Model-based investigations on dynamic ship heels in relation to maritime transport safety

The paper has been presented criteria of similarity between of liquid motion. Results of initial research on air flow’s dynamic impact on a ship model of 888 project type are presented in the elaboration as well. The research has been executed at a test stand located in the Polish Naval Academy. The ship model of 888 project type has been an object of the tests. Results of executed measurements have been compared with theoretical calculations for an angle of dynamic heel. Input parameters for the tests and calculations have been defined in accordance with recommendations of Polish Register of Shipping (PRS) and IMO (IMO Instruments). Determination of a heeling moment by wind operation has been a key issue.
