Description

  The present invention relates to a anchoring position management system, and more particularly, to an anchoring position management system that allows anchoring or anchor wires between work ships to be safely thrown in a work area where a plurality of work ships work. It is.

  When working with a work boat kept at a fixed position on the water, anchors are dropped on the bottom of the water and anchored, but in a work area where multiple work boats work, each work ship is a It is necessary to drop the own anchor so as not to interfere with the dropped anchor or anchor wire. Conventionally, in such a case, an operator visually confirms an anchor buoy connected to an anchor of another work ship to confirm the anchor position of the other work ship, and avoids the anchor position to perform his own work. I was trying to throw a ship. However, such visual confirmation has a problem that it is difficult to accurately grasp the throwing position, and the safety at the time of throwing cannot be sufficiently secured.

In the anchorage monitoring system that detects the risk of running, it is proposed that the anchoring position information is acquired by a GPS receiver (see Patent Document 1). This system was proposed by focusing on one working ship anchored without assuming that there is another working ship around it. It was not considered to know the position of the work boat. In a work area where a plurality of work ships work, these work ships, cranes installed on the work ships, and the like become obstacles for communication. For this reason, if it is attempted to grasp the throwing position by simply communicating the position data using the wireless LAN, the position data indicating the throwing position may not be able to communicate due to a communication failure, and it is difficult to check the throwing position stably. There was a problem of becoming.
