Abstract
A submerged submarine is highly sensitive to fires since the fire residues cannot be directly ventilated to the atmosphere. Deadly outcome could be the result if the submarine does not reach the surface within time or manages to purify the air while submerged. Reasons for not reaching the surface could be enemies at the surface or system failure. No Swedish submarines are today able to purify fire residues. This thesis have identified and evaluated potentials products for doing this.
The most important fire residues to purify are the ones causing suffocation, e.g. low oxygen, carbon dioxide, carbon monoxide and hydrogen cyanide. Indirectly dangerous substances are the ones having an irritating effect and obstructing the ability to operate... (More)
A submerged submarine is highly sensitive to fires since the fire residues cannot be directly ventilated to the atmosphere. Deadly outcome could be the result if the submarine does not reach the surface within time or manages to purify the air while submerged. Reasons for not reaching the surface could be enemies at the surface or system failure. No Swedish submarines are today able to purify fire residues. This thesis have identified and evaluated potentials products for doing this.
The most important fire residues to purify are the ones causing suffocation, e.g. low oxygen, carbon dioxide, carbon monoxide and hydrogen cyanide. Indirectly dangerous substances are the ones having an irritating effect and obstructing the ability to operate and perform simple tasks. Examples of irritating fire residues are sulphur dioxide and nitrogen dioxide. The smallest particles are also dangerous since they can reach deep down into the lungs and affect the bloods capability to carry oxygen.
Seven purification techniques along with product examples are covered in this thesis. The evaluation against submarine requirements and prioritized residues shows that the best identified concept is based on not one, but four different techniques. The most promising combination of products involves using CASPA and MCASPA from Molecular Products together with ES-600 from Temet and the current ventilation systems. The techniques used in the concept needs to be tested in practice. It needs to be complemented with a solution to purify nitrogen dioxide since a product for removing this substance has not been found. The concept is not guaranteed to work since each fire is unique. It will however increase the chances of surviving. (Less)
