  • Patent number: 5839383
    Abstract: A gas storage system formed of a continuous pipe wound in plural layers, each layer having plural loops. The pipe may be distributed within a container, which may serve as a carousel for winding the pipe and as a gas containment device. When containers, each containing a continuous pipe are stacked upon each other, the weight of upper containers may be born by the walls of lower containers, thus preventing lower layers of pipe from suffering stresses due to crushing by upper layers. A method of transporting gas to a gas distribution facility including obtaining a supply of gas at a gas supply point remote from the gas distribution facility, injecting the gas into a continuous pipe bent to form plural layers, each layer including plural loops of pipe, transporting the continuous pipe along with the gas to the gas distribution facility preferably in a ship and discharging the gas at the gas distribution facility.

  • Patent number: 5803005
    Abstract: A ship based system for compressed natural gas transport that utilizes a ship having a plurality of gas cylinders. The invention is characterized by the plurality of gas cylinders configured into a plurality of compressed gas storage cells. Each compressed gas storage cell consists of between 3 and 30 gas cylinders connected by a cell manifold to a single control valve. A high pressure manifold is provided including means for connection to shore terminals. A low pressure manifold is provided including means for connection to shore terminals. A submanifold extends between each control valve to connect each storage cell to both the high pressure manifold and the low pressure manifold. Valves are provided for controlling the flow of gas through the high pressure manifold and the low pressure manifold.
