in January 2013, within weeks of the incident. The remit of this team was to conduct technical evaluations of failed bolts, to assess "fitness for service" of the manufactured bolts, and to identify gaps in industry standards, industry practices, or regulations.1 More importantly, the team was given the task "to evaluate the possibility of additional bolt failures and make recommendations to mitigate potential risks of future failures, either domestically or internationally."2 During its technical evaluation the team was made aware of "other offshore oil and gas failures related to bolts, studs, inserts and connectors, appearing to share similar contributing factors."3 It was at this point that BSEE tasked the QC-FIT "to evaluate whether the causes of these other failures were related and whether evidence existed of an industry-wide issue."4 The QC-FIT worked closely with Transocean, Chevron, and GE in evaluating the H4 failures on the Transocean Discoverer India.

The recommendations of the QC-FIT were the following: âĒ Improve various industry standards âĒ Initiate joint industry research initiatives to improve connector design and reliability âĒ Promote a comprehensive failure reporting system âĒ Develop regulations to ensure specific design standards are met. This QC-FIT effort was immediate response to indications that there may be some broad, industry-wide issues affecting the reliability of critical bolting in subsea service.

API RESPONSE Recognizing the potential consequences of these critical bolt failures, and especially the significance of the cluster failures, industry undertook failure analysis and root cause analysis, with participation by drilling contractors, OEMs, and operating companies. The oil and gas industry (mostly through the API)
