Abstract:
The present invention relates to a riser joint for a riser with a joint connecting two parts of a riser where the two parts are allowed angular displacement. According to the invention the riser joint comprises means for connection to the two parts of the riser at a distance from the joint, and means for adding a force between the two parts. The invention also relates to a method for reducing bending moments in a riser at a connection between the riser and a subsea installation.
