P & I Design have since its inception been involved in providing Safety Studies for the Process Industry. These include HAZID (Hazard identification) & HAZOP (Hazard & Operability) Studies.

Since the introduction of IEC 61508 and subsequent BSEN 61508 & BSEN 61511 we have been providing LOPA studies and SIL determination.

The use of LOPA as a risk assesment tool has developed significantly since the explosion at the Hereford Oil Storage Depot at Buncfield in December 2005.
