The integrity of offshore pipelines is paramount for the operational efficiency and environmental safety. Reliable real-time leak detection is essential for mitigating environmental risks, minimizing financial losses, and ensuring the safety of personnel and infrastructure. This paper explores the applications of two distinct technologies: statistical volume balance and negative pressure wave leak detection at Equinor.

Through detailed case studies on oil, gas and multi-phase pipelines, the paper will illustrate how these technologies have been successfully integrated into Equinor's pipeline operations, highlighting the tangible benefits achieved in terms of leak detection sensitivity, response time, and overall reliability. Additionally, the paper will share the key success factors in operating a real-time leak detection system and the strategies employed to overcome challenges during implementation. During operation the close collaboration between operator and vendor is beneficial.

In conclusion, the paper underscores the importance of reliable real-time leak detection for offshore pipelines and showcases the exemplary collaboration between Equinor and Atmos, paving the way for innovative solutions and enhanced safety measures in the oil and gas industry.
