Expert Insights: Safeguarding Renewable Energy Operations Through Tailored Inspection Strategies

Interview with Magdalena, Integrity Engineer at OGC Energy


In the renewable energy sector, ensuring the safe and efficient operation of assets is paramount. Recently, we had the opportunity to speak with Magdalena, an Integrity Engineer at OGC Energy, renowned for their expertise in asset integrity. Magdalena shared valuable insights on how OGC Energy supported a prominent player in the renewable energy sector, the Biodigestor Operator, in developing a comprehensive inspection regime for their assets. Let’s dive into the details of this project and the role OGC Energy played in ensuring compliance, mitigating risks, and driving innovation in the field of asset integrity.

1. Can you provide us with an overview of the Biodigestor Operator’s challenge?

The Biodigestor Operator faced a unique challenge of creating new written schemes of examination (WSE) for Digestate and Gas Storage Tanks, including a double membrane gas holder and associated piping. With these tanks having a significant capacity, meeting the Health, Safety, and Environment (HSE) requirements within a limited timeframe was crucial. Their primary objective was to establish a comprehensive inspection regime to ensure the safe operation and integrity of the storage tanks.

2. What was OGC Energy’s role in addressing this challenge?

OGC Energy played a pivotal role in providing key support to the Biodigestor Operator. Our dedicated team collaborated closely with the client, retrieving and meticulously analysing design and operational data. We conducted a thorough review of relevant legislation and regulations, such as PSSR 2000 and COMAH, while adhering to guidelines outlined in EEMUA Publication 231.

3. Could you explain the risk assessment process conducted by OGC Energy?

For each storage tank and associated equipment, we conducted a comprehensive risk assessment following API 581 and API 571 guidelines. This assessment meticulously identified credible internal and external damage mechanisms, thoroughly evaluating their likelihood of failure. Based on the identified risks, we tailored the inspection regime and determined necessary preparation steps for examinations, adhering to the HOIS-RP-103 guidelines.

4. How did OGC Energy optimise inspection strategies to meet the client’s requirements?

To optimise inspection strategies, we estimated inspection frequencies, considering safety requirements, asset condition, and the operators’ technical capabilities. By addressing surface preparation requirements and implementing necessary safety precautions, we ensured a comprehensive inspection method. Each inspection method was accompanied by extensive inspection instructions, outlining estimated inspection coverage, providing comprehensive guidance to the client.

5. What were the key outcomes of OGC Energy’s involvement in this project?

Through collaborative efforts and adherence to industry guidelines, such as EEMUA Publication 231, API 581, API 571, and HOIS-RP-103, OGC Energy facilitated the development of a comprehensive and tailored written scheme of examination (WSE) for the biogas biodigestors. This approach not only ensured compliance with regulations but also minimised risks, safeguarding the integrity and safe operation of the biodigestors.


As our conversation with Magdalena, an Integrity Engineer at OGC Energy, came to a close, it was clear that their expertise played a vital role in advancing renewable energy solutions. By developing tailored inspection strategies and leveraging industry guidelines, OGC Energy ensured compliance, minimised risks, and upheld the integrity of the Biodigestor Operator’s biogas biodigestors. OGC Energy remains dedicated to driving innovation in the field of asset integrity, supporting the sustainable growth of the renewable energy sector.
