METHOD OF DETERMINING CONTACT OF STRUCTURE WITH WATER BOTTOM, AND WATER BOTTOM CONTACT DETERMINATION SYSTEM
PROBLEM TO BE SOLVED: To provide method of determining contact of structure with water bottom, and water bottom contact determination system capable of accurately determining a grounding state between a structure and the water bottom when installing the structure on the water bottom.SOLUTION: When installing a structure 4 lifted in water by lowering the same onto the water bottom B, a wobble sensor 2 is attached to the structure 4 to sequentially detect wobble data of the structure 4 with the wobble sensor 2. The wobble data detected by the wobble sensor 2 is sequentially input to a calculation unit. The calculation unit 3 carries out a series of data processing to correct disturbance data in the wobble data to obtain a piece of processed data. The calculation unit 3 determines the grounding state of the structure 4 onto the water bottom B based on a comparison between the processed data and a preset threshold level.SELECTED DRAWING: Figure 1
【課題】構造物を水底に据え付けるときに構造物の水底に対する着底具合を精度よく判断することができる構造物の水底着底判断方法および水底着底判断システムを提供する。【解決手段】水中に吊り下げた構造物４を下方移動させて水底Ｂに据え付ける際に、構造物４に動揺センサ２を設置し、動揺センサ２によって構造物４の動揺データを逐次検知する。そして、動揺センサ２が検知した動揺データを逐次演算装置に入力し、演算装置３によって動揺データに対して撹乱データを是正するデータ処理を行うことにより処理後データを取得する。この処理後データと予め設定している閾値との比較に基づいて、演算装置３により構造物４の水底Ｂに対する着底具合を判断する。【選択図】図１
