Reduce the impact of possible CBRN contamination on service personnel and the operation of CVF
Frazer-Nash has been a long term partner in the CVF project and were involved in design activities, structural and airwake analysis.
The new Royal Navy Queen Elizabeth Class Aircraft Carrier needed a comprehensive Chemical, Biological, Radiological and Nuclear (CBRN) defence capability to reduce the impact of contamination on personnel and operation of the ship. The proposals had to balance the cost-benefit of the CBRN systems and fully comply with the MoD Defence Standards.
- We used a risk-based analysis of the likelihood and severity of contamination, based upon a number of scenarios, to identify areas of the ship under the greatest stress.
- We then compared these aspects against the MoD Defence Standards to provide solutions that addressed both the risk and Defence Standard requirements.
- We then used airflow analysis to establish where the chemical, radiation and biological detectors should be placed, and how many would be needed.
- We also used mathematical modelling to determine whether or not a nuclear command shelter station was necessary.
- We then designed the cleansing stations so that personnel entering the ship from contaminated areas could be quickly decontaminated before accessing the citadel.
Working within a framework of complicated technical constraints and financial budget, Frazer-Nash were able to integrate the needs of the end-user, whilst also achieving the CBRN design goals within the larger context of the ship.
