  1. Review of Underwater Vehicles Module 1, Section 1

  2. Types of Underwater Vehicles Insert Fig. 1.3 from text book

  3. Types of Underwater Vehicles • Manned Vehicles • Unmanned Vehicles • Non-Vehicles

  4. Submarines Atmospheric Diving Suit Manned Vehicles

  5. Submarines • Military • Research • Tourist

  6. Military Submarines Classified by Propulsion System: • Nuclear • Diesel-Electric Classified by Mission • Attack • Missile

  7. Research Submarines • Submersibles • Smaller • Carries 2 to 3 scientists

  8. Tourist Submarines

  9. Atmospheric Diving Suit • Resemble space Suits • One person Submersible • Expensive to maintain

  10. 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.

  11. Unmanned Vehicles • ROVs • AUVs • Hybrid Vehicles

  12. ROVs • Free-Swimming • Bottom Crawling • Structurally Reliant

  13. Free Swimming ROVs • All are tethered • Tether provides, power and data • Equipped with video/TV Cameras • Highly maneuverable

  14. Free Swimming ROVs • Heavy Duty Work Class • Work Class • High-Capability Electric • Small (electric) ROV Observation Class

  15. Heavy Work Class They primarily service the oil and gas industry 225 Horsepower - 2900 pounds of vertical lift Multiple heavy tools

  16. Work Class Millennium Electro-Hydraulic 100-200 HP Drilling support, Construction, Pipeline or Inspection

  17. High-Capability Electric • Compact work class system • Not as powerful as hydraulic • 2000-4000 lbs • Payload 220-440 lbs • Depth capacity to approximately 3,000’

  18. Small (electric) ROV(Observation Class) • Lower Cost • Usually less than 10 HP • Used for inspection • Observation • Search and Rescue • Scientific Exploration

  19. Bottom Crawling ROVs 500 Horsepower Cable and Pipeline, Trencher • Large • Heavily Weighted • Used for trenching and burying cable

  20. Structurally Reliant ROVs • Attached to various types of underwater structures • Used for cleaning or inspecting structure they are attached to

  21. AUVsAutonomous Underwater Vehicles • Tether less • Carries own power • No pilot • Pre-Programmed • Easy Launch and Recovery

  22. Gliders • Require less stored energy

  23. Hybrid Vehicles • Nereus • Can be operated as an ROV or as an AUV • http://www.whoi.edu/home/interactive/nereus/

  24. Non-Vehicles • Underwater Habitats • Tow fish • Anchored Platforms

  25. Underwater Habitats

  26. Tow fish

  27. Anchored Platforms
