RISKWISE - Risk Based Inspection and Maintenance (RBI and RBM) Software

unit-wide risk audit enables repair and maintenance resources to be risk-focused
optimum inspection periods are formally obtained based on an implicit time dimension of risk
risk mitigation measures are signalled and selected to meet inspection frequency targets
user selectable application display language

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

RISKWISE for Boilers™

assesses the probability and consequence of failure for equipment items and produces an itemised risk and remaining life profile for each plant unit
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 probability and the consequence of failure
allows the user to appraise or focus/defocus the probability 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 a formal basis for assessing remaining life and hence establishing the period between maintenance and inspection outages

Benefits in brief

improved safety
increased availability
optimum maintenance spend
facilitates increased run times, reduced outage time/costs and fewer forced outages
a true maintenance planning tool rather than only a risk analysis tool
links with existing inspection and maintenance records or software
English, Chinese, Japanese and Spanish language versions available

Key features

user friendly software, fully transparent - ensures buy-in by users
audit team approach - accommodates plant experience
interfaces with computerised maintenance management systems
time-based risk auditing module - equipment ranked by risk and remaining life
maintenance frequency based on formal reliability rules - remaining life indicator (RLI) module
focus/defocus module - facilitates selection of optimum mitigation measures
fully auditable output - acceptability to insurers/regulators

Implementation approach

RISKWISE™ can be applied to all types of boilers including heat recovery steam generators and can be extended to turbine plant and balance of plant areas. The following approach is normally adopted:

customise and populate software to the specified plant
install the software
training in the implementation and functionality of the software
back-up consultancy support as required.
