Abstract
Gas storage is provided for a subsea gas-lifted riser during offshore drilling and/or production operations. One or more gas storage chambers positioned along and about the subsea riser are connected to a gas conduit. Each chamber has at least one valve for controlling passage of gas out of the chamber and into the gas conduit. The valves serve to allow the gas from the storage chambers to be injected as lift gas as needed.
