13th International Conference on
Pipeline Protection
Edinburgh, Scotland: 29 September - 1 October 1999

Introduction

One of the biggest challenges facing oil, gas and process industry today is how to maintain the safe and economical operation of pipelines beyond their original design life. There have been tremendous advances in the techniques and materials available in recent years, but there is still demand for more information on the latest developments.

Since it was established in 1975, this conference has presented the latest and most important information on developments in pipeline protection. It has enabled operators, consultants, contractors, designers, suppliers and researchers to share experiences across a wide range of industries.

The condition of the pipeline is critical to its continued safe, efficient and environmentally friendly operation. Where deterioration has occurred, rehabilitation is required. For new pipelines, employing the latest techniques helps optimise the installation for economic performance and extended working life.

Technical staff will not achieve maximum benefit from the most up to date knowledge without understanding the costs and benefits of the latest pipe materials, coatings, jointing techniques, inhibitors, and monitoring and cleaning systems.
