Abstract:
A method and equipment for harvesting natural gas from seabed hydrates are disclosed. The preferred equipment includes a mobile riser, a water injection nozzle, a gas collector, a gas separator, a gas compressor, a water pump, and a water boiler. A fraction of produced gas is used to heat water which is in turn injected to seafloor for dissociating gas hydrates. The preferred method of the invention comprises producing natural gas from seabed hydrates using a production ship with a moving riser installed. This method eliminates the need of drilling wells and thus cuts cost of gas production tremendously.

Claim (Index 7):
A method for dissociating gas hydrates on the seabed comprising injection of hot water containing hydrate inhibitors through a riser assembly wherein said riser assembly comprises an inner pipe and an outer pipe.
