METHOD FOR GUIDING OBJECT TO TARGET POSITION UNDERWATER
PROBLEM TO BE SOLVED: To provide means for guiding an underwater object to a target position with high accuracy.SOLUTION: A method for guiding an underwater object to a target position comprises the steps of: guiding an installation object 21 to the vicinity immediately above an installation target position C by using the position of the installation object 21 specified on the basis of the position of a suspension point of the installation object 21 (a guiding mode); guiding the installation object 21 to the vicinity of the installation target position C by using the position of the installation object 21 specified with ultrasonic distance measurement between a transducer 15 disposed in a floating crane 11 and a transponder 22 disposed in the installation object 21 (a detail mode); and installing the installation object 21 to the installation target position C by using the position of the installation object 21 specified with ultrasonic distance measurement between the transponder 22 disposed in the installation object 21 and each of transponders 19-1, 19-2 disposed in an existing structure 18 (a proximity mode).
【課題】水中の対象物を高い精度で目標位置に誘導するための手段を提供する。【解決手段】据付対象物21の吊り下げ点の位置に基づき特定される据付対象物21の位置を用いて据付対象物21据付目標位置Cの直上付近に誘導し(誘導モード)、その後、起重機船11に配置された送受波器15と据付対象物21に配置されたトランスポンダ22との間の超音波測距により特定される据付対象物21の位置を用いて据付対象物21を据付目標位置Cの近辺まで誘導し(詳細モード)、その後、据付対象物21に配置されたトランスポンダ22と既設構造物18に配置されたトランスポンダ19−1および19−2の各々との間の超音波測距により特定される据付対象物21の位置を用いて据付対象物21を据付目標位置Cに据え付ける(近接モード)。【選択図】図1
