The Advanced Infrastructure Integrity Model (AIIM) is a multivariate, multi-machine learning modeling technology applied to evaluate the integrity of offshore energy infrastructure (e.g., pipelines, platforms) in the Gulf of Mexico. Offshore energy infrastructure plays an essential role in ensuring access to safe and secure energy for the United States. According to the U.S. Energy Information Administration (EIA), production in the Gulf of Mexico accounts for 15% of total crude and 5% of total natural gas from the United States. With the ongoing national efforts supporting decarbonization and renewable resources, these structures are being considered for reuse; however, many of these structures have been operating for close to or past their design life, while others are at risk of attrition before return on investment. To better understand the potential for reuse or life extension opportunities, an assessment of the infrastructure integrity is critical to inform safe decision making. Assessing structural integrity, AIIM provides key insights that inform infrastructure use and reuse, as well as risk prevention planning, in support of stakeholders including regulators, researchers, and industry.
