API RP 16AS June 2017 Recommended Practice for Integration of Subsea BOP Equipment Systems for Drilling Wells – Update

GOAL: Develop a schematic of the systems in the 16AS scope to identify other specifications that already sufficiently cover sections 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

First Meeting Summary: Which API documents will be included or not included? Stay with Drilling, not CWO operations at this point Capping Stack interface must be considered Start generally with S53 scope and look at delineations Included Not Include Interface 16A, 16C, 16D, 16F, 16Q, Q1, MPD, 7K, 8C, S53, S64 16B, 16 ST, RP 59 17W, 17G 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

First Meeting Summary: Acknowledged that some things can’t be done until systems are integrated in the field Should cathodic protection for subsea be included? Should bolting be included? Should stainless in subsea application and coatings be included? What else is missing? 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

First Meeting Notes: Reviewed the S53 Scope Do we target BOP Stack first and then expand to the rest of the system? WG agreed yes, otherwise the scope will become broad and difficult to manage The workgroup agreed to start at Wellhead Connector, “build stack” conceptually, and see what the gaps are for the system Given the expertise in the room, it was decided to begin with a subsea stack 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org

Path Forward: Perform Gap Analysis for a Subsea Stack from the wellhead up This will be put into Excel Spreadsheet which identifies API document which applies and develop a gap matrix Next meeting: Wednesday, July 12, 2017 1220 L Street, NW • Washington, DC 20005-4070 • www.api.org
