Abstract: A test system and method for a marine vessel dynamic positioning system comprising a control system (2) arranged for receiving real measurement signals (7) from sensors (8) and for output of control signals (13) to actuators (16, 17, 18). The test system comprises a signal modifying computer (80) arranged for receiving real measurement signals (7), modifying the real measurement signals (7) into modified measurement signals (70) that depend on real values of the real measurement signals (7), and sending the modified measurement signals (70) to the control system (2), wherein the modified measurement signals (70) replaces the real measurement signals (7), so as for enabling testing of the control system (2) on errors represented by the modified measurement signals (70).

Abstract: The invention relates to a method for testing a control system (5) of a marine vessel (0). The control system (5) receives input commands (51) like desired position, heading, and speed from an input command device (50). The control system sends control signals (6, 62) to actuators (3). Such actuators may be electrical thruster drive motors (32) for thrusters (31) and electrical propeller motors (35) for fixed-shaft propellers (34). The vessel (0) comprises sensors (8) like position reference sensors (81, 82, . . . ) providing sensor signals (7, 71, 72, . . . ) back to said control system (5). The actuators (3) receive electrical energy provided by an on-board power system (1) that is controlled by a power management system (2).
