As assets age. time dependent degradation. the operators have several new challenges to consider when required to operate beyond the design life such as:  Changes in integrity. third party damages).g. e.g.

Corrosion management is not just about sending NDT technicians on the site and painting pipework. corrosion mitigation. Effective management of corrosion control and monitoring activities are key elements of Asset Integrity Management. Integrity & Corrosion Issues No leaks or emissions 20% annual reductions Reduce/elimivate emissions Clear Policies & Objectives Assess skills and competence Define roles & responsibilities Ensure co-operation & communication Organisational Structure & Responsibilities Identify hazards & assess risks Agree targets.+CORROSION MANAGEMENT SYSTEM (CMS) Corrosion Management System (CMS) is involved in a range of activities including corrosion prevention. Inspection. corrosion monitoring and inspection. Corrosion management is a cross-discipline activity (Technical & Non-Technical). Roles and Responsibilities. Corrosion Awareness. Monitoring. Procedures & Implementation Proactive measurement using regular checks to show controls are working Reactive measurement identifies why performance was substandard Review activities & trends Check for compliance Learn from experience & make changes Getting it Right Reports used to achieve improvements Reviews used to provide correction Measure Performance Yes Review of Data & Performance No Meeting the control criteria? Independent Audit 8 . LifeTech Engineering has developed a detailed corrosion management strategy based on HSE UK Corrosion Management document-OTO 2001/044-including the following main activities:  Corrosion Risk Assessment  Corrosion Control Programme  Implementation of the Corrosion Control Program (Mitigation. processes & systems Set standards for measuring performance Planning. Data Management and Material Degradation Reporting)  Performance Assessment  Design/New Projects/Equipment Changes  Experience and Lessons Learned Health & Safety. Repairs.

 Maintaining a flow of information between parties.  Corrosion risk assessment will also act as a tool to identify any weaknesses in the existing corrosion control programme and prompt the risk reducing actions.  Corrosion Risk Assessment (CRA). 9 .  Improving corrosion control. and.+CORROSION RISK ASSESSMENT (CRA)  Corrosion is the main reason for conducting technical inspections.  The output of a Corrosion Risk Assessment will feed into the Risk Based Inspection and Corrosion Management systems  The Corrosion Management system will be used to mitigate or control corrosion by:  Monitoring corrosion control performance. which may be embedded within the Risk Based Inspection is the process of identifying and quantifying the possible risks due to corrosion.  Identifying and resolving corrosion management issues.  The purpose of the corrosion risk assessment is to identify and prioritise the effect of various material degradation mechanisms on the asset.

A typical FFS assessment may involve several engineering disciplines. The outcome of a fitness-for-service assessment is a decision to run as is. The equipment or system in question may contains flaws or other damage. which can be used to set future inspection intervals and to budget for capital expenditures when existing equipment is to be retired. alter. re-rate. 10 . or retire the equipment. A remaining life analysis may also be performed as part of the assessment.+FITNESS FOR SERVICE (FFS) ASSESSMENT Fitness-for-service (FFS) assessment is a multi-disciplinary approach to determine whether equipment Is fit for continued service. repair. or may be subjected to more severe operating conditions than anticipated by the original design. An experienced LifeTech Engineer takes the lead role in performing the assessment. and it requires collecting data from a number of sources. he will rely on other LifeTech Engineers to provide crucial data and expertise.

LifeTech uses a Risk Based approach for RCM Methodology which includes the following steps:  Screening  Failure Mode and Effect Analysis (FMEA)  Risk evaluation  Strategy development 11 . RCM incorporates decision logic to ascertain the safety and operational consequences of failures and identifies the mechanisms responsible for those failures”. and asset protection  Phase 2: specify the requisite PM tasks for the equipment identified in phase 1. It is the best known proven method for developing a preventive maintenance (PM) program for any type of plant or facility.  The Three Phases of an RCM Based Preventive Maintenance Program:   Phase 1: identify equipment important to plant safety.  “RCM is defined as a set of tasks generated on the basis of a systematic evaluation that are used to develop or optimize a maintenance program.  Phase 3: properly execute the tasks specified in phase 2. generation (or production).+RELIABILITY CENTERED MAINTENANCE (RCM)  RCM is a common sense approach for achieving reliability.
