摘要： The present invention relates to a method and a safety device for protection of well barrier(s) (5) against excessive bending moments from a riser (2). The safety device according to the present invention is arranged to detect critical bending loads in or in between the well barrier(s) (5) and/or riser (2), and may comprise: means for detecting changes in a curvature between a load carrying riser pipe (2) and an unloaded stiff body (18) attached to or in the vicinity of the riser pipe (2), said means for detecting changes in the curvature being arranged to measure a relative distance (d) between the load carrying riser pipe (2) and the unloaded stiff body (18), and means for triggering disconnection of a releasable riser connector (6) when the distance (d) between the load carrying riser pipe (2) and the unloaded stiff body (18) reaches a predefined critical distance (d c ).
