Abstract
The invention relates to a safety joint and a method of operation, the safety joint comprising: a first riser part and a second riser part overlapping in an axial direction and having end connections to be connectable as part of a riser, a release unit, locking the two riser parts together in a not activated mode, the release unit having other modes comprising a partly activated mode and fully activated mode, where the release unit comprises at least one axial extending tension rod connected between the two riser parts, which tension rod is configured to deform plastically before breaking, thereby activating the partly and fully activated modes.
