In-Depth Information
Individual asset inspection and reliability analysis
Asset inspection (through visual, nonintrusive and intrusive means)
and associated reliability analysis (failure modes and loads).
Sources
(e.g. water levels
waves, correlation, etc.)
System analysis and risk attribution
Analysis of asset system (Source/Pathway and Receptor) and
attribution of risk to individual assets within the asset system.
Pathways
(e.g. asset location,
geometry, condition,
topography, etc.)
Optimisation of management strategy
Develop adaptive and optimum strategies that afford robust
performance against a wide range of possible future scenarios.
Common databases
Central databases evolve as new
data are gathered and analysis
undertaken. Quantified
confidence within the data held,
and its time history, is recorded
(including risks and costs).
Receptors
(e.g. location,
vulnerability and
damage valuation, etc.)
Review and decide
Review preferred actions and programme implementation
Costs
(e.g. option costs, land
value, unit rates and
cost functions, etc.)
Act
Act to reduce uncertainty (gather data or further modelling) - act to
reduce risk (intervene to improve assets)
Policy constraints
(e.g. from higher level
plans and legal
requirements)
Record and Monitor
Monitor, record and update evidence
