Railotech Inspection, Survey & Testing
Ice model tests
Ice model testing in Railotech’s own ice basin in Helsinki, for its own designs and for other designers, shipyards and owners.
Description
Ice model testing verifies hull form and propulsion functionality before a ship is built. The first Finnish ice test basin was built in 1969; the present basin in Helsinki is the third operated by the company and its predecessors, and more than 700 ice model test programmes have been completed. Model ice is scaled to represent level ice, brash channels, rubble, ridges and floe ice, and underwater windows allow filming of the tests.
Test types
- Icebreaking performance and manoeuvring in ice
- Global ice loads on structures
- Mooring and dynamic positioning (DP) in ice
- Loading and offloading operations
- Ice encroachment on artificial islands
- Autonomous ship testing and multi-vessel operations
- Hull coating friction
