Impact of Offshore Mooring on the Startup of ESGM

When the electrostatic support gyro monitor(ESGM) is started at sea in emergency, the real-time working condition of the ship has a great influence on the accuracy of system. If the disposal is not timely, the accuracy will be rather low, to the extent that the monitor will not be successfully started. In the case of poor weather, the stars cannot be measured by theodolite. This will directly affect the course accuracy provided by the test missions. In this paper, by reviewing the electrostatic starting process of mooring near the offshore dock, the specific causes of the poor starting calibration are analyzed. What’s more, the processing method of the bad state in 48-hour calibration stage is defined, and the ship maneuver selection method with faster change of electrostatic ship starting course is supplemented. This has certain reference significance for reducing risk of the test missions.
