I think that listing is confusing tools with RA methodologies. The two examples you mention are important ingredients in any good RA but they are certainly not complete RAs themselves.

The PHMSA has recently criticised how Integrity Management Plan (IMP) risk assessments (RAs) for pipelines are being conducted. Do you also see problems?
There is a wide range of practice among pipeline operators right now. Some RA is admittedly in need of improvement, not yet meeting the intent of the IMP regulation. However, I believe that is not due to lack of good intention, but rather incomplete understanding of risk. Risk is a relatively new concept, and is […]

Articles <!– Where is the Risk Control Strategy? –> Is formal risk assessment helping me?

So previous chapters have already identified risk mitigation opportunities. Reducing exposure, increasing mitigation or […]
