DNV Nauticus Hull 2025 v20.36

DNV Nauticus Hull 2025 v20.36

DNV Nauticus Hull is the industry-leading software for ship structural design and analysis, fully integrated with DNV’s classification rules and international regulations. It provides a complete workflow from initial 3D structural modeling to finite element analysis, fatigue assessment, and automatic generation of classification-approval documentation. The software is built on DNV’s extensive experience in marine classification and incorporates the latest rules (DNV, IACS Common Structural Rules) for tankers, bulk carriers, container ships, and offshore units.
