Dislocation of Objects on a Ship as a Method of Fire Protection

Krystosik-Gromadzinska A.

Archivum Combustionis

Vol. 30 nr 4

The paper describes problems of fire protection on a ship. The main idea is a presentation of alternative design method of fire protection on the ship- dislocation of objects. Some examples are described. The algorithm for quantity verification of dislocation, and some calculations are presented too. Fires at sea are potentially the most hazardous and costly in terms of human life. The fire protection of the ship is connected with active and passive methods. This paper mainly focuses on passive methods of fire protection. The main idea of it is a presentation of dislocation of risk objects as an alternative method of fire protection, which aim is to stop fire spread between risk objects like an engine room and accommodation spaces but also other ones. The dislocation can apply with a significant benefit to almost all types of ships. The algorithm, helpful in analysis of risk objects interplay during fire spread and indication of the safety distance between them, is described in this paper too. The algorithm describes dependencies between the place of fire origin, time of spread between risk objects, material used to produce object e.g. bulkhead and the distance between them. The algorithm, which finds optimal distance between objects, comply influence of fire parameters, heat transfer parameters but also the thickness of insulation which prescribe costs.
