Automated Method for Navigation Bridge Visibility Regulation Review in Ship Design

This study presents a system for automatically reviewing navigation bridge visibility regulations using 3D ship models. Traditional manual review methods based on 2D drawings rely heavily on the designer's experience, resulting in low accuracy and time inefficiency. To address these issues, this research proposes a method that uses 3D ship models and visualization models to identify and analyze obstructions to navigation bridge operators' visibility. By performing interference checks, the system can automatically calculate and evaluate blind sectors. The proposed system applies specific regulations for each obstruction and determines compliance based on the calculated blind sector size. The system was applied to a membrane type LNG tanker and the results were comparable to those obtained by conventional 2D drawing based inspections.
