Abstract

A special installation of a riser (10) that extends between an item of subsea equipment (14) and a surface vessel (12) has been described, which installation in particular is intended for use in connection with offshore oil extration, and in which the rise (10) is provided with a telescopic section. For the purpose of heave compensation, the riser (10) is installed in a manner such tat said telescopic section (18) is located at the lower end of the riser (10), heave compensation being effected by the telescopic mobility of the riser (10), while the mass of the riser (10), when suspended in this manner, keeps the rise (10) tensioned.
