  • Patent number: 10046415
    Abstract: A tool and related method for removing unwanted gas hydrates from the surface of equipment used in subsea exploration and production. The tool includes a main vessel and a power cable linked together by a connector. Inside the vessel a laser device is connected to an adjustable focus collimator by a cable, with the wavelength emitted by the laser being between 200 nm and 930 nm. 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. The front lid of the tools includes a window fitted with anti-reflection film that forms an interface between the vessel and the aqueous medium.
