MODERN CONTROL THEORY FOR DYNAMIC POSITIONING OF VESSELS

The present range of ALBATROSS dynamic positioning systems from A/S KONGSBERG VAPENFABRIKK is based on the use of modern control theory and Kalman filtering, in order to give smooth optimal control to offshore work vessels using a variety of measurement systems. The control system principles are presented in the paper together with the system performance on board several vessels using different measurements systems. The paper also deals with an extension to the system providing mooring assisted DP. This combination system has a great potential for providing stable positioning in deep water as well as under severe weather conditions. The anchor parameters are estimated on-line to avoid complex and costly measurement techniques.
