The securing scheme of shipborne vehicles is made in view of small cars and heavy duty trucks, the principle of securing check with accurate calculation method is introduced, and the vehicle securing safety check system for 98 m Ro-Ro passenger HSC is developed based on this securing scheme and securing check method. This system can be used to check the feasibility and safety of securing scheme. For the securing points that do not meet the safety requirements, the relevant parameters can be modified, and the calculation and verification can be carried out again until the securing scheme that meets the safety requirements is obtained, which can significantly improve the check and improvement efficiency of securing scheme.
