Advanced RBI software for optimising plant inspection

plant-wide risk audit enables

inspection resources to be risk-focused

optimum inspection intervals are formally obtained based on an implicit time dimension of risk

risk mitigation measures are signalled and selected to meet inspection frequency targets

highly user friendly decision support tool in accordance with the new API RP 580

Industry is recognising that benefits may be gained from adopting formal risk-based inspection (RBI) approaches to plant integrity management through improved targeting and scheduling of inspection and maintenance effort.

RISKWISE for Process Plant™ assesses the likelihood and consequence of failure for fixed equipment and piping and

produces a relative risk ranking for plant equipment is convenient to use and can be easily learned as the risk model allows qualitative as well

as quantitative input includes a regular updated database with all relevant damage mechanisms, as well as

guidance on formulating the consequence of failure allows the user to appraise or focus/defocus the likelihood and consequence attributes for

each component, eg the level of inspection and maintenance and thus mitigate the risk of loss or optimise the current inspection programme

identifies the most likely damage locations in each component and allows inspection to be properly targeted

determines the risk of failure with time which provides the rational basis for establishing the optimum period between major inspections

Benefits in brief improved safety increased availability reduced inspection costs and risk of failure a true inspection/maintenance planning tool rather than only

a risk analysis tool

RISKWISE™

RISKWISE™ is a TWI software product

Key features user-friendly software, fully

transparent – ensures buy-in by users

audit team approach – accommodates plant experience

interfaces with existing inspection data management systems

time-based risk auditing module – equipment ranked by risk and remaining life

inspection frequency based on formal reliability rules – remaining life indicator (RLI) module

focus/defocus module – facilitates selection of optimum measure

fully auditable output – acceptability to insurers/regulators

Implementation approach RISKWISE™ can be applied to all types of process plants including oil/gas production facilities, oil refineries, gas plants, petrochemical and chemical plants. The following approach is normally adopted:

1. customise and populate software to the specified plant

2. install the software 3. training in the implementation and

functionality of the software 4. back-up consultancy support as

required.

Equipment requirement PC (stand-alone or networked) MS-Windows operating system (NT 4.0, or higher)
