Abstract

The invention relates to a telescopic riser joint for connecting a first riser part and a second riser part, the riser joint comprising: a first pipe part (8) and a second pipe part (9) comprising means for connection to the first riser part and the second riser part respectively, which first and second pipe parts in use are arranged to form part of a riser with an internal flow passage, a cylinder arrangement comprising a first set of cylinders (32), each cylinder having a piston rod with a piston head (51) and a cylinder housing, the piston rod and cylinder housing being respectively connectable to one of the first pipe part or second pipe part, wherein one side of the piston head in use is in communication with external pressure providing an axial force acting in the longitudinal direction of the riser, and the other side of the piston head is facing a sealed chamber (52), where the cylinder arrangement is configured such that a fluid in the sealed chamber and a fluid on the other side of the piston head give a resultant force tensioning the first riser part and the second riser part.
