Ice navigation limitations come into effect at Big Port St. Petersburg from January 20

Ice navigation limitations come into effect at Big Port St. Petersburg from January 20 provided that ice is 10-15 cm thick, says the port authority’s headquarters for icebreaking operations.

Tug and tow trains are prohibited from ice navigation. Vessels without ice reinforcement (non-ice-class vessels) are allowed for ice navigation only with icebreakers’ support. Vessels with category of Ice 1 and above are allowed for navigation in ice-covered waters either independently or with icebreaking escort.
