摘要： 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.

摘要： The present invention regards a joint for use in a riser (1) extending between a floating installation (3) and a subsea installation (2). The joint comprises an inner pipe segment (21) and an outer pipe segments (22), arranged moveable relative each other in an axial direction and connectable to respective riser segments, forming a chamber (23) between them with a radially extending piston (24), dividing the chamber (23) in a first chamber part (25) and a second chamber part (26), wherein on of said chamber parts (25) in an initial position of the joint is adapted to contain a mainly incompressible fluid, this chamber part (25) decreasing in volume as the inner pipe segment (21) is moved relatively out of the outer pipe segment (22). According to the invention the joint is configured with a fluid line connection (30) from said one chamber part (25) to the other chamber part (26), configured such that the relative movement of the pipe segments (21, 22) is controlled by the allowed flow rate of a fluid flowing out of the chamber part (25) through the fluid line connection (30) to the other chamber part (26).
