Finnish Transport Agency, Winter Navigation Department
Vessels bound for Finnish ports and requiring icebreaker assistance shall, well in advance of entering ice-covered waters, report to an icebreaker in accordance with instructions given in the daily ice report. In addition, vessels bound for Gulf of Bothnia ports in which traffic restrictions apply shall, when passing Svenska Björn, report their nationality, name, port of destination, ETA and speed to ICEINFO on VHF channel 84. This report can also be given directly by phone + 46 31 69 91 00. If required, due to the ice conditions, the position for reporting can be trasferred farther to the south.
Vessels in the Gulf of Finland of 300 GT or more are required to report to the GOFREP Traffic Centre.
A vessel stuck in ice must notify the icebreaker of its position without delay.
