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.

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: Force-dampening arrangement (100) for dampening forces between two interconnectable parts in a tube string, of which interconnectable parts a lower part (101) is connected to the upper end of a string element (105, 3a) extending into a subsea well (5) and an upper part (103) is suspended from a floating surface installation (1) through at least one suspension element (3b) extending up to said surface installation. The force-dampening arrangement (100) is connected to the tube string above a string-portion (3a) extending into said subsea well, and below at least a portion of said suspension element (3b). The force dampening arrangement (100) exhibits an upper and lower section (109, 111) that are vertically movable in relation to each other, thereby yielding for impact forces between said interconnectable upper and lower parts (103, 101) resulting from vertical heave movement of said portion of suspension elements (3b) moving vertically in respect of the string element (3a).

Abstract: An actuator for a motor vehicle transmission has a shift cylinder performing rotary actuating movements. An electric motor is arranged inside the shift cylinder and drives the latter either through a harmonic drive mechanism or a planetary drive mechanism. The arrangement provides a high reduction ratio and an efficient use of limited space.
