Abstract: The present invention refers to a device for sensing photoluminescent materials, said device comprising at least a source of light configured to generate a beam of light that is transmitted to the outside of said device and hits a photoluminescent material; a photon counting detector configured to receive a response light generated by the illumination of photoluminescent material with said beam of light and convert it into an electrical signal; a signal processing electronic system configured to process said generated electrical signal; and a signal transmission means configured to transmit the signals generated by the said signal processing electronic system towards the outside of the said device.

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.
