摘要：
At a location where a submarine cable 20 is to be installed, the condition of a seabed 200 and the condition of tidal currents near the seabed 200 are investigated in advance to examine the number of filter units 50 and the position where the filter units 50 are to be installed. First, the submarine cable 20 is installed on the seabed 200. Then, the filter units 50 are installed so as to cover the submarine cable 20 installed on the seabed 200.
