First ever survey “ROV”
A brief review…
• Dimitri Rebikoff (1921-1997)
• 1952-1954: Development of the first underwater scooter, the “Torpille”, which later became the world´s first remotely operated underwater vehicle, the “Poodle”.
• “http://www.rebikoff.org/History/history.html”
• Three servo-control systems for pitch, yaw and roll
• Equipped with camera, magnetometer and sonar.
• Reached 700 feet.
• Primarily used for archeological research

Early WROVs used for survey in the North Sea
A brief review…
1982: • Two new Scorpio ROVs ordered by Stolt Nielsen
Seaway Submersibles, equipped with the following: • Robertson Subsea Gyro sn 001 og 002 • Liebnitz Lann 3ch PAL videomultiplexer • Osprey SIT camera • 3 x Sony Studio Color Cameras (each 3 tubes),
rebuilt for genlock sync • Side cameras mounted on foldable booms to be
able to get through moonpool. • Corrintec rotating CTD probe • Digiquarz depth sensor • Altimeter • Side scan sonar • Sub bottom profiler
• SSS og SBP were taken from towfish and mounted on ROV, unsure about fabrication
• Amatek Obstacle Avoidance Sonar • Superumbilical med 4 coax og 3 quads.
SCORPIO (Submersible Craft for Ocean Repair, Positioning, Inspection and Observation), built by Ametek, Straza, USA, has a depth capability of 1000 m and is fitted with a 5 function manipulator. Launched in 1978.

On Friday 10th July the SUPERIOR took its first dive from the Volstad Surveyor
Over the next days acceptance tests were undertaken by the Kystdesign engineer onboard to make sure the ROV was in perfect working order for DeepOcean.
Following these tests DeepOcean performed various tests for survey and ROV purposes.
