Integrity Operating Windows (IOWs)

API RP 580 Section 6.4

“Operating within the boundaries is critical to the validity of the

RBI study….”

API 510 Section 5.4.2

“Potential of damage is dependent upon its material of

construction, design, construction, and operating conditions. The

inspector should be familiar with these conditions...”

API RP 584

1.1 “Understanding of process/operating conditions and resulting

damage mechanisms are required in order to establish and

maintain an inspection program …….”

1.6 “….integrity operating windows (IOWs) are limits on process

variables that need to be established and implemented in

order to prevent potential breaches of containment that might

occur ….”



Define Integrity Operating

Define Mitigation Strategy

Execute Strategy

Evaluate and

Communicate Results

Collect or Update Asset Data

Perform Risk

Identify Potential

Degradation Mechanisms

API RP 584, Section 1.8

Examples of Multiple IOW Limits for Furnace Tubes designed for 950 °F

• 1000 °F - First IOW Limit. Shortened service life. Operators directed to

regain control of furnace firing.

• 1050 °F – Second IOW Limit. Operators directed to take more

immediate actions and/or shut down the furnace.


IOW–Need for Content Development

Key Questions while Developing IOW Policies:

• Optimal Level of Monitoring?

• What are my Industry Peers doing?

• Excursion follow up process?

• KPIs/Dashboards for IOW Management?

• Excursion Data in Meridium vs. Process

Historians?


Proposed IOW Content Structure

Category 1 - IOW Policies

• IOWs Specific to Damage Mechanism.

Limits based on Established Industry Guidelines.

Examples: Creep, HTHA etc.

Category 2 - IOW Policies

• IOWs Specific to Damage Mechanism.

Limits Dependent on Plant and Process Design

Examples: Amine Unit, etc.

Category 3 - IOW Policies:

• IOW Policies not specific to Damage Mechanisms.

Example: Compare Real Time Corrosion against

Predicted Corrosion Rates.


Meridium Demos

• Category 1 IOW Policies



IOW - DEMOS


Proposed IOW Content Development

Approach

Collaborative Approach with Selected Clients

in each Industry Vertical – Refining

– Petrochemical

– Oil and Gas Production

– LNG

Category 1 - IOW Policies: – Agree on a List of Damage Mechanisms and Methods.

– Develop and Validate Policies.

Category 2 - IOW Policies: – Develop Policies for Process Units with Clients

– Genericize for Other Clients.

Category 3 - IOW Policies: – Develop and Validate policies.


Proposed IOW Content Delivery

Approach

Category 1 & 3 - IOW Policies:

- Packaged Solution Clients: - Policies delivered to Client with Documentation

- Clients apply policies to Assets in their database

- Non Packaged Solution Clients: - Policies delivered to Client with Documentation

- Clients modify Policies based on their configuration (or use

Meridium Professional Services)

- Clients apply policies to Assets in their database

Category 2 - IOW Policies: – Policies delivered to Client with Documentation

– Policies reviewed by Client and Modified based on their Process

Design

– Clients apply policies to Assets in their database
