To provide a means capable of seating multiple legs of a self-elevating platform in a stable condition on a water bottom.SOLUTION: A three dimensional sonar 60 or a range finder 62 continuously measures at least one of each position of multiple legs 52 and the shape of the submarine ground while lowering the multiple legs 52 of a self-elevating platform 5 toward a water bottom 3. A display device 57 displays the measured results by the three dimensional sonar 60 or the range finder 62. Each of the multiple legs 52 is seated in the period of a prescribed time length. The three dimensional sonar 60 is provided on a bottom part of a hull 51 of the self-elevating platform 5. The range finder 62 is provided at each of the multiple legs 52 of the self-elevating platform 5.SELECTED DRAWING: Figure 1

    【課題】安定した状態で自己昇降式作業台船の複数の脚を水底に着座させることができる手段を提供する。【解決手段】自己昇降式作業台船5の複数の脚52を水底3に向かい降下させながら、複数の脚52の各々の位置及び水底地盤の形状の少なくとも一方を3次元ソナー60あるいは測距器62で継続的に計測する。3次元ソナー60あるいは測距器62での計測の結果は表示装置57に表示する。複数の脚52の各々を所定時間長の期間内に着座させる。3次元ソナー60は、自己昇降式作業台船5の船体51の底部に設けられる。測距器62は、自己昇降式作業台船5の複数の脚52の各々に設けられる。【選択図】図1
