Description

  The present invention shows the situation that affects the mooring such as tension on the mooring line, wind direction and speed around the land side, tidal current direction and flow velocity, draft and displacement of the ship when mooring the ship on a pier or floating island. The present invention relates to a ship mooring monitoring device for monitoring and displaying, and mainly relates to a ship mooring monitoring terminal device that is used by being brought into a large tanker moored at a petroleum product such as crude oil or an LNG receiving terminal. .

  When a large ship is moored on a pier or floating island, it is moored using many mooring lines having a predetermined strength, but a functioning mooring line changes from moment to moment depending on wind, tides, and other conditions. In the case of a large ship passing nearby or under bad weather conditions, the influence of the load caused by the swell of the sea surface, wind, and waves on the ship may concentrate on just a few mooring lines, limiting the ship to the limit. If it is shaken excessively, it may cause damage to the loading arm and mooring line, and in the worst case, it may lead to accidents of ships and workers.

  Therefore, a mooring load monitoring device (MLM) is installed on the land side 1 such as a pier where a large ship S is moored, particularly on the land side 1 handling petroleum products such as crude oil and LNG. Conventionally, for example, as shown in FIG. 4, detection data from various sensors is guided and processed by the land-side terminal device 12 installed in the central monitoring room 11 on the land-side 1 via the input / output device 35. Is always displayed on the display 13 as mooring information, and an alarm is issued if necessary.

  A communication cable 15 for mutual communication and alarm is laid between the central management room 11 on the land side 1 and the bridge 14 of the ship S. In the case of the land side 1 and the ship S that handle petroleum products and LNG, the communication cable 15 uses an optical fiber line instead of a metal line for explosion prevention, and an optical fiber line is used between the land side 1 and the ship S. The connector 36 contacts and separates. Optical transmission devices 37 and 38 are provided at both ends of the optical fiber communication cable 15 and telephone and alarm devices 39 and 40 are connected thereto.

  Further, the optical transmission device 37 is connected to the input / output device 35 on the central monitoring room 11 side via a modem 41. Further, the ship-side terminal device 16 is connected to the optical transmission device 38 on the bridge 14 side via the modem 42 only when the ship-side terminal device 16 having the same specifications as the land-side terminal device 12 is mounted on the ship S side. The detection data from various sensors is also transmitted from the input / output device 35 to the ship-side terminal device 16 via the optical fiber communication cable 15, and the mooring information necessary on the ship S side among those displayed on the display 13. Is also displayed on the display 43.

  Patent Document 1 is disclosed as a mooring load monitoring device for detecting the tension of the mooring line 5. As shown in FIG. 3, the mooring load monitoring device disclosed in Patent Document 1 is connected to a floating island (mooring dolphin) 44 by a plurality of mooring lines (mooring ropes) 5 that are connected via a fender 4. In the ship S moored at the pier (moorage facility) 2, the respective tensions applied to the plurality of mooring lines 5 are detected by the tension detectors 18 provided at the plurality of floating islands 44 and the pier 2, Based on this, the mooring state of the ship S can be monitored.
