Claim:
1. A safety device for protection of the integrity of well barrier(s) or other interfacing structure(s) at an end of a riser string or a hose, the safety device comprising a releasable connection in the riser string or hose, the releasable connection arranged to release or disconnect during given predefined conditions in order to protect the well barrier(s) or other interfacing structure(s), wherein the safety device comprises: at least one sensor to monitor at least one of tension loads, bending loads, internal pressure loads and temperature, where said at least one sensor is arrangeable on a segment of the riser or hose, and where said at least one sensor is adapted to provide measured data relating to at least one of tension loads, bending loads, internal pressure loads and temperature, an electronic processing unit adapted to receive and interpret the measured data from said at least one sensor, an electronic, hydraulic or mechanical actuator or switch arranged to receive a signal from the electronic processing unit and initiate a release or disconnect of the releasable connection, wherein the electronic processing unit is configured to autonomously send the signal to the electronic, hydraulic or mechanical actuator or switch when the measured data is indicative of the given predefined conditions.
