To provide a submarine structure detection device, a submarine structure detection system, and a submarine structure detection method capable of detecting a position of a structure provided on a seabed even when the magnitude of magnetism emitted from the structure provided on the seabed is small due to material quality of the structure provided on the seabed.SOLUTION: Disclosed is a submarine structure detection device 100 which detects a structure 1 provided on a seabed 14. This detection device includes: a plurality of supply electrode pairs 2 each having a positive electrode 2a and a negative electrode 2b; a plurality of potential difference detection parts 3 which are arranged between the positive electrode 2a and the negative electrode 2b and detect a potential difference between the positive electrode 2a and the negative electrode 2b due to the supplied current; and a control part 4 which controls determination of a position of a pipeline 1a based on change caused by the pipeline 1a of a detection signal 11 detected by the plurality of potential difference detection parts 3.SELECTED DRAWING: Figure 1

    【課題】海底に設けられた構造物の材質に起因して、海底に設けられた構造物から発せられる磁気の大きさが小さい場合でも、海底に設けられた構造物の位置を検出することが可能な海底構造物検出装置、海底構造物検出システム、および海底構造物検出方法を提供する。【解決手段】この海底構造物検出装置100は、海底14に設けられた構造物1を検出する海底構造物検出装置であって、各々が正極2aと負極2bとを有する複数の供給電極対2と、正極2aと負極2bとの間に配置され、供給された電流による正極2aと負極2bとの間の電位差を検出する複数の電位差検出部3と、複数の電位差検出部3によって検出された検出信号11のパイプライン1aに起因して生じる変化に基づいてパイプライン1aの位置を判定する制御を行う制御部4とを備える。【選択図】図1
