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

Auxiliary subsurface compensator

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.
