This paper discusses the development of an innovative method of improving DP positioning accuracy using only sensors and control algorithms. Based on the estimation of wave drift forces using wave height sensing and the application of a wave feedforward control loop, the positioning of a vessel in a seaway is improved. This technique is also applied to the challenge of controlling two large vessels, running alongside, at ahead speeds.
