Abstract
The top and bottom angles of a marine riser are of crucial importance during e.g. drilling and workover operations. A ver- tical position control with active heave compensator (AHC) is proposed to maintain the safety of the riser when subjected to environmental excitations. The possibility of reducing the maxi- mum angular response level by adjusting the vertical rod position by means of an active heave compensator is investigated with a positioning algorithm based on adaptive backstepping.
Riser top and bottom angles are dealt with by the algorithm in order to minimize both angles.
