BOP Reliability - Challenges
• Challenges:
Optimize BOP Maintenance Items
through in-depth analysis of failure
data to:
- Increase safety and BOP Uptime
- Perform the right maintenance at
the right time
- Optimize spare parts across a fleet
of drilling rigs
- Mature maintenance organization to
Preventive and Risk Based Approach
to leverage failure data collection to
generate value.

BOP Reliability - Element of Risk Based Approach
• Risk
• Probability of Failure
• Asset type
• Manufacturer asset
• Condition of the asset
• Uncertainty in the asset condition
• Consequence of Failure
• Non Productive Time
• Loss of function
• Safety impact
• Environmental impact
• Reputation impact
• Costs emergency maintenance

BOP Reliability - Optimizing the maintenance function
• Set Reliability Targets for the next section
of the drilling program to make the best
decision on:
• Inspection Items
• Maintenance priorities and planning
• Overall cost
Such Performance based optimization
tools allow for transparent discussions
between the different company
stakeholders committed to improve BOP
uptime.

BOP Reliability - Data
Probalistic Methologies are used extensively in Oil and Gas companies,
especially when it comes to risk management or areas like portfolio
management.
While the general feeling in Drilling is that there is not enough data to
get started, you would be surprised on how much it is possible to extract
from the data you already have. Some of our clients are already
benefitting from our analyses.
In addition, Lloyd’s Register is clearly committed to Data Analysis and has
a number of research projects, including some led by our Foundation,
around Big Data and Data Mining to understand the best possible ways
to extract maximum value from data sets.
