DESIGN AND SIMULATION OF A DYNAMIC POSITIONING SYSTEM FOR A U.S. COAST GUARD BUOY TENDER

This paper covers the design of a dynamic positioning system for the U.S. Coast Guard WLB "IRIS" class buoy tender. The control system design is based upon optimal control theory with estimates of position and heading provided by a steady state Kalman filter. Sea current estimates are provided by a Kalman filter predictor based upon the innovations process. The vessel and dynamic positioning system are simulated using the Dynamic Simulation Language (DSL). The computer-based dynamic positioning system is proven to be a viable alternative to manual position-keeping methods under environmental conditions up to sea state 5, current up to 1.5 knots, and wind up to 30 knots.
