A method for determining a position of a fluid discharge in an underwater environment, the method including: collecting data relating to an underwater area through at least two acoustic sensors; filtering and processing the data collected to identify the presence of the discharged fluid and the underwater area involved; forming a single stereoscopic image by combining the plurality of single three-dimensional images; and estimating the position of the fluid discharge on the basis of the stereoscopic image thus obtained.

A combined piloting method of remote operated underwater vehicles includes: connecting, to a vertical profile, a constraint device including at least two arms arranged at a reciprocal fixed angular position, each of the at least two docking arms including at a first end a device for the hooking of a remote operated underwater vehicle, the at least two docking arms being constrained at one of their second ends to a device for the sliding and rotating hooking to the vertical profile; connecting at least two remote operated vehicles to the constraint device; detecting the position of the overall structure consisting of the constraint device and remote operated vehicles; detecting the orientation of each of the remote operated vehicles; receiving data relating to the position and orientation to be reached; determining the power required by each remote operated vehicle; and transmitting related commands to each vehicle.
