Claim Text:
1. A tubing mounted completion assembly comprising: at least one downhole valve assembly comprising a primary valve actuator, and a plurality of contingency devices associated with and separate from the downhole valve assembly, each of the plurality of contingency devices arranged in series in a tubing with the downhole valve assembly, wherein each contingency device is adapted to actuate the downhole valve assembly upon failure of the primary valve actuator to actuate the downhole valve assembly, and at least one of the plurality of contingency devices comprises a mechanically-actuated contingency device and at least one of the plurality of contingency devices comprises a hydraulically-actuated contingency device, the mechanically-actuated contingency device and the hydraulically-actuated contingency device being independently coupled to the downhole valve assembly by respective conduits containing fluid, such that actuation of either the mechanically-actuated contingency device or the hydraulically-actuated contingency device causes displacement of a sealed hydraulic fluid to actuate the downhole valve assembly.
