Enabling ship survivability
InterDam engineers and manufactures specialized products aimed at maximizing ship survivability whilst minimizing weight. These doors are a crucial element for customers who implement the principles of Resilient Ship Design. The doors are designed to withstand the major effects of weapons damage that a naval ship can encounter, including ASM strikes and mine strikes. InterDam manufactures Level I and Level II blast doors that are tested and certified to withstand blast, shock and fire loads at a significantly lower weight than competing products. Unique for a door with its capabilities, our Nadam 4 Level II door is manually operated with a single handle. Through our R&D and manufacturing experience, and in collaboration with our knowledge partners, we can also provide customized versions of these high-blast doors, for example to provide access for vehicles, or customized opening systems.
