Floating ice of 10-15 cm thick and concentration of 9/10ths to 10/10ths is observed between the entrance buoy and the Dock-Gate Building C-1; floating ice of up to 05 cm thick and concentration of 7/10ths to 8/10ths is observed between the Dock-Gate Building C-1 and buoys No 27, No 28. Between buoys No 27, No 28 and closed part of St. Petersburg Seaway Channel ice concentration is 10/10ths, ice thickness is 15-20 cm, ice compacting is observed. In the water area of Big Port St. Petersburg: brash ice of 10-15 cm thick and concentration of 9/10ths to 10/10ths. Between the port of Vyborg and Vysotsk: consolidated ice of 10-15 cm thick. Southwards of port Vysotsk to the Rondo island: 5-15 cm tick ice. At port Primorsk: ice thickness of up to 20 cm, ice concentration of 10/10ths.
At the port of Primorsk and at the approaches to it, navigation of ATB units and non-ice class ships is banned from 26 January 2018. Ice1 class ships will be only allowed to sail in ice waters with the assistance of icebreakers, ships of Ice 2 class and higher ice classes will be allowed to sail independently upon obtaining icebreaker’s permit and recommendations, or assistance.
