As Low as Reasonably Practicable (ALARP)
ALARP demonstration is part of the decision-making process in high hazard industry. The offshore industry has published guidance on the methods for making decisions in situations involving risk (UKOOA 1999), including ALARP demonstrations. This decision framework has been widely endorsed and adopted by several organisations worldwide.
What is ALARP demonstration?
There is no single, industry-recognised method to demonstrate risks are ALARP, however, it is generally accepted that the following elements are involved.
- Identification and consideration of a range of potential measures for further risk reduction through a workshop / structured brainstorm process
- Systematic analysis of each of the identified measures and a conclusion made on the safety benefit associated with each of them
- Qualitatively assess the cost and benefit associated with each candidate upgrade to determine whether or not it is worthwhile implementing
- Perform quantitative cost benefit analysis on those upgrades where qualitative analysis is insufficient to make the decision of whether or not to implement. This is done by calculating the Value to Prevent Fatality (VPF) for the candidate upgrade
- This is then used, in conjunction with other considerations, to determine whether the upgrade is practicable to implement
- The implementation (or planned implementation) of the identified measures
- Recording of the process and results
Bureau Veritas uses a standalone workshop that specifically targets risk reduction as a process to demonstrate ALARP.
An ALARP study is often the final stage of a formal safety report and focuses on the higher risk areas of a project when they have been quantified. The starting point for an ALARP study is a list of the key risk drivers which is tipically generated from the QRA.
Our approach for ALARP
Why choose Bureau Veritas for ALARP?
The output from an ALARP workshop can have a significant influence on the management of safety and personnel risks. All workshop actions must be tracked and closed. Our engineers are experienced at facilitating this entire process having delivered countless workshops around the world in order to satisfy various local regulatory requirements.
ALARP - FAQ
I have already completed a QRA, why do I need an ALARP workshop?
There are several reasons to perform a team evaluation on the tolerable risk criteria of a facility. This exercise enables open challenge of assumptions and control measures to better determine, justify, and prioritise risk reduction measures. It also enables the key risks to be communicated and understood by a wider audience which help improve competence management on site and future decision making during operations and maintenance.
