Guidelines for an Advanced Evacuation Analysis of New and Existing Passenger Shipsfootnote

1 Specific assumptions

This method of estimating the evacuation duration is based on several idealized benchmark scenarios and the following assumptions are made:

  • .1 the passengers and crew are represented as unique individuals with specified individual abilities and response durations;

  • .2 a safety factor having a value of 1.25 is introduced in the calculation to take account of model omissions, assumptions, and the limited number and nature of the benchmark scenarios considered.

2 Calculation of the evacuation duration

The following components should be included in the calculation of the evacuation duration as specified in the appendix:

  • .1 the response duration (R) distribution to be used in the calculations;

  • .2 the method to determine the travel duration (T); and

  • .3 embarkation and launching duration (E+L).

3 Identification of congestion

3.1 Congestion within regions is identified by local population densities exceeding 4 p/m2 for significant duration. These levels of congestion may or may not be significant to the overall assembly process.

3.2 If any identified congestion region is found to persist for longer than 10% of the simulated total assembly duration (tA), it is considered to be significant.
