Introduction

In order to proactively improve and enhance the safety reliability and profitability in chemical plants and oil field related plant and machinery, it is necessary to understand where why and how the corrosion related mechanisms cause damage which eventually lead to sudden failures. Such an understanding of failure mode helps to establish plant reliability and safety at optimal cost.

Objective

This course aims to provide the participants with an understanding of why and how corrosion occurs, the metallurgical and environmental factors influencing corrosion, and practical methods of corrosion control and failure prevention.  Participants will be able to grasp the basic concepts related to corrosion, metallurgy and failure analysis, and to apply the state-of-the-art technology in their workplace with an aim to achieve low cost reliability.  This course is designed to take a break and learn why problems persist in different parts and plants and machinery and how to address them by careful online monitoring

Audience

This course provides an excellent avenue for process engineers operations staff, maintenance engineers, inspection and laboratory personnel, and those involved in failure analysis to update their appreciation of corrosion and the awareness of the emerging technologies for corrosion control and failure prevention.  The presentation is made in simple style for all levels of engineering staff

Certificate

MAESTRO CONSULTANTS Certificate of Completion for delegates who attend and complete the training course

Methodology

Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
