Small Vehicles
Small vehicles includes the majority of "low-cost"
ROVs (LCROV), most of which are typically all electric and nominally operate to water
depths of 984 feet (300 meters). These vehicles are used primarily for inspection
and observation tasks. There has been a recent surge in the development of small
vehicles, due primarily to the improvement in technology for electrically powered
systems. These improvements have resulted in an increase of capability, performance
and depth not previously achieved.
"Low
cost" is relative and vehicles in this class sell in the $10,000
to over $100,000 range, however, vehicles like the Quest LCROV
(right) and Hydrovision’s HyBall (below) are cheap when compared
to larger work class ROVs. Today's LCROVs are used widely for many tasks
including science, marine recreation, search and rescue; dam, waterway
and port inspection; training, shipping, nuclear inspection and coastal
offshore inspection and observation tasks.
The
Low Cost ROV (LCROV) first appeared on the market in 1981 with International
Submarine Engineering's RASCL, which cost about $45,000. In 1984
the MiniROVER, built by Deep Sea Systems International was introduced
at a price of $28,600. In 1985 Deep Ocean Engineering offered the Phantom
at about $30,000. By 1990, 35 versions of LCROVs could be counted, being
built by 27 different manufacturers with over 500 systems delivered.
Today they account for approx. 22% of all ROVs.
