A tool (100) is described for removing unwanted gas hydrates from the surface of equipment used in subsea exploration and production, with the said tool being comprised of a main vessel (1) and a power cable (2) linked together by a connector (3); and, inside the said vessel (1) a laser device (15) is connected to an adjustable focus collimator (4) by a cable (12), with the wavelength emitted by the said laser (15) being between 200 nm and 930 nm, whereby when the radiation reaches the subsea exploration equipment it causes the heating thereof, which in turn heats the hydrate through conduction, breaking down the hydrate formation from the inside out; and with the front lid (14) having a window (5) forming an interface between the said vessel (1) and the aqueous medium, with the said window (5) being fitted with anti-reflection film (6) and anti-reflection film (7). The method for removing gas hydrates from the surfaces of equipment used in subsea exploration and production with the assistance of the said tool (100) is also described. |
