Development of safe means for people rescue on ships in case of fire has been a concern for scientists and workers of the marine field for a long time. This is especially true for cargo and industrial shipping. Use of a floating rescue capsule to rescue people, who appear aboard a ship in fire is one of the possible solutions of this problem. Today, there are no effective, cheap fire prevention means for the collective protection of people on the water. The available devices are quite cumbersome and expensive because of the materials they are made. Therefore, the ship-owners often neglect the safety of people, not providing the ships with reliable means of people rescuing on the water. It uses the tools that are as affordable as possible and not too reliable and are used only formally.
For safe and effective use of such a capsule, a number of requirements must be met. In other case, use of such remedy is not relevant. The basic requirements that must be solved include buoyancy, fire resistance, water resistance, shape, durability and reliability, comfort, production manufacturability, efficiency. One of the important factors that generally influences the execution of all requirements is the material of which this rescue capsule is made.
To construct such device, it is proposed to use the materials, which are widely used in building, but almost not used in shipbuilding, i.e. foam concrete that is a kind of nondrobate concrete. Foam concrete satisfies almost all requirements, set to such rescue capsules. It is a fairly light material, having high flotation, and the most importantly – high fire resistance. The technology of its production is simple, and economical. Taking certain measures and operations, one can improve the strength of this material up to the required level, and by treating the surface of the foam concrete with certain modern blends or solutions, it is possible to achieve almost one hundred percent water resistance.
