OceanWorks Atmospheric Diving Suit (ADS)

The best current example of non-hyperbaric underwater intervention.

The secret is in the pressure balanced joints.

Note claws and limited visibility.

unmanned vehicles
Unmanned Vehicles
  • ROVs
  • AUVs
  • Hybrid Vehicles
slide12
ROVs
  • Free-Swimming
  • Bottom Crawling
  • Structurally Reliant
free swimming rovs
Free Swimming ROVs
  • All are tethered
  • Tether provides, power and data
  • Equipped with video/TV Cameras
  • Highly maneuverable
