Offshore Oil and Gas Fire Analysis

ComputIT is carrying out fire simulation and analysis

  • for design purposes, i.e. module layout with respect to fire (fire walls, drains etc), layout in terms of process design, protection of equipment and structures by passive or active systems, escape route analysis and design, others
  • as third party controller for oil and gas companies
  • for accident investigation
  • as part of risk analysis
  • to demonstrate consequences of fires in general
  • others

 

Pool fires are simulated transient and 3D by KFX®. The pools may be predefined and fixed in size, or they may have a transient development caused by a transient leak, and pool formation and spreading is taken into account. The simulations include detailed combustion and transient radiation back to the evaporating pool, and smoke production and smoke dispersion is simultaneously simulated. Simulations are carried out in complex geometries or in enclosed space, and with external wind and/or natural or mechanical ventilation systems impacting the fire development. Radiation for instance to equipment and structures or in personnel areas are calculated.

Gas jet fires are simulated transient and 3D by KFX®. High-pressure leaks in complex environments are treated and the breaking up of jets hitting equipment and obstacles are simulated. As for pool fires combustion, smoke production and dispersion is simultaneously simulated. Simulations are carried out in complex geometries or in enclosed space, and with external wind and/or natural or mechanical ventilation systems impacting the fire development. Radiation for instance to equipment and structures or in personnel areas are calculated.

Two-phase spray fires are simulated transient and 3D by KFX®. This includes two phase leak sources where both gas an oil are released or where a one phase source will flash and form two phases when released to atmosphere. Two-phase sprays may burn as simultaneous gas and droplets combustion, and unburned droplets will form pools when hitting floors etc. Such pools will burn as pool fires. As for the other types of fires combustion, smoke production and dispersion is simultaneously simulated. Simulations are carried out in complex geometries or in enclosed space, and with external wind and/or natural or mechanical ventilation systems impacting the fire development. Radiation for instance to equipment and structures or in personnel areas are calculated.

The transient and non uniform heating of equipment and load carrying structures due to fires can also be simulated, including dynamic mechanical response, deformation and global collapse of structures. See Structural Fire Response Analysis
