Abstract
The invention provides a system and method for controlling packer activation in a riser slip joint. The system comprises a first electronically actuated valve disposed between a first packer and a fluid pressure source for the actuation of the first packer. A second electronically actuated valve is disposed between a second packer and a fluid pressure source for the actuation of the second packer. A control unit is operable to actuate the first and/or second electronically actuated valve in response to at least one input signal to control the activation of the first and second packers, and is configured to control the actuation of the first and second electronically actuated valves independently.
