Asset Integrity & Maintenance

Asset Integrity is fitness to function safely and reliably for the full remaining life of the asset.

Codes, standards, legislation and work processes to be complied with in demonstrating integrity, are provided in the Asset Integrity Management System ( the ‘How?’ of asset integrity).

Evidence of integrity is demonstrated by the Asset Integrity Case (the ‘What?’ of asset integrity) which documents the condition of the asset, system by system, the exposure arising from system condition (usually relating to Safety Critical Elements), and the inspection, maintenance and repair programme (IMR) to maintain integrity.

The Asset Integrity Management System, together with the Asset Integrity Case, comprise the Asset Integrity Manual, the responsibility for which typically lies with the asset’s Head of Technical Safety.

EPConsult Energies have the expertise together with proven templates for planning and resourcing work processes to organise your inspection and maintenance programmes into a world class asset integrity management system and, asset integrity case.

Here is some more detail.

Asset Integrity Management System (AIMS)

Asset Integrity Management is the process of assuring the production facility is fit for its current and future purpose. Broadly speaking, asset integrity management can be applied to HSE, and production regularity.

Our approach to asset integrity is to develop an Asset Integrity Management System (AIMS) which consists of the 7 functions of a Quality Management System

1. Strategy and objectives

2. Procedures and standards

3. Planning

4. Execution

5. Reporting and analysis

6. Compliance and auditing

7. Feedback and improvement

Each of these broad headings (level 1) are subdivided into activities (level 2) and deliverables (level 3).

The level 3 deliverables typically include: roles and responsibilities; job descriptions; inspection and maintenance procedures; flow charts for change management and approvals; and many more, to provide the asset manager with the tools needed to deliver technical integrity.

Finally, EPEn recommend developing RACI (S) charts to ensure that roles and responsibilities of participating organisations are clearly defined.

A key stage in integrity management is the assessment of criticality, both safety criticality (Safety Critical Elements) and production criticality - for optimum maintenance management.

Asset Integrity Case (AIC)

The Asset Integrity Case (AIC)compiles the evidence required to demonstrate that the asset has Technical Integrity.
Content of an AIC include:
1. System description
2. System condition
3. System impact
4. System exposure
5. IM strategy/plan
6. Corrective action plan
7. Asset integrity statement

Asset Integrity Manual

Together, the AIM’s and the AIC comprise the Asset Integrity Manual
