Corrosion challenges can be internal, external or a combination of both and consequently 360integrity™ has ‘integrated’ tools to manage them with a high degree of specificity. With the following tools we can easily monitor and control the containment challenges associated with high criticality lines, vessels, process systems and structural plant elements.
Inspection Planning and Reporting is an essential aspect of 360integrity™, since this is one aspect of feedback that can hugely affect the handling of Corrosion Criteria. There dedicated functionality within 360integrity™ for the planning, scheduling, implementation and recording of all inspection findings, with (where appropriate) automated processing of that data, to refresh the Corrosion Alarms, Criticalities, Threats and Maintenance Schedules.
Prioritise and sub=prioritise inspection workloads by applying confidence-factors against the anticipated/known condition or all substrates. Define the condition as one of 3 separate levels, High, Neutral & Low.
High confidence – we are 100% confident that we know and understand the condition of this component.
Neutral Confidence – We expect the substrate to be in this condition, but cannot be certain.
Low Confidence – The component has not been inspected recently and we do not know its current condition.
By assigning these factors, it becomes clear where inspections should be immediately targeted.
In this process ‘any-and-every’ element in the database can be utilised in the development of Criticalities. Using this approach, a set of complex rules and current best-practice can be defined to indicate where corrosion challenges may be discovered on current plant – and even future new plant additions, and applied over the life of the facility.
The development and management of ‘Qualitative/ Quantitative Criticalities’ is an essential aspect of Corrosion Control, and 360integrity™ has four separate modes of Criticality application, each is user selectable and dependant on the style of integrity management in place.
RELATIVE RISK & CRITICALITY DEVELOPMENT: Here each component is classified against a set of pre-defined criteria and the Criticality is automatically recalculated based on changing data. An advantage of this method is that discrete components of the plant can be individually and quickly assessed.
QUALITATIVE CRITICALITY ASSESSMENT: The Qualitative approach offers the most accurate picture of the Criticality of your plant, it’s often based on a Knowledge Specification particular to your plant. RISCm™ can easily determine these assessment results to build useful inspection and maintenance plans and model potential threats. Obviously Internal and External corrosion can be separately managed and all corrosion ‘degradation’ and ‘mitigation’ factors considered.
Alternatively, Library-based criticality deployment is a simple to set-up and rapid to deploy technique where another external tool has been used to develop the Criticalities and RISCm™ then simply applies them.
The Threat Manager supports the user in determining where threats and hazards to the plant may exist. It’s a process of analysis of all data held in RISCm™, and demonstrates which items, areas and process’ may be subject to specific threats. This module is particularly useful to target substrates where containment may be at risk from little-known or un-researched corrosion challenges.
CORROSION ANALYSIS & MAPPING
One of the most difficult challenges in Corrosion Management is getting a 'big picture' overview of where and how severe current corrosion is and where it may become problematic in future. In 360integrity we have developed a set of Analysis tools that demonstrate where the rates of corrosion are worst and enable an immediate review of those items.
Mapping corrosion is another procedure 360integrity makes easy. Rather than having a long drawn out process to figure out what your challenges are - almost all plant criteria can be modelled, on one page and one chart. Imagine being able to see 'instantly' how your plant looks based on any combination of Location, Service, System, Tag, RBA, Criticality, Threat, Metallurgy, Process CUI, Corrosion Allowances, Trends and even H2S (and more) and you'll get an understanding of how powerful Corrosion Mapping can be.
WALL THICKNESS MANAGER
Adjustable settings for Wall Thickness Alarms are used to flag substrates which may become problematic in the future, used to target ‘hot spots’ and cost effectively plan Inspection programmes or maintenance attention. Corrosion rates are graphed and trends can easily be shown and monitored, to be incorporated into KPI views or Threat Models.
