In the 3rd quarter of 2021, dredging works to restore the design depths of the DSC were carried out in the sea approach channel in a total volume of 42,684.2m3. Storage of bottom sediments was carried out on a marine underwater dump. The works was carried out by the self-transport dredger "Ingulsky" in the period from July 1 to August 19, 2021 with technological breaks. The works was carried out outside the terms of specialized spawning bans for fishing in 2021. In the 4th quarter of 2021, bottom dredging operations were carried out on the sea water canal in total of 82068.0m3. The storage of the sediments was carried out on the sea underwater dump. The works was carried out by the self-transport dredger "Ingulsky" in the period from 01.10to31.12.2021 with technological breaks. The works was carried out outside the terms of specialized spawning bans for fishing in 2021. Dredging works were carried out according to the proposed technology, taking into account measures aimed at reducing the negative impact on aquatic biological resources. According to information from the "Delta Pilot" branch of the State Enterprise "AMPU", in 2022 it is planned to carry out dredging works on the sea part of the approach channel of the DSC with a total volume of 474,500.0m3, in order to implement project solutions to maintain the necessary navigable depths that are safe for navigation. Part of the work is planned to be carried out during the periods of the state ban on fishing with a total volume of 257,400.0m3 .
