“…One of the biggest risks for operational safety is an uncontrolled influx of oil and gas from the formation to the surface, which means a blowout. In order to ensure the control and safety of the well, offshore rigs are equipped with a Blowout Preventer (BOP) that makes possible the controlling of hydrostatic pressure and allowing the well to shut in case of unbalanced situation (difference between the pressure of the mud column and the well pressure) (Martins et al, 2015). As Sattler mentioned (2013, p. 1), "BOP equipment and systems have been understood as one of the most safety critical of all rig equipment.…”

The sensibility originated by the Blowout Preventer (BOP) theme, due to all attention gathered after the Macondo event, established a high level of requirements from regulatory agencies, clients and Drilling Contractors themselves. Based on these pillars, the concept of reliability has been constantly applied in the oil industry, especially in the Well Safety and Control System, where it is extremely important for the equipment to be reliable and operational when required. In parallel, the Condition Based Maintenance (CBM) and Prognostic Health Management (PHM) concepts, widely used in critical industries, which require high reliability levels, are being pointed out as the future for the BOP system management. Within this context, the purpose of this paper is to review the literature on Condition Based Maintenance and Prognostic Health Management, integrated with reliability concepts, and to enable them to be applied in the BOP health management. The paper identifies different concepts needed to support the main theme and, through research and selection criteria, it brings together a set of publications to obtain consistent theoretical framework. This research outlines important techniques used in high reliability industries and the way they can be applied on the BOP system and it also provides many useful references and case studies to assist on further development works in terms of well control and operational safety.

Subsea blowout preventer (SBOP) reliability is a major challenge in Deepwater Drilling & Completion operations, accounting for one of the major equipment failures and Non-Productive Time (NPT) costs yearly. This paper focuses on SBOP technological advancement since the Deepwater Horizon/Macondo incident in 2010, with additional emphasis on reliability, equipment condition monitoring and statistical root cause analysis. After finishing a deepwater well, the SBOP must undergo maintenance, repair if needed and pressure testing before being deployed on the next well. The rig owner is under great pressure to complete this turn-around to avoid waiting time. On an average, in-between wells, rig contractor took approximately 2.6 days extra time (NPT) waiting after completing top hole to get ready to deploy SBOP during 2019-20 exploration and appraisal campaigns. This can be critical during development campaigns where number of rig moves are involved quickly or in cases where top holes are batch drilled the waiting time for SBOP readiness can be as high as 7-8 days per well. Some operators are collaborating with drilling contractors in number of ways to arrange for a second fully assembled and (offline) pressure tested SBOP to be available on the rig (Dual SBOP); deployment of additional trained subsea engineers for performing maintenance/repair. SBOP pressure-testing time can also be drastically reduced by using comparative pressure-testing software to eliminate human error and accelerate pressure testing. Furthermore, leak detection time can be eliminated by installing sensors, and real-time test monitoring providing increased reliability with the additional advantages that conditional monitoring can be enhanced with the same digital sensors. SBOP dashboard that simplifies existing diagnosis and allow remote monitoring of the subsea SBOP control system will improve communication of SBOP health also serve common platform across rig fleets that allow standardization of SBOP diagnostic data and aids in operational decision making Ensuring additional SBOP redundancy especially while operating Emergency Disconnect System (EDS) available through Remotely Operated Vehicle (ROV) control panel or acoustic system. In addition, it is mandatory for the SBOP to have Autoshear and Deadman systems to be able to shut in the well in case of an emergency. Furthermore, technological workshop with several major service vendors have being held to ascertain current advances like Multifunctional profile, Accumulator recharged by ROV, ROV DP system, An Auxiliary Accumulator System and upgraded Acoustic System. In the end, the development of new technologies applied for the SBOP targets the overall cost optimization of the well lifecycle but also assure SBOP functionality. This paper is intended to provide considerations for operators in developing their future campaigns to frame scope of work for SBOP and rig contracting strategy.
