IOGP/IADC BOP Reliability Database Mark Siegmund Chairman: RAPID - PowerPoint PPT Presentation

IOGP/IADC BOP Reliability Database Mark Siegmund Chairman: RAPID – S53 Oversight Committee IADC DEC Technology Forum

RAPID-S53 Overview • Online subsea BOP performance reporting database developed by group of seven offshore drilling contractors became operational in 2015. • Database combined with IOGP/IADC efforts, now in third iteration of Joint Industry Project with 14 contractors, 12 operators, and 3 OEMs. • Latest phase branded as RAPID-S53 (Reliability & Performance Information Database for Standard 53 well control equipment). • Over 6000 event reports now in database. • 700+ users from 29 participating companies accessing database • Management & organizational support provided by IADC as Project Coordinator.

BOP Event Cause Designations When Root Cause is known : • Design issue • Documentation error • Maintenance error • Procedural error • QA/QC manufacturing • Wear and tear When Root Cause is not known: • RCFA required ( always used when there is a loss of wellbore integrity) • Assessment pending ( e.g. used in the case where stack is still subsea) IADC DEC Technology Forum

A total of 2040 events were 1475 Not In reported by JIP members in Operation 2017. Events 565 In Of these, 1475 were Operation discovered with the BOP Events Stack ‘Not In Operation’. 22 Stack Pull Events This reflects the very positive fact that the bulk of events occurred while 2 Loss of equipment was being Wellbore inspected, maintained and Integrity Events tested prior to being put into service.

Initiatives in Development • Applying cycle count data to aid in trend analysis and reliability prediction. • Currently collating field estimates of hours in service for components where cycle count is more appropriate and cycle counts are not available. This will be replaced by estimated cycle counts for the applicable components. • When actual cycle count is not known, an algorithm will be used to estimate cycle count using date equipment was put in service and the date of the event. • The goal is to accumulate enough experience data to eventually predict MTBF for certain components. IADC DEC Technology Forum

Benefits realized by participants • Monthly event review by Technical Reference Group provides valuable opportunity to share information on events experienced. • Common issues on similar equipment identified. • Increased understanding by OEMs of problem areas needing rectification. • Improved procedures for hoses & fittings reduced leaks and unplanned stack pulls. • Refined RCFA process. • Potential problems not previously seen can be anticipated. • Increased efforts to improve product design for SPM valves, etc. IADC DEC Technology Forum

Working with Regulators to Support Industry Compliance • Modifications made to database facilitate Failure data reporting form failure reporting by operators and contractors to assist in compliance with the BSEE Well Data collection and failure Control Rule. analysis process • Operators and OEMs both receive failure reports. • Agreement with BSEE that reports can be forwarded directly to Bureau of Transportation Statistics (BTS) - data repository for BSEE. • Data reported directly to BTS protected by the Confidential Information Protection and Statistical Efficiency Act (CIPSEA). • Now working on data conduit to allow Operators to transmit reports directly to BTS.

Continuous Improvement As increased data continues to provide new learnings, these are shared for the benefit of all participants. In addition, A number of specific topcs have already been shared with the public: • Regulator Valve Improvement Initiative • Shuttle Valve Selection for ROV Circuits • SPM Valve Spool Poppet Identification • Deadman/Autoshear Timing Circuits • Improper Subsea Control Valve Design Aspects www.RAPID4S53.com IADC DEC Technology Forum
