Technical safety

HVAC, gas dispersion, fire, smoke, radiation and blast & structural response analysis is delivered throughout the technical safety process by application of engineering know-how combined with CAE (computer aided engineering) technologies like CFD (computational fluid dynamics) and FEA (finite element analysis).

From front-end and concept engineering to ongoing operations, Prospect's technical safety activity is focused on assisting clients in effective risk management through use of its core services, which include:

• Flow related and thermal engineering
