Abstract Using Monte-Carlo simulations and experimental model tests, the performance of three controllers designed for dynamic positioning (DP) of marine vessels and offshore rigs subjected to the influence of sea waves, currents, and wind loads is compared for different sea conditions: calm, moderate, high, and extreme seas. The first controller is a nonlinear multivariable PID with a passive observer. The second controller is of the Linear Quadratic Gaussian (LQG) type and the third… CONTINUE READING
