© Chevron 2013 Project Motivation  The development of industry standards for AUV interfaces, similar to the API standards for ROVs, will: –Lead to compatible system designs by AUV vendors and field hardware manufacturers, and –Enable safer, more efficient and cost effective operations of subsea fields. 5 Future capabilities and benefits of AUVs will be substantially enhanced through the use of standardized interfaces with subsea facilities

© Chevron 2013 Project Objectives  Project Objective: –Identify subsea interfaces which should be standardized for AUVs –Develop recommendations and preliminary drafts of interface standards –Submit to API SC17 6

© Chevron 2013 Preliminary List of AUV Interfaces for Standardization 7 Standardization Must Consider Both Greenfield and Brownfield Applications Docking Power / Battery Charging Communications / Data Transfer Mechanical Intervention

© Chevron 2013 Vision of Success  API Adoption of DeepStar Task Report as Input to a Recommended Practice.  Follow Outline for API RP 17H: –Scope –Normative References, Terms and Abbreviations –AUV Interface Philosophy –Design Performance –Design Considerations –AUV Interfaces and Subsea Systems –Operational Considerations –Indicator Systems –Materials –Documentation –AUV Interfaces –Informative Annexes  Deliver Draft RP Document to API SC17 in MS Word Format 8
