Robert Brown, FSEG PhD student (member of staff at Memorial University Canada) has been awarded the SFPE Foundation first annual Dr. Guylène Proulx, OC Scholarship. This award was established in 2014 in honour of Dr. Guylène Proulx, an outstanding researcher in human factors and human behaviour related to fire, and a passionate advocate for fire safety awareness. The grant will go towards funding Mr. Brown’s PhD project entitled “Collection, Analysis and Implementation of Human Performance Data from Planned Assembly Trials on Passenger Ships at Sea.” Rob’s PhD is based on work FSEG undertook as part of the EU FP7 SAFEGUARD project.

Robert Brown, Prof Ed Galea, Dr Steven Deere and Mr Lazaros Filippidis from FSEG have won the 2014 Medal of Distinction from the Royal Institution of Naval Architects (RINA). The award is made for the best paper to appear in the The Transactions of the Royal Institution of Naval Architects, International Journal of Maritime Engineering in 2013. The paper was entitled:

"Passenger Response Time Data-Sets for Large Passenger Ferries and Cruise Ships Derived from Sea Trials"

The paper was published in the RINA Journal, The Transactions of the Royal Institution of Naval Architects, International Journal of Maritime Engineering, Vol 155, Part A2, pp A97-A103, April-June 2013.

[29/08/2018] maritimeEXODUS v5.2 IS NOW AVAILABLE!

• New Functionality Features (Levels A, B and C)
  • Saving geometry boundaries as CAD DXF files.
    maritimeEXODUS now has the ability to save the boundaries of specific decks as CAD DXF files. Each deck can be saved in a format which enables it to be imported into third party software (i.e. CFD fire modelling software, 3D visualisation software etc.).
  • Enhanced Abandonment Phase Capabilities
    maritimeEXODUS has new options making the movement of agents between the AS and the LSAs more flexible. These new capabilities and options include; defining when the abandonment phase starts e.g. once the overall assembly is completed or when the assembly process is partially completed, etc., and how the agents are sent to the LSAs e.g. in groups of specified sizes, once a percentage of the previous group has boarded the LSA, etc.

• User interface (Levels A, B and C):
  • Updated Data Output Options Dialogue Box
    The format of the Data Output Options dialogue box has been updated and simplified. The output data attributes have been grouped and separated onto different tabs. Additional attributes have been included in the output list.

• Hazard Model (Level C Only)
  • There are a number of improvements to the Hazard model:
    
  • Updated HCN Model
    The toxicity model defining the effect of HCN on agents within EXODUS has been updated in order to ensure compatibility with the most recent version presented in the SFPE Handbook, 5th Edition.
    
  • Updated Default VCO2*RMV Cap
    The cap on VCO2*RMV has been decreased to 70 lit/min.
    
  • Updated the Default PID Distribution (FICO equation)
    There are three options available for setting the PID:
    • SFPE PID (Distribution) – Default Option:
      PID assigned from the distribution defined within the SFPE Handbook (5th Edition) – values between 5% and 45%.
    • Fixed Value PID:
      Each member of the population is assigned the same single value for PID. The default value is 30% COHb,
    • User Defined PID:
      PID determined by the user. This requires the user to populate a distribution table similar to that in option 1.
      
  • New Irritant Model Parameter, Tolerance Factor (TF)
    The TF attribute is a measure of the concentration of irritant gas (ppm) required to cause a given endpoint and is used in the FIC model. A TF is specified for each irritant agent considered in the model e.g. TFHCL.
    
  • Updated Agent Irritant Tolerance Concentration Model (FIC)
    End points of escape impairment and incapacitation due to irritant concentrations can now be specified. The lower threshold of escape impairment being the new default setting. Furthermore, there are now five methods for assigning the TF, with the endpoints being either Escape Impairment or Incapacitation.
    • SFPE Escape Impaired (Distribution) – Default Option:
      TF randomly assigned for each irritant gas from an assumed distribution based on data defined in the SFPE Handbook for Escape Impairment.
    • SFPE Escape Impaired (Fixed):
      A fixed TF for each irritant gas corresponding to the SFPE Escape Impaired mean values is assigned, the same value is used for each member of the population.
    • SFPE Incapacitation (Fixed):
      A fixed TF for each irritant gas corresponding to the SFPE Incapacitation mean values is assigned, the same value is used for each member of the population.
    • ISO 13571 Incapacitation (Fixed):
      A fixed TF for each irritant gas corresponding to the ISO 13571 Incapacitation mean values is assigned, the same value is sued for each member of the population.
    • User Defined:
      A user specified TF is used for each irritant. This can either be a fixed value, a range or a distribution.
      
  • New Irritant Model Parameter, Critical Irritant Incapacitation Factor (CIIF)
    The CIIF is a new parameter introduced due to the introduction of the new FIC option of Escape Impairment. The CIIF attribute defines the FIC value required to cause incapacitation. When the Escape Impairment option is used CIIF = 4.5.
    
  • New Irritant Model Parameter, Critical Dose (CD)
    The CD attribute is a measure of the dose of irritant gas (ppm.min) required to cause a given endpoint and is used in the FLD model. The endpoint is considered to be fatality, but there are three different CD values that can be used depending on the FLD model used. A CD value is required for each irritant agent considered e.g. CDHCL.
    
  • Updated Agent Irritant Tolerance Dose Model (FLD)
    In the new version of maritimeEXODUS FLD has no impact on an agent’s ability to evacuate but can be used to assess the likelihood of the exposed agent surviving post evacuation. In the new release there are three options for assigning the CDx values.
    • SFPE FLD Critical Dose – Default Option:
      CD for each irritant gas is specified as in the SFPE Handbook, the same value is used for each member of the population. This is based on mean values that are likely to cause fatality in 50% of the population.
    • AEGL-3 FLD Critical Dose:
      CD for each irritant gas is specified from the AEGL-3 distribution specified in the SFPE Handbook, the same value is used for each member of the population.
    • User Defined FLD Critical Dose:
      A user specified CD is used for each irritant.
      
  • New Heat Model Parameter, Radiant Heat Threshold (RHT)
    RHT (KW/m²) is a user defined parameter below which the FIHr is not calculated. The default value is 1.7 KW/m².

• Revisions to User Manual
  • Update to the Manual
    The user manual has been altered to reflect the changes specified above.
    
  • New Benchmark Case
    The user manual has been updated to include and demonstrate compliance with the additional benchmarking test case in the latest IMO regulatory guidelines (IMO MSC CIRC. 1533).
    

• New Functionality Features (Levels A, B and C)
  • Saving geometry boundaries as CAD DXF files.
    buildingEXODUS now has the ability to save the boundaries of specific floors as CAD DXF files. Each floor can be saved in a format which enables it to be imported into third party software (i.e. CFD fire modelling software, 3D visualisation software etc.).

• Multiple-Particle-Size smoke model:New model to represent smoke as a number of independent SOOT phases – each with different particle diameters and relative proportions – allowing smoke to experience gravitational settling, which can be an important smoke transport process in large scale geometries, such as tunnels.
  
• Algebraic Multi-Grid solver for pressure correction: This new solver assists the solution propagation in scenarios with highly refined meshes or in difficult geometries (e.g. tunnels). Unlike traditional Multi-Grid solvers, the algebraic form does not require separately generated real meshes.
  
• Enhanced Fractional Effective Dose (FED) monitor points with occupant characteristics:FED monitoring now allows each probe to be characterised with occupant characteristics to give a more accurate and representative understanding of the cumulative toxicity effect of the evolving solution.
