Abstract
A method for producing hydrocarbons wherein hydrates are excavated from the sea bottom and mixed into a transportable slurry, the slurry being pumped to a support vessel, using near sea bottom positive displacement hydraulic pumps, where the hydrates are converted into a hydrocarbon containing stream, with excavation tailings being pumped down to hydraulic motors to drive the hydraulic pumps.
