A method for the extinction or oil well-killing or killing of an underwater well for the extraction of hydrocarbons under uncontrolled fluid discharge conditions, also called blowout, by assembling, in correspondence with the lower end portion of a string of pipes for the extinction or killing string, a constraint group for rigid connection between a plurality of remote-operated underwater vehicles and the killing string; detecting the position of a flow of fluids and positioning the killing string substantially in correspondence with said flow; lowering a plurality of remote-operated vehicles close to the lower end portion of the killing string; connecting the remote-operated vehicles to the constraint group; detecting in real time the relative position of the flow of fluids with respect to the vehicles and calculating the position of the outlet hole of the flow; on the basis of the calculated position of the outlet hole, coordinately piloting the vehicles so as to bring the lower end of the string in correspondence with the position of the outlet hole of the flow. |
