Releasing device and releasing method for underwater beacon used for dynamic positioning system sea trial

Abstract

The invention provides a releasing device for an underwater beacon used for dynamic positioning system sea trial. The releasing device for the underwater beacon used for the dynamic positioning system sea trial comprises the underwater beacon, a first connecting piece, a second connecting piece, a buoy, a first pressed iron and at least two second pressed irons, the first pressed iron is connected with the bottom of the underwater beacon, the two ends of the first connecting piece are correspondingly connected with the first pressed iron and the second connecting piece, the buoy is connected with the second connecting piece, and all the second pressed irons are connected with the first connecting piece correspondingly. According to the releasing device for the underwater beacon used for the dynamic positioning system sea trial, the structure is simple, using is convenient, position of the underwater beacon in the seafloor can be determined according to the method for water surface buoy positioning, the length of ropes needed to be released is determined according to boat length, boat width, water depth for the trial and area of water area for the trial, the method for manually releasing and refloating the underwater beacon is set, and safety of the whole trial process is guaranteed. The releasing method for the releasing device is simple in operating process, reliable in principle, and high in safety.

Description

technical field [0001] The invention relates to an underwater beacon launching device and launching method for sea trials of a DP system. Background technique [0002] Dynamic positioning system (Dynamic positioning system) referred to as DP system refers to the technology that the propeller is automatically controlled by the shipboard computer to maintain the position of the ship or floating platform without anchoring. It uses sophisticated and advanced instruments to measure the displacement and direction changes of the ship or platform due to the collected surrounding environmental factors such as water flow, wind speed, wind direction, sea waves, etc., and processes and calculates the information in real time through automatic control systems such as computers. , and automatically control the thrust and torque of propellers in several different directions, so that the ship or platform returns to its original position. Underwater beacons refer to electronic modules that ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the sea trial process of the DP system, the underwater beacon launch basically adopts the automatic release of the equipment itself and the recovery of the small boat. After the beacon is set, the underwater beacon is no longer under the control of the trial ship. If the current is strong or the wind is strong, the recovery boat will not be able to catch up with the underwater beacon, and it will also threaten the recovery boat. The personal safety of the personnel on board will largely cause the loss of the underwater beacon, resulting in property loss; in addition, due to the failure of the automatic release device of the underwater beacon, it will also cause the inability to carry out the underwater beacon. The result of recycling

If these situations occur during the test process, the test will be interrupted, which will affect the sea trial period of the ship and increase the risk and cost of the ship sea trial process.
