Ship Design with the Human Factor: Evacuation and normal operations modelling in
the ship design process
This thesis addresses the modelling of human factors and how they can impact
ship design. Two different but related applications areas are considered;
passenger ship evacuation analysis and naval vessel normal operations and
In the first instance, this thesis investigates the impact of
the current regulatory specified passenger response time distributions
upon evacuation analysis and then recommends a more realistic passenger
response time distribution which should be implemented when performing
an evacuation analysis of a passenger RO-RO vessel. This realistic
passenger response time distribution is based upon the results of sea
trials. The results of this analysis have been adopted by the IMO and
form part of the new guideline document, IMO MSC 1238.
In addition, this thesis addresses the analysis of the human factorsí
performance of a naval vessel. Naval vessels are built primarily for
undertaking assigned missions in times of war and conflict. While the
safety of those on board is important, the ability of the vessel to
function and complete its assigned mission is of paramount importance.
This thesis utilises an evacuation model, maritimeEXODUS, which was
extended to incorporate the functionality of modelling non-evacuation
scenarios, to assess the human factorsí performance of a naval vessel
during both normal operations and evacuation scenarios.
This thesis develops a methodology for simultaneously assessing the
human factorsí performance of both a range of normal operation scenarios
and evacuation scenario on board a naval vessel. The methodology, called
the Human Performance Metric (HPM), is discriminating, diagnostic,
systematic, transparent and reproducible in nature.
This thesis then implements the HPM methodology into the early stages
of the design cycle for a new naval vessel. The thesis presents the
software modifications required to implement the methodology in to the
design cycle as well as presenting a demonstration of the new system.
