What is a Reliability Engineer?

The primary role of a Reliability Engineer is to identify and manage asset reliability risks that could adversely affect facility manufacturing processes. A Reliability Engineer is an expert who specialises in ensuring that machinery and methods are reliable and efficient. Reliability Engineers are responsible for developing strategies to prevent failures and minimise facility downtime. 

Reliability Engineers work closely with maintenance teams to design and implement maintenance plans, monitor equipment performance, and identify potential issues before they become significant problems. A Reliability Engineer is also involved in developing new equipment and processes to improve reliability and efficiency in manufacturing facilities.

In recent years, there has been a significant shift in how the commissioning of new facilities is approached. The following are the main reasons:

Key Responsibilities of a Reliability Engineer

  • Developing and implementing maintenance strategies to prevent equipment failures.
  • A Reliability Engineer provides leadership, direction and guidance in developing, communicating and managing Reliability Improvement Programs.
  • Managing and supporting asset improvement and reliability initiatives from concept to implementation and reporting on achieved outcomes.
  • Monitoring equipment performance and analysing data to identify potential issues.
  • Collaborating with maintenance teams to design and implement maintenance plans.
  • Conducting failure analysis: When a product or system fails, the reliability engineer is responsible for investigating the cause and determining how to prevent it from happening again. This can involve analyzing data, conducting experiments, and consulting other experts to develop solutions.
  • Performing and supporting Root Cause Failure Analysis and troubleshooting for recurring technical failures. Conducting risk assessments to identify potential failure modes.
  • Administering predictive maintenance program through non-destructive testing methods Performing life cycle asset management, including new asset integration, asset preservation, and retirement of assets.
  • Developing and implementing reliability-centered maintenance (RCM) programs.
  • Developing and implementing condition-based maintenance (CBM) programs.
  • Participating in developing new equipment and processes to improve reliability and efficiency.

The Importance of a Reliability Engineer in the Pharmaceutical / Biologics

The role of a Reliability Engineer is crucial in ensuring that manufacturing facilities operate smoothly, and that equipment is maintained to minimise the risk of facility downtime. A Reliability Engineer can help to:

  • Improve equipment reliability and efficiency

Frequently Asked Questions about Reliability Engineering

A: The main objective of reliability engineering is to ensure that a system or product operates consistently and dependably over time. Reliability engineering is a multidisciplinary field that combines principles of engineering, mathematics, and statistics to design, develop, and maintain systems that meet or exceed performance and safety requirements.

Reliability engineering seeks to minimize the likelihood of failure and downtime in a system or product, while maximizing its availability, maintainability, and safety. This involves identifying potential failure modes and their root causes, evaluating the impact of failures on the system or product, and implementing measures to prevent or mitigate failures.

The ultimate goal of reliability engineering is to improve the overall quality and performance of systems and products, while reducing costs and increasing efficiency.

A: A bachelor’s degree in engineering or equivalent qualification is usually required, with a focus on reliability, maintenance, or a related field. Additional certifications, such as Certified Reliability Engineer (CRE), can also be helpful.

RCM is a method of developing maintenance strategies based on the reliability characteristics of equipment. It involves identifying potential failure modes, developing strategies to prevent or mitigate them, and determining the most effective maintenance approach.

CBM is a maintenance approach that uses real-time monitoring data to determine when maintenance is required.
