In addition to CFD explosion modelling, we also have experience managing the following:
- CFD turbine exhaust plume modelling, normally with respect to Helideck impact
- CFD fire modelling, including thermal radiation contours and smoke/CO modelling
- Optimisation of gas detector layouts based on CFD ventilation modelling
Detailed CFD Modelling
There is often a need to perform detailed CFD modelling to compare layout options, examine the benefit of incorporating additional fire/blast walls, determine Design Accidental Loading (DALs), etc.
This work is performed in conjunction with a third party consultant such as Gexcon or MMI. ORC will perform an initial "high level" assessment to determine "areas of concern". ORC will then identify areas for further study and manage the process. It is very important to provide the relevant information to the TPC and assess the results so as to obtain meaningful outcomes.
ORC have been involved with many such studies including:
- Optimisation of equipment layouts/orientation
- Maximisation of natural ventilation and blast venting
- Impact of fire/blast wall layout and additional barriers
- Benefit of additional fire/blast barriers
- Optimisation of gaps between modules
- Plated versus grated decks
- Incorporation of blast relief panels
- Full probalistic explosion modelling to determine credible DALs (eg. based on acceptable retune period - typically 1 in 10,000 years)
- Determining the response of structures and equipment to short duration blast pulses using elasto-plastic techniques
