DYNAMIC POSITIONING SYSTEM CONSIDERING MOVEMENT OF ROV AND DYNAMIC POSITIONING METHOD OF THE SAME

摘要

The present invention relates to a dynamic positioning control system considering a movement of a remotely operated vehicle (ROV), and a positioning control method thereof capable of preventing a loss or damage to the ROV by automatically controlling a position of a ship in accordance to a movement of the ROV using sound wave signals generated from the ROV. According to an embodiment of the present invention, the dynamic positioning control system to control a plurality of positioning devices installed in the ship comprises: a sensor part to measure information on the position of the ship; the ROV having a sound wave generator to generate sound wave signals, and to perform seabed exploration; a sound wave receiver to receive the sound wave signals generated from the sound wave generator; and a central control device outputting a thrust control signal to control the position of the ship using the information measured by the sensor part to the positioning devices, and controlling the position of the ship in accordance to the distance between the ship and the ROV grasped using a sound wave generation time at which the sound wave generator generates the sound wave signals, and a sound wave reception time at which the sound wave receiver receives the sound wave signals.
