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.

Abstract: The invention relates a cylinder release arrangement, wherein at least one cylinder is arranged with a piston within the cylinder, and a cylinder head closing off one end of the cylinder, forming a chamber between the piston and the cylinder head, wherein the cylinder is provided to arrange a leakage of fluid from one side of a piston to the other side of the piston, when the piston is in a given position within the cylinder, and release means are provided for the subsequently controlled release of the cylinder head from the cylinder. The invention also comprises a cylinder arrangement with a release mechanism.
