Introduction

Ref No:        WC024
Title:            Corrosion Prevention In Oil & Gas Industry
Start Date:   04 September 2022  End Date: 08 September 2022  
Venue:         Dubai, UAE
Fee:             $4,500

In any of the 5 star hotels. The exact venue will be informed once finalized.

The annual losses due to corrosion and the cost of rectification run to several billion dollars in most of the countries. High production under aggressive and extreme operational conditions necessitates the development of new materials which also have peculiar failure patterns. Thus mankind is on continuous experimentation with products and processes. Yet material failure not only entails in loss of production but loss of life as well. Prediction of failure pattern, residual life measurements, preventive measures are all approaches in corrosion studies for safe and economic operation of plant and machinery.

Objective

This course aims to provide the participants with an understanding of why and how corrosion occurs, and how the environment in the gas and oil installations is aggressive to iron and steel equipment, plant and structures. It is designed to give a practical approach to control corrosion, and prevent failures. Presented are the basic concepts of corrosion, the metallurgy of iron and steel, and the mechanism of failure. Participants learn the state of art of corrosion control and be able to apply it in day-to-day work, thereby ensuring safety, plant reliability and economy. It is an update of Corrosion problems which affect the oil and gas production and reduce the plant integrity. It necessitates an understanding that ageing plants can cause catastrophic failures and underlines the importance and methodology of inspection. This also imparts an awareness of the emerging technologies for corrosion control and failure prevention. Interactive discussions on photographs of plant failures and a working methodology of failure analysis reinforce the understanding of the theory taught.

Audience

Process Engineers, Inspection Personnel, Mechanical Engineers, Material Selection Personnel and Corrosion Personnel. For all technicians, supervisors and maintenance staff who are interested in knowing why some components fail more often than expected- A Corrosion awareness for all Plant Engineers who are interested in learning the fitness for service of plant and equipment they are handling- For Safety Engineers who are interested in health safety and environment in case of unintended plant failure-for Finance Managers who are interested in knowing what affects production and asset management- and for all those who want to know more about inspection and monitoring.
