The Finnish Transport Agency makes decisions concerning the assistance period for winter navigation, exemptions and traffic restrictions. The objective is to cost-effectively guarantee that Finnish merchant shipping runs safely and smoothly in ice conditions.
When the ice situation becomes more difficult, the Finnish Transport Agency imposes traffic restrictions for the winter ports. Icebreaker assistance is given to vessels which meet the traffic restrictions issued by the Finnish Transport Agency for vessels calling at the relevant port.
The restrictions enter into force five days after their date of issue, except for relaxations, which enter into force at the date of issue.
