Abstract: Abstract： In order to assure the safety of ships sailing in the storm, the International Maritime Organization (IMO) has developed vulnerability criteria to assess whether the surfriding/broaching occurred to a ship or not. The proposal of vulnerability criteria to the second layer of surfriding/broaching by Japanese scholars in the conference of IMO SLF55/INF.15 was analyzed to compile a calculating program by using Maple, a mathematical tool. Taking a container ship, an oil tanker and a fishery ship as examples, the vulnerability criteria was calculated, and the probability of occurrence of surfriding broaching was determined. The results were used to verify the applicability and versatility of this program, which laid a foundation for the revision of the second generation intact stability criteria.

Key words: surfriding/broaching, vulnerability criteria, second generation intact stability criteria
