Latest Patents
Carman holds a patent for a "Method and apparatus for remote control of an underwater valve." This invention provides improved techniques for opening or closing an underwater valve in a subsea fluid pipeline. The method utilizes an acoustic signal transmitted from the surface to a receiver adjacent to the valve. A predetermined torquing force is applied to a shaft directly coupled to the valve stem, while the rotation of the valve stem is initially prevented by a mechanical connection of an explosive bolt. Upon receipt of the transmitted acoustic signal, stored electrical energy is released, detonating the explosive bolt and breaking the mechanical connection. This process enables the pre-existing torquing force to rotate the valve stem, significantly increasing the reliability of valve operation.
