Embodiment 1

[0102] Such as image 3 Shown is a schematic diagram of partial evacuation of an offshore building.

[0103] Fire detection and alarm time T A : Fire growth coefficient, take 0.1878(k W·s -2 ). Then the alarm time of the detector can be calculated as:

[0104] According to the relevant regulations in (GB4717-93): when the fire alarm controller performs operations such as query, judgment and data processing, the fire alarm signal reception delay should be within 10s; then T A ≤40s.

[0105] Evacuation time t in the fire room start,rm :

[0106] Option 1: If there is a fire in the room, only the analysis of N 1 The evacuation time of the people in the middle, that is, A area for N 1 The area of ​​the room S 1 :

[0107]

[0108] Scheme 2: The fire location is located at N 1 , N 2 , N 3 , N 4 The midpoint of the room, it is necessary to analyze the evacuation time of the people in the four rooms, that is, A area for N 1 , N 2 , N 3 , N 4 The area of ​​the...

Abstract

The invention provides a method for calculating emergency escape evacuation time of offshore personnel in a fire disaster. The method comprehensively considers the detection time of a detector under afire condition, the reaction time of personnel after receiving a fire signal, the evacuation time in a fire scene and the total evacuation travel time, and has important theoretical value and socialsignificance for ship design, emergency situation setting, evacuation plan making and even promotion of the improvement of the safety of the shipping industry.

Description

technical field [0001] The invention belongs to the field of assessing the evacuation ability of ship personnel, and in particular relates to a calculation method for emergency escape and evacuation time of sea personnel in case of fire. Background technique [0002] With the continuous development of shipbuilding technology, the design and construction of ships presents a trend of large-scale, complex and intelligent development. The load capacity and passenger capacity of ships continue to increase. Once disasters such as capsizing and fire occur, even greater Loss of life and property. Therefore, how to realize the orderly and rapid evacuation of a large number of people in the complex and narrow space of the hull has become a key issue in ship design, that is, to evaluate the evacuation ability of ship personnel in the early stage of design, and for ship design, emergency scenario setting, evacuation, etc. The formulation of the plan and even the improvement of the safe...
