Offshore operation monitoring device

The utility model discloses an offshore operation monitoring device which comprises a safety helmet, a processor, two first distance sensors and a plurality of second distance sensors, and the processor is embedded in the front side of the safety helmet. According to the utility model, when the first distance sensor gives an alarm due to short distance, an alarm signal is transmitted to the processor, then the processor controls the movable end of the three-section electric push rod to contract, the gear indirectly descends to the position of the inverted T-shaped gear sleeve connected with the second video monitoring host, and then the motor is started; the inverted-T-shaped gear sleeve drives the supporting plate and the second video monitoring host which are connected with the inverted-T-shaped gear sleeve to rotate, when the second video monitoring host arrives at the front side of the safety helmet, a pilot can know the position of the ship body through a monitoring picture, then the pilot enables the sh
