Preliminary results of RBI user survey
TWI has completed an extensive survey to gain a better understanding of advanced plant life management practices and the practical needs of plant operators. The work is part of a long-term joint industry project (JIP) to consolidate user experience on currently available risk-based inspection (RBI) and maintenance (RBM) practices, as well as fitness-for-service (FFS) assessment procedures.
The survey was open to sponsors and non-sponsors of the JIP.
A small selection of preliminary results of the survey (concerned with RBI only) is presented below.

Has your company previously implemented, or is your company considering implementing RBI/RBM?
The majority of all respondents' companies (69%) have 'previously implemented' RBI/RBM or are 'currently implementing' RBI/RBM. The fossil fuel power generation, nuclear power generation and oil & gas transportation sectors are the only sectors that have not previously implemented RBI/RBM. However, all sectors have indicated that they are currently implementing RBI/RBM. Oil & gas production (onshore and offshore) and multi-sectoral companies have progressed the furthest with RBI/RBM implementation. Petrochemical, oil and gas refining, fossil fuel power generation and chemical companies have the largest proportion of respondents considering implementation.
Use of RBI/RBM for several types of plant - ranking of plant by 'used and intend to use again'
General pressure vessels, process piping and shell and tube heat exchangers are expected to be the types of plant to which RBI/RBM is most often applied.
Structures, safety relief valves and pumps, turbines and compressors are expected to be the types of plant to which RBI/RBM is least often applied.
Use of three RBI/RBM methods - ranking of industry by 'used and intend to use again'
The oil and gas transportation and multi-sectoral companies appear to have made the most use of all RBI/RBM methods and intend to continue to do so in future. The petrochemical and oil refining sectors have made the least use of all of these methods.
