Comparative Analysis of the Dynamic Angle of Heel of a Shipe 888 Project Type Defined of the Calculation and Model Tests

Abstract

Results of initial research on air flow’s dynamic impact on a ship model of 888 project type are presented in the elaboration. 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 1993, 2008, PRS 2007). Determination of a heeling moment by wind operation has been a key issue. The executed research has revealed that the way the criteria of the ship’s dynamic stability are defined by PRS and IMO takes a certain safety margin into account.
