Abstract

The invention relates to a triggering mechanism for a triggering valve 1 of a hydraulic emergency unlock circuit for unlocking hydraulically operated gripping members of a riser connector which connects a lower end of a riser 2 to a wellhead on a sea floor. The triggering mechanism comprises a cam ring 5 secured to a displaceable part 4 of a flex joint for the riser 2, and an actuator ring 8 which by means of hydraulic cylinders are translatory movable towards a stationary part 3 of the flex joint. An angular displacement alpha of the riser 2 causes an angular displacement alpha of the cam ring 5, which contacts the actuator ring 8 and forces the actuator ring 8 towards the stationary part 3 of the flex joint, causing an activating of a trigger 13 for the triggering valve 1.
