A Deep-Ocean Exploration ROV For the Okeanos Explorer Justin Manley NOAA Ocean Exploration (Battelle) Justin could not travel this week and sends his apologies. Contact info will be provided at the end if you have detailed questions for him.

Dedicated ROV Goals Provide a permanent ROV capability to the Okeanos Explorer Winch and control room integrated into vessel Link to satellite telemetry Support the exploration/reconnaissance mission High reliability over long deployments Ease of maintenance and upgrades Adaptability to many science tasks rather than focus on one Budget conscious program Protracted investment over time Leverage other Federal investments Capitalize on industrial experience

ROV System Requirements 6,000 meters operating depth Two body (Camera platform and ROV) system operating on 7500m of Rochester 2351 cable sled and ROV connected via 150-300 ft tether High Definition cameras “Telepresence” interface Closed-loop control: auto-depth, heading, X-Y Size appropriate to vessel ROV < 12’ x 8’ x 8’ & 7,000 lbs ROV payload capacity of 250 lbs

Camera/Lighting “Sled” Design Robust design Significant passive stability ROV tether “quick disconnects” with 5x ROV weight rating Ease of use No thrusters reduces operator burden HD Camera 360° pan, 180° tilt provides for wide view Can stand alone Considering alternative frame layout for better lighting in this mode Interface for additional sensors May support a micro-ROV Image courtesy Phoenix International

ROV Design Typical deep ROV evolved to focus on imaging Improved light/camera separation Adequate room to pan and tilt HD camera (primary factor affecting mechanical design) HD cameras drive the “systems” Includes workskid interface Versatile design for payload “modules” Image courtesy Phoenix International

Micro-ROV for additional views and enclosed spaces NOAA ROV xBot Gen 3 Micro-ROV for additional views and enclosed spaces Gen 3 offers increased modularity for ease of Upgrade Repair Assembly Improved maintainability
