Jason (ROV)
''Jason'' is a two-body remotely operated vehicle (ROV) designed, built, and operated by the National Deep Submergence Laboratory of the Woods Hole Oceanographic Institution (WHOI). Construction of ''Jason'' began in 1982 and was first launched in 1988, redesigned in 2002 as the second iteration of the ROV (''Jason II''). The ROV allows scientists and explorers to have access to the seafloor without leaving the deck of a ship. As of 2020, ''Jason'' has completed 147 cruises with over 1200 dives and over 16,000 hours of dive time. Construction and Equipment Development on ''Jason/Medea'' began in 1982, with the goal of removing constraints of human operated vehicles such as ''Alvin''. ''Alvin'' only had 3-4 hours of time on the seafloor, required extensive and expensive planning for safety purposes, and required a sophisticated handling system for such a large vehicle. ''Jasons original commission was in 1988, with a deployment at Hood Canal in Washington state, USA. The firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remotely Operated Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimize ...

Jason Jr
Jason ( ; ) was an ancient Greek mythological hero and leader of the Argonauts, whose quest for the Golden Fleece featured in Greek literature. He was the son of Aeson, the rightful king of Iolcos. He was married to the sorceress Medea. He was also the great-grandson of the messenger god Hermes, through his mother's side. Jason appeared in various literary works in the classical world of Greece and Rome, including the epic poem ''Argonautica'' and the tragedy ''Medea''. In the modern world, Jason has emerged as a character in various adaptations of his myths, such as the 1963 film '' Jason and the Argonauts'' and the 2000 TV miniseries of the same name. Persecution by Pelias Pelias (Aeson's half-brother) was power-hungry and sought to gain dominion over all of Thessaly. Pelias was the progeny of a union between their shared mother, Tyro ("high born Tyro"), the daughter of Salmoneus, and the sea god Poseidon. In a bitter feud, he overthrew Aeson (the rightful king), killin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
