To monitor an extending direction of a mooring cable from a hull to a mooring post without using strain gauges.SOLUTION: A processing circuit of a mooring cable monitoring device according to one aspect is configured to acquire hardware coordinate information indicating a positional coordinate of a mooring hardware in a hull coordinate system that is the coordinate system relative to a hull, acquire first mooring post coordinate information indicating a positional coordinate of a mooring post in an absolute coordinate system, acquire hull coordinate information indicating a positional coordinate of the hull in the absolute coordinate system, acquire hull azimuth information indicating a hull direction in the absolute coordinate system, acquire second mooring post coordinate information by converting the positional coordinate indicated by the first mooring post coordinate information to the hull coordinate system from the absolute coordinate system based on the hull coordinate information and on the hull azimuth information, and calculate the horizontal angle that is an angle made by the extending direction of the mooring cable with respect to the hull direction seen from the vertical direction based on the second mooring post coordinate and the hardware coordinate information.SELECTED DRAWING: Figure 5

    【課題】歪ゲージを用いることなく、船体から係船柱へ係船索の延びる方向を監視する。【解決手段】一態様に係る係船索監視装置の処理回路は、船体を基準とする座標系である船体座標系における係船金物の位置座標を示す金物座標情報を取得し、絶対座標系における係船柱の位置座標を示す第1係船柱座標情報を取得し、絶対座標系における船体の位置座標を示す船体座標情報を取得し、絶対座標系における船体の向きを示す船体方位情報を取得し、船体座標情報および船体方位情報に基づいて、第1係船柱座標情報が示す位置座標を、絶対座標系から船体座標系に変換することにより第2係船柱座標情報を取得し、第2係船柱座標と金物座標情報とにより、鉛直方向に見たときの船体の向きに対して係船索の延在方向がなす角度である水平角度を算出するように構成されている。【選択図】図5
