Review of Subsea Pipeline Rehabilitation, Flow Assurance Strategies, and Internal Pressure Stabilization Technologies
Abstract
Subsea pipelines are a vital component of offshore oil and gas operations, facilitating the transportation of hydrocarbons over long distances from deepwater fields to processing facilities. However, the integrity, efficiency, and safety of these pipelines are challenged by environmental factors, operational stresses, and technological limitations. This paper provides an in-depth review of subsea pipeline rehabilitation, flow assurance strategies, and internal pressure stabilization technologies, which are critical in maintaining pipeline functionality and preventing costly failures. The rehabilitation techniques discussed include advanced inspection methods, subsea welding, and repair clamps, while flow assurance strategies such as chemical injection, insulation, and heating systems are highlighted as key tools for mitigating issues like hydrate formation and wax deposition. Additionally, the review explores the importance of internal pressure stabilization and the technologies used to maintain optimal flow performance, including pressure boosting, slug catchers, and gas lift systems. The paper also addresses the challenges faced in deepwater and ultra-deepwater environments and discusses emerging innovations in these technologies. Finally, the paper emphasizes the future of subsea pipeline technologies, with a focus on sustainability, automation, and real-time monitoring, providing recommendations for improving pipeline integrity and operational efficiency.
