 Abstract
The Underwater Remote Controlled Vehicle, surface linked
by means of a umbilical cable, acts under marine current
influence which represents the main perturbation force of
its movement. In the present paper is made a shape analysis
which gets the cable and aso of vehicle movement in the time
period of a inspection mission at vertical underwater struc-
tures. The mathematical approach is aimed to obtain design
elements regarding force, direction and time necessary to
movement correction with the help of the vehicle propulsion
unit.
