A brief review First ever survey ROV 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
A brief review First ROV with manipulator - CURV? 1965 CURV 1 Developed by US Navy

A brief review
A brief review Early WROVs used for survey in the North Sea 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. 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.
A brief review SOLO ROV 1 st ROV purpose made for survey SOLO: 1984 Built by Slingsby Engineering Limited on order from Stolt Nielsen Seaway Work class ROV with 4 horizontal thrusters Fibreglass frame Fibreglass electronics bottle 1,2m dia x 2,5m (!) First with fiber-optic data transmission system
A brief review 1998-2000 HiROV 3000 4 x MK I delivered to InterROV/Seateam in 1998 2 x MK II delivered to DeepOcean in 2000. 125 HP Hydrodynamic shape Removable survey frame to maintain MBE calibrations Speed approx. 3 knots

Acceptance Testing 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. SUPERIOR ROV WITH SKID REMOVED FOR SEABED MAPPING SURVEYS
SUPERIOR ROV WITH SKID ATTACHED FOR PIPELINE SURVEY
SUPERIOR ROV WITH SKID DETATCHED FOR HIGH FLY APLICATIONS
SUPERIOR ROV READY FOR DEPLOYMENT
Results of early testing Near perfect station-keeping Ability for ROV to follow predetermined.rlx runline Pipeline Survey speeds up to 3.46 Knots Seabed Mapping speeds up to 5.31 Knots (a new DeepOcean survey record) all with just 1 of pitch and -2 roll constant.) Ability to increase on these survey speeds and motions with some thruster tweaking from Kystdesign 6 very happy ROV pilots!
