- 海底ケーブルを探知するケーブル探知手段を所定の長さのロープを介して船舶と連結し、前記船舶の移動により前記ケーブル探知手段を海底に沿って移動させて前記海底ケーブルを探査する海底ケーブル探査方法であって、
前記ケーブル探知手段が前記海底ケーブルを横断するように前記船舶を移動させ前記ケーブル探知手段による前記海底ケーブルの探知時における前記船舶の往路位置をGPSを用いて記憶する往路探査工程と、
前記ケーブル探知手段が前記海底ケーブルを前記往路探査工程に対して反対方向から横断するように前記船舶を移動させ前記ケーブル探知手段による前記海底ケーブルの探知時における前記船舶の復路位置をGPSを用いて記憶する復路探査工程と、
前記GPSを用いて記憶された前記海底ケーブルの探知時における前記船舶の往路位置と復路位置との中間点を前記海底ケーブルの敷設位置と算出するケーブル位置算出工程と、
を有することを特徴とする海底ケーブル探査方法。 - 前記ケーブル探知手段による前記海底ケーブルの探知時における前記ロープの海面に対する入水角度を測定し、該入水角度を前記ケーブル位置算出工程における補正係数として用いることを特徴とする請求項1に記載の海底ケーブル探査方法。
