Proposal for modification of vulnerability criterion for surf-riding (broaching) stability failure suggested by IMO

Abstract

The paper covers vulnerability criterion for stability failure due to broaching during surf-riding suggested by IMO, while also outlining the key factors of the broaching taking into account the research of D.M. Ananyev. It has been demonstrated that a series of computational procedures of vulnerability assessment algorithm does not correspond to essence of the problem formulation and may be excluded. In addition, the Froude number range, at which capturing of the vessel by the following wave realizes, has been specified. The condition of surf-riding on the following wave has been corrected based on the assumption that value frequency of propeller rotation is known. The formulae for calculation of Froude — Krylov forces in the criterion has also been proposed. The correctness of the changes made has been verified by calculating of the vulnerability criterion for six different vessels.
