Abstract

Numerous pipeline failures have occurred due to the drastic increase in oil and gas product distribution pipelines over the last three decades. Corrosion is a significant factor in the failure of offshore gas pipelines. It is necessary to maintain the integrity of the offshore transmission system, one of which is the riser, for the product to be adequately distributed. The purpose of this study is to ensure the riser's reliability by conducting a risk assessment of the probability and consequences of equipment failure, mitigating the impact of failure risk, and developing a more optimal inspection plan. The API 5L Grade X60 gas riser pipe is the subject of this study. The quantitative Risk-Based Inspection (RBI) technique was used in 2016 following the API 581 standard. This quantitative approach is founded on a numerical value model constructed using validated operational data and inspection results. The risk assessment indicates that the gas riser pipelines will have a high-risk level (5D) for the splash zone segment and a medium-risk level (2D) for the above-and below-water segments. The recommended inspection plan for the gas riser pipeline is one year after the risk-based inspection assessment.

Abstract

The oil and gas industry can contribute significantly to sustainable development by mitigating negative environmental impacts, such as equipment failure. Numerous pipeline failures have occurred due to the dramatic expansion of the oil and gas product distribution pipeline network, which is a significant factor in the offshore gas pipeline network's failure. In general, compared to other equipment types in the industry, planning inspections presents more challenges. Due to a lack of jurisdictional requirements regarding inspection intervals and piping methods. This research aims to ensure the reliability by conducting a risk assessment of the likelihood and consequences of equipment failure, mitigating the impact of that risk, and developing a more optimal inspection plan. This study is focused on API Class 5L Pipe 3" GL BO3-52520. The Routine Inspection Technique (RBI) was implemented in 2016 following the API 581 standard. This semi-quantitative approach is built based on operational data and validated inspection results. According to the risk assessment, the pipeline will have a Medium risk level, with metal losses occurring in each segment. Four years after the risk-based inspection assessment, the recommended inspection plan for gas pipelines is four years.
