| description | To provide an inspection technique for an underwater cable with which no inspection portion is lost when a device is swept away by a tidal wave and an inspection position can be specified.SOLUTION: An inspection device 10 includes: an unmanned submarine vehicle 15; a clamp meter 11 that clamps to an underwater cable 31 to acquire a current flowing in the underwater cable 31 as a detection waveform; an arithmetic unit for calculating a phase difference between the detected waveform of the clamp meter 11 and a reference waveform; and a position specifying unit 48 for specifying an inspection position in the underwater cable 31 based on the phase difference.SELECTED DRAWING: Figure 2
【課題】装置が潮流に流されて点検箇所を見失うことがなく、さらに点検位置の特定が可能な、水中ケーブルの点検技術を提供する。【解決手段】点検装置１０は、無人潜水機１５と、水中ケーブル３１にクランプしこの水中ケーブル３１に流れる電流を検出波形として取得するクランプメータ１１と、クランプメータ１１の検出波形と基準波形との位相差を演算する演算部と、この位相差に基づいて水中ケーブル３１における点検位置を特定する位置特定部４８と、を備えている。【選択図】図２ |
