Study on the IMO Second Generation Intact Stability Criteria of Surf-riding/Broaching Failure Mode

摘要

A series of investigations on the vulnerability criteria for the surf-riding/broaching stability failure mode is conducted. First and foremost, free running model experiment of a purse seiner in severe following waves is performed to demonstrate the fatalness of surf-riding/broaching. The latest IMO proposal to assess broaching stability failure mode is then studied in detail. A numerical code with user interface is developed to facilitate sensitivity analyses and sample ship calculations. The appropriateness of the proposal is analyzed and its potential impact on ship design is discussed.
