International Code on Intact Stability 2008/Международный кодекс об остойчивости судов в неповрежденном состоянии 2008

Издание на английском языке
The International Code on Intact Stability, 2008 (2008 IS Code) sets out mandatory stability criteria and recommendations for the safe design and operation of ships. It covers stability calculations, loading conditions, free surface effects, icing, watertight integrity, and inclining tests, together with operational precautions against capsizing in heavy weather. Specific provisions address different ship types and operations, including towing, anchor handling, and lifting. The 2020 edition incorporates amendments to the Code and includes explanatory notes and unified interpretations that clarify its technical provisions and support their consistent application.
