Introduction

Petroleum refineries, petrochemical and process plants have hundreds of pieces of equipment and thousands of meters of piping that handle hazardous and corrosive fluids and operate at wide ranges of temperatures and pressures. Plant integrity and reliability can only be achieved if this equipment and connected piping are designed properly and they remain fit for continued service between scheduled turnarounds.

The design and fabrication of process equipment and piping systems are carried out in accordance with industry codes and standards. Fabrication and welding processes are subjected to defined examinations and inspections to ensure that any deficiencies found are resolved so as to meet the acceptance criteria of the respective codes.

Once the new equipment and piping are put in service, they get exposed to the process fluids and start to undergo deterioration such as corrosion at various rates depending on the materials of construction and service conditions. It is therefore essential to know their current condition and the degradation rate so that appropriate repairs and maintenance can be carried out in a timely manner to prevent failures. Effective inspection and evaluation of the inspection data are vital for this purpose. The integrity of the plant cannot be achieved without effective inspection.

Regular and reliable inspections are an integral part of any effective industrial plant maintenance program. The success of such a program relies greatly on the Non-Destructive Inspection (NDT or NDE or NDI) techniques used. Non-destructive inspection (NDT) techniques detect flaws that can cause potential failure in the future. This way, NDT provides information on the integrity of the pipeline as well as a measure of its current safety margin. Hence, it is important to understand the scope and limitations of the common and advanced NDE tools that are available in order to maximize the effectiveness of each of the scheduled inspection activities.

Furthermore, in today’s competitive environment plant operators need to reduce maintenance costs by minimizing downtime. Effective inspection contributes significantly to this objective.

In this comprehensive and integrated course, you will gain a clear understanding of the damage and degradation mechanisms that affect process equipment and piping and progressively adversely affect their condition and fitness for continued service. You will also understand that effective inspection is the backbone of plant integrity and that it has significant impact on EHS and financial performance of the company. The course will increase your awareness of industry codes and best practices related to inspection, repair and alteration of process equipment and piping including ASME BPVC and various API codes, standards and recommended practices. The course also provides a sound and concise coverage of fitness-for-service assessment methodologies and API/ASME FFS standards to enable making run/repair/replace decision about the damaged equipment/piping. The course then covers the main industry codes and practices for repairs and alterations to enable you to achieve business focused repairs and lower maintenance costs.

Objectives

The objectives of the course are:

• To increase delegates awareness of the degradation and damage that affects equipment and piping in service and that knowledge of their condition and remaining safe life are crucial for safe and reliable plant operation.

• To highlight the important function and significance of effective inspection on plant integrity, financial and EHS performance.

• To make delegates aware of the benefits of risk-based inspection (RBI) and maximizing non-intrusive inspections (NII) on improved reliability and reduced maintenance costs.

• To provide a clear understanding of the fundamentals of nondestructive inspection and the major NDT methods, their capabilities, and limitations.

• To make it clear that all deficiencies found by inspections must be evaluated and that some of the deficiencies may be deemed to be acceptable obviating the need for immediate repairs.

• To provide methodologies for performing fitness-for-service assessments of damaged equipment/piping with the objective of making run/repair/replace decisions.

• To increase awareness of applicable industry codes and best practices covering inspection, repair, and alteration of process equipment and piping.

Benefits

• The delegates will gain sound and integrated understanding of the key aspects relating to inspection of process equipment and piping throughout their life cycle, and that inspection is the backbone of plant integrity.

• They will gain a better understanding of the intent of the major industry codes and best practices pertaining to inspection, fitness-for-service assessment and repairs of process equipment and piping.

• Delegates will achieve a clear understanding and skills to perform fitness-for-service assessments and thus make value-added contributions to the company performance through technically sound and business-focused run/repair/replace recommendations.

• The delegates will gain a better understanding of the common repair methods and their advantages and limitations to safeguard against related failure and to avoid excessive repair costs.

Results

• The company will achieve improved reliability through the implementation of effective inspection strategies including risk-based inspection, optimum non-intrusive inspection and use of advanced NDT methodologies.

• The company will achieve a measurable reduction in failure incidents and consequently improved EHS performance through effectively evaluating and ensuring pressure equipment and piping are fit for continued service between scheduled turnarounds.

• By using best industry practices for effective inspection, fitness-for-service assessment, and business-focused repairs the company will be able to achieve lower maintenance and repair costs while simultaneously improving reliability and complying with applicable codes and standards, and other regulatory requirements.
