TheScorpio (Submersible Craft for Ocean Repair, Position, Inspection and Observation) is a brand of underwater submersibleRemotely Operated Vehicle (ROV) manufactured byPerry Tritech used by sub-sea industries such as theoil industry for general operations, and by theRoyal Navy and theUnited States Navy forsubmarine rescue services. Originally developed byAMETEK Straza ofEl Cajon, California, they were subsequently developed byPerry Tritech. Although the design of the original Scorpio is over several decades old, it forms the basis for a current generation of Scorpio-branded ROVs. Scorpio ROVs are named in a sequence following the order of manufacture, such as "Scorpio 17" or "Scorpio 45" which refer to specific ROVs.
The UK operates a Scorpio 45, based at the Australian Submarine Rescue Service headquarters in Perth, Western Australia. It carries three remote cameras, two manipulator arms (including cutting equipment), one Sonar device and six 250Watt lights. It is operated by James Fisher Defense who provide the underwater rescue service to the RAN. The vehicle is deployed along with a control room, built into a standard shipping container.
Delivered to the U.S. Navy in 1987, the Super Scorpio is a "Tethered Unmanned Work Vehicle System". The vehicles are used for the recovery of sunken military and commercial hardware. They feature two cameras, a sonar, six lights and two robotic arms. The arms can cut steel cable up to one inch (2.5 cm) thick and lift up to 250 pounds (113 kg) each. The sonar has a range of 2,000 feet (610 m).
Scorpio vehicles were sent to assist in the rescue of theKursk, a RussianOscar II class submarine which sank on 12 August 2000. Unfortunately, they were unable to save any of the 118 crew.
In 2002,High Performance Wireless Research and Education Network researchers conducted an expedition to locate theSEALAB II/III habitat located off Scripps Pier inLa Jolla, California.[1] Researchers utilized a Scorpio ROV from the MVKellie Chouest to find the site and were able to conduct a livemulticast from ship to shore.[1] This expedition was the first return to the site since the habitat was moved.[1]
Both the UK and U.S. sent Scorpio vehicles to the location of aRussianPriz class submersibleAS-28 trapped on the sea floor off theKamchatka Peninsula on 5 August 2005.
The UK vehicle flew on aC-17 to the incident with a team of 28 including police officers, civilian operators and one member of theRoyal Navy, Commander Ian Riches. Two U.S. vehicles and 40 support personnel were sent fromNaval Air Station North Island, nearSan Diego, via aC-5 Galaxy transport to Kamchatka. Both the UK and U.S. equipment and teams were transported by Russian surface ships to the accident scene. The British Scorpio managed to free the trappedAS-28 on August 7, 2005, allowing the Russian submersible to surface and saving all seven crew members on board. The American ROVs arrived two hours after the British crew and assisted them.
