Action to neutralise a naval mine near Gdynia continues

This morning, Tuesday 16 June, at 8 a.m., an operation to neutralise a World War II naval mine began in Gdynia. During the whole operation sailing restrictions were introduced, as well as a ban on bathing and some streets were closed. The whole operation is scheduled to end at 15.00.

A dangerous find, a remnant of the turbulent history of the region, was discovered between the southern entrance to the Port of Gdynia and the Basen Żeglarski. The relevant services were immediately notified, and they began planning the neutralisation of the object and the danger it posed.

As always in such cases, the best experts in the field, the Group of Miner Divers, as well as the crews of ORP Kormoran and ORP Flaming from the 13th minesweeper division of the 8th Coastal Defence Flotilla, went into action. At present, we know that operations are proceeding according to plan. The mine has been picked up and is now being towed into the waters of the Gulf of Gdansk, where it will be neutralised.

The most probable date of the operation is 16.06.this year. – The final confirmation will take place on Monday, 15.06.this year.

For the duration of the works related to the precise operation of lifting the object above the bottom and towing it to the designated neutralisation area, specific safety zones and restrictions on navigation and an absolute ban on bathing (entering the water) will be in force.

Taking into account the explosive power of the mine, a safety zone with a radius of 10750 m from the point of destruction was defined, which includes the coastline in the section Rewa – Gdańsk Westerplatte (inclusive) and other safety zones as shown on the map below.
