FIELD: oil and gas industry.
SUBSTANCE: method for development of methane hydrates is based on their breaking by water jets at a temperature of more than 285K with the rate more than 1 m/s in a pulse mode with a frequency in the range from 1 up to 200 Hz, gasification and lifting from the seabed. A device for development of methane hydrates contains a floating device, handling equipment, a power generating unit, pipelines, a control unit and an underwater methane hydrate development unit in which body there is an installed infrared heater, a water-jet monitor with pressurised water feed equipment and a gas bleeder.
EFFECT: improvement of energy efficiency for underwater development of methane hydrates and their lifting to the floating device.
