Advanced Risk Based Inspection (RBI) software for optimising inspection and maintenance of storage tanks
- unit-wide risk audit enables repair and maintenance resources to be risk-focused
- safe 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 maintenance (RBM) approaches to integrity management of above-ground storage tanks through improved targeting and scheduling of inspection and maintenance effort.
RISKWISE for Tanks™
- stores tank information in the Item Properties and Materials screens. This information can be easily integrated with asset information in other applications, via the in-built RISKWISE™ 'Import Wizard'
- captures all relevant historical inspection and maintenance history in the Inspection Methods screen for subsequent use in the identification of tank damage mechanisms prior to the risk assessment
- captures the location of all active and potentially active damage mechanisms within each storage tank
- assesses seven likelihood (probability) of failure factors and nine consequence of failure factors, for each tank
- presents the results of the risk analysis for each of the damage mechanisms, over the three forward time intervals, as well as the resulting remaining life indicator (RLI) which defines a safe inspection interval
- presents RBI assessors with a risk action plan from which the most suitable risk mitigation options, for critical tanks, can be evaluated
Benefits in brief
- improved safety
- optimum maintenance spend
- facilitates increased inspection intervals
- incorporates results of acoustic emission tests
- 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 existing inspection 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
 Example of inspection methods input
Implementation approach
RISKWISE for Tanks™ can be applied to all types of atmospheric storage tanks. 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.
 Risk summary and remaining life indicator (RLI) for a single tank
Equipment requirement
- PC (stand-alone or networked) with MS-Windows operating system (NT 4.0, or higher)
