Abstract

A safety device and method for protection of the integrity of well barrier(s) or other interfacing structure(s) at an end of a riser string or a hose includes 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). The safety device safety device includes at least one sensor to monitor at least one of tension loads, bending loads, internal pressure loads and temperature. The sensor provides measured data relating to at least one of tension loads, bending loads, internal pressure loads and temperature. An electronic processing unit receives and interprets the measured data from the sensor. An electronic, hydraulic or mechanical actuator or switch is arranged to receive a signal from the electronic processing unit and initiate a release or disconnect of the releasable connection.
