Structural Fire Response Analysis - Aker Kværner cooperates closely with ComputIT

The structural consequences of fires are very important to control, and ComputIT collaborates closely with Usfos AS and Aker Kværner ASA in this respect.

As part of such integrated fire analysis the need for and optimization of passive fire protection of structures can be simulated. It is our experience that such analyses are very cost efficient and often reduce cost, reduce weight, and improve maintenance efficiency.

ComputIT is collaborating closely with Usfos AS and Aker Kværner:

  • 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
  • for accident investigation
  • as part of risk analysis
  • to demonstrate consequences of fires in general 

The transient and non uniform heating of equipment and load carrying structures exposed to fires are simulated by the Finite Element code Fahts/Usfos. Usfos accurately simulates the collapse process, from the initial yielding, through to the formation of a complete collapse mechanism and the finale toppling of the structure.

The program has proved significant cost savings in areas such as inspection planning, lifetime extension / reassessment of ageing structures, and in fire protection assessment for new designs.

The KFX® integrated fire system includes an automatic link to the FE systems and makes this an efficient tool for integrated analysis.
