This paper describes the performance of a position measuring system using angle measurements at the top and bottom of the marine riser to overcome the deep water accuarcy and stability problems encountered with taut wire and bottom ball joint angle measurement systems. Computer analyses have shown that the system described yields position errors of 1 percent or less of water depth for water depths of up to 1829 M(6000 ft). These analyses have indicated that the concept is feasible for greater depths.
