Winter navigation

The Finnish Transport Agency is tasked with public office duties and the procurement associated with the assistance of winter navigation as well with the national coordination, development and guidance thereof.

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.


Traffic restrictions

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.

Preliminary information on traffic restrictions: Weeks 22 and 23 (21.5.2018). Icebreaking season has ended.

The Finnish Transport Agency has updated its publication Finland's Winter Navigation 2017–2018.

This icebreaking season, all vessels arriving for the first time of the winter season to a Finnish or Swedish assistance area will be asked, in English, whether they accept and agree to follow the general instructions for icebreaking issued by the national maritime authorities.

The vessel or shipping company is advised to give its reply before the vessel arrives to the assistance area by e-mail to Turku Radio ( answer will affect the assistance of the vessel.

Brokers are asked to ensure that the publication Finland’s Winter Navigation 2017–2018 has been delivered to all vessels/shipping companies before the vessels arrive to the assistance area. Shipping companies should take the instructions into account already when drawing up charter parties.

The guide is mainly intended for deck officers and it is a maritime publication compliant with SOLAS regulations and with the provisions relating to route planning and the safe passage of the vessel under the Maritime Act. It also includes information and instructions about the special conditions in the Baltic Sea, as well as useful information for charterers and all parties working towards smooth and particularly safe winter navigation.

In order to ensure a safe and smooth flow of traffic in the entire winter navigation system, it is vital that your vessel meets the requirements and that the crew follows the instructions in Finland's Winter Navigation 2017–2018.

Winter navigation is teamwork.
