  • Propellant energy to operate subsea equipment
    Patent number: 9863202
    Abstract: Systems and methods for using propellant as a force generator in component actuation are disclosed. One embodiment may take the form of a method including deploying at least one component to a subsea location, controlling operation of the at least one component using a control system, and igniting a propellant. The ignition of the propellant actuates the at least one component. Another embodiment may take the form of a subsea system including a control system, a propellant system in communication with the control system, and a component in communication with the propellant system. The propellant system is ignitable by the control system upon receipt of a ignite signal and upon losing communication with the control system after being placed in an armed state by the control system. The component is actuatable by the propellant system after ignition of the propellant system.
