Abstract
The present invention relates to a heave compensator for a riser, particularly a working riser (9), comprising a telescopic connection (10) with a first chamber (60) which is in fluid connection with the interior of the riser and a second chamber (62) which is connected with a source of pressure fluid. By varying the pressure in the second chamber in response to the movements of the platform, the telescopic connection can be arranged to move in correspondence with the platform's movements, thereby permitting access to the riser during working operations.
