Study Application

    LOPA can be applied through the entire project lifecycle from conceptual design to operation. However, it is advantageous for LOPA to be conducted after a HAZOP study as the outcome of the HAZOP can be used as input to LOPA. In particular, high severity hazards identified in HAZOP should be reviewed closely in LOPA. Initiating event and IPL can also be referenced from HAZOP when relevant.

    LOPA is most effective when conducted in design phase where changes to SIFs and IPLs (to achieve required SIL) can be implemented with minimum delays and financial expenditure.
