Oil and Gas Pipeline Integrity Management

Implementing an effective pipeline integrity management system to ensure effective life extension of ageing pipelines

• Implementing protective measures to ensure that the risk of loss of pipeline integrity meets ALARP criteria
• Adequate review, assessment and update of the pipeline integrity process to appropriate current codes and standards, drawing on the latest research findings where appropriate, to ensure duty holders maintain pipeline integrity good practice
• An assessment process for modifications, changes in mode of operation and damage sustained to pipelines;
• Revealing a range of suitable and sufficient integrity control activities which cover inspection, monitoring, testing and integrity assessments in order to detect and safely manage degradation;
• An appropriate verification system to provide assurance of the pipeline integrity management process and the significance of deterioration and damage relating to the potential effect on the functionality, availability, reliability and safety of safety critical elements (SCEs).

• Defining and understanding the condition of specific pipeline systems, prior to investigating the issues that could be considered a limiting factor to achieving the maximum lifetime of system
• Addressing specific threats which are to be managed in the Integrity Management System
• Viewing pipeline integrity management as an ongoing process: evaluating threats and deficiencies on a continuous basis to maximise the useful life of the asset

Pragmatic survey and repair solutions for external corrosion on old pipeline.

• Paper will show how cost-effective surveys and repairs can be made to old onshore pipelines to either re-activate them or extend their useful life
• Modern instrumentation and well-proven survey techniques allow rapid surveys and risk classifications
• Priority matrix identifies locations for investigations
• Modern copolymers used for coating repair and field joint coating compatible with cathodic protection
• Corrosion inside casings can be eliminated with copolymers
• Retro-fit cathodic protection to stop external corrosion
• Effects of stray current interference from dc tractions systems (railways, trams) as well as ac interference effects can be easily analysed using modern techniques
• New CEN, CENELEC and ISO standards available to provide guidance
