The Finnish and Swedish maritime authorities have elaborated and issued Finnish-Swedish ice class regulations (or rules, FSICR) since 1971. The regulations have also been incorporated into the rules of the classification societies.
In Finnish law, provisions on ice classes are included in the Act on the Ice Classes of Ships and Icebreaker Assistance (1121/2005). The year of build of a ship determines which set of regulations apply to the ship. Provisions on the application of the various sets of regulations are laid down in the 2010 regulations.
The ice class regulations define the minimum engine output, hull strength, machinery and rudder strength of ships navigating in ice. The ice class affects the net tonnage of the ship, which in turn forms the basis for determining the size of the fairway due to be charged. When restrictions concerning icebreaker assistance are imposed, it depends on the ice class whether a ship is entitled to assistance or not.
The aim of the regulations is to ensure that ships operating in the Baltic Sea are capable of navigating in ice and winter navigation runs safely and smoothly.
Trafi has issued a regulation on which Finnish ice classes are equivalent to the class notations of recognized classification societies (the so called list of equivalences). If a ship has an ice class notation of a recognized classification society, it is granted one of the Finnish ice classes IA Super, IA, IB, IC, II and III in accordance with the equivalence list.
The regulation also includes provisions on documentation required for the determination of the ice classes of ships.
Keeping the ice class rules up to date as vessel structures constantly develop requires continuous research and development work. The Finnish Transport Safety Agency (Trafi), Finnish Transport Agency and the Swedish Maritime Administration (SMA) invite research institutes to apply for finance for research projects to be carried out in 2017 with an aim to facilitate winter navigation.
Detailed instructions for application are given in the attached documents. The applications shall be submitted to Trafi and to the SMA in accordance with the instructions by 15 September 2016 at the latest. Late applications will not be processed.
