What is the assumed ice weight carried on all horizontal surfaces as per Full Icing Allowances?

The assumed ice weight carried on all horizontal surfaces, according to Full Icing Allowances, is specified as 30 kg/m². This value is based on the principles of stability regarding the additional weight that ice can add to a vessel, which directly affects its stability and safety at sea.

When calculating for stability in icy conditions, it is critical to account for the potential weight of ice accumulation on deck and other horizontal surfaces. Using 30 kg/m² ensures a conservative approach to assess the impact of icing on the vessel's centroid, which influences metacentric height and overall stability.

This value is widely accepted in maritime regulations and standards to ensure the integrity and safety of vessels operating in cold environments, making it crucial for officers and sailors to utilize this figure in stability calculations and vessel design considerations.
