, especially in conditions of limited visibility.

DAVD incorporates transparent head-up display (HUD) technology easily adapted to current US Navy diving helmets. The system uses sonar and high-resolution optical display technology to deliver high-resolution data and images to the diver.

“With the DAVD system, our divers can work safely and efficiently underwater in low or no visibility conditions using high-resolution images provided by integrated sonar systems and technical data sources. Said SUPSALV Commanding Officer Captain Jay Young.

The DAVD system also includes two-way communication and the ability to transfer digital information to the HUD. The DAVD is developed and implemented through generational updates as technology advances and will allow:

  • Visualization of SONAR photographs and extracts in the helmet
  • Real-time display of critical data to include azimuth heading, current depth, maximum depth, remaining breathing gas, bottom time and elapsed time
  • High-resolution SONAR imaging of the surrounding area
  • Underwater navigation assisted by imagery and obstacle avoidance
  • 1st and 3rd person viewing capability using the SONAR 3D CODA Octopus
  • Three-dimensional augmentation and mixed reality displays in low visibility conditions

“DAVD is a game-changer. This allows us to travel safely and efficiently to and from a project and to maximize productivity during downtime, ”said Master Chief Master Diver Joshua Dumke. “This system coming from generation 1 to generation 2 is almost limitless with what we can do. It is not only a lifesaving and diving or ship-raising device, but has applications for other missions, including underwater explosive ordnance disposal, naval special operations, and countermeasures. fires on board ships.

The Panama City division of the Naval Surface Warfare Center (NSWC Panama City) initially developed the DAVD system in concert with naval and industry partners. Through a technology transition agreement from the Office of Naval Research (ONR), SUPSALV and OPNAV N97 and the Future Navy Capability indicator, the program will strive to develop Generation 2 and 3 capabilities at during fiscal years (FY) 2020-2023.

Multiple Occupant Flexible Recompression Chamber (MOFRC)

The MOFRC is a lightweight, highly mobile recompression system that can accommodate two divers and a dinghy.

“MOFRC gives us another tool for expeditionary forces in a lighter, easier to move recompression package in theater,” said Master Chief Master Diver John Hopkins. “The current budget allows us to acquire six low-rate production models, the first to be delivered next year.”

The MOFRC on display at the Navy Yard was a prototype model.

According to Hopkins, the chamber fits into six containers, with the heaviest container weighing 470 lbs. The total system weighs approximately 1,000 pounds less than the lightest recompression chamber currently in service. MOFRC can be transported by land, sea, or commercial and military aircraft on a single pallet of standard aircraft cargo, reducing the current load plan by 50%.

“It’s about having our own mobile recompression chamber. This is a system monitored by our own US Navy personnel. With MOFRC, we have greater flexibility to bring our own room to any theater we work in and use Navy certified equipment, personnel and treatment protocols. In short, it makes us autonomous even in the most remote areas where we work. Said Captain Thomas Murphy, Dive Supervisor (00C3B).

“The DAVD and MOFRC are prime examples of how we have used ONR funds to successfully transition breakthrough new technologies through development and acquisition,” said Michael Dean, director of the SUPSALV ocean engineering. “The costs associated with design and commissioning are not huge, but the impact on our ability to expand our capabilities is huge,” Dean concluded.
