摘要： Resident Autonomous Underwater Vehicles (AUVs) reduce the associated vessel days and Green House Gas (GHG) emissions of offshore operations. Hosted subsea, resident AUVs would provide improved asset integrity through early identification of integrity issues and increased availability for inspection and intervention. Developers offer customized solutions for docking, power and communication. While customized stations offer bespoke advantages, each installation requires significant cost and design effort for integration into a Subsea Production System (SPS). This is a barrier to adoption. DeepStar?, an operator-funded Research & Development joint industry consortium, sanctioned several programs on accelerating the industry to a unified set of standards and operating practices for the integration and utilization of field resident AUVs within offshore fields. DeepStar CTR: 18302 - Standardization of AUV Docking, was focused on harmonizing existing AUV docking stations concepts to enable implementation at scale. As part of this project, existing information was gathered and critically reviewed a to highlight discrepancies and propose recommendations to API 17H to achieve alignment among other standards and the industry. There are several standards which relate to AUV docking station interface design and were the original foundation documents used in this study: API 17H, DeepStar CTR 11304, and ongoing work from SWiG. The team defined the project framework including the attribute definitions to be used for comparison and the classification of the information. API 17H 3rd Edition was used as the baseline standard. Therefore, attributes were classified 'in agreeance' or 'discrepancy'. A second level of classification was also attributed to comparisons which were 'Numerical' or 'Qualitative'. The project team had to agree on the credible sources of information to be input into this assessment. The Subsea Wireless Group (SWiG) a Joint Industry Project (JIP) dedicated to developing standards for subsea wireless communications was identified early as a contributor. The SWiG JIP were developing the first industry standard defining the power and communications requirements for inductively recharging an AUV at a subsea docking station. Other contributors included leading resident AUV developers. Their feedback had to be carefully managed to avoid conflicts of intellectual property and competitive advantage. Equinor was also a key contributor due to their development of the UID? Subsea Docking Station. From the analysis performed within this project, several gaps and recommendations were identified to be incorporated within the next revision of API 17H. Attributes where API 17H deviates from DeepStar have supported reasoning. For the most part, these discrepancies have been marked as "Keep API as is". Due to API 17H 3rd Edition having minimal requirements for power and data transfer, a significant percent of SWiG input was considered as additional attributes.
