A Hazard and Operability (HAZOP) Review has recently been completed by EPConsult Energies as part of the TOTAL Lindsey Oil Refinery (LOR) Sulphur Degassing FEED project. The objective of the HAZOP study was to ensure the system is safe and to identify potentially hazardous deviations from the design intention as well as operability hazards and difficulties. Where necessary, actions were raised in order to reduce or eliminate identified hazards.
The HAZOP review was then followed by a Safety Integrity Level (SIL) review. The assessment was performed taking into account frequency of the demand, the extent of the injury to personnel, or damage to equipment, or environmental damage, probability of personnel presence and the possibility to avert hazard.
