Panel discussion: One Gulf - Drilling Offshore Cuba
The Evolution Deepwater Oil Drilling Safety Regulation in Cuba: Lessons learned
• Before Yamagua Well (2002 – 2004)• After Yamagua Well (2005 – 2010)• After Macondo (2010 - present time)
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
Before Yamagua Well (2002 – 2003)The preparatory stage
Mature regulatory regimes
Self-regulationPrescriptive
• What is the challenge?• What regulatory strategy
to adopt?• How to make it work?
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
The Big Challenge:“To protect people and the environment by preventing major
(organizational) accidents from occurring” (i.e from events that occur 1/decades!!!)
Safety Case approach to Regulation: UK Safety Case Regulations (SCR) 1992
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
Type of regulatory strategy
Influence on Safety Culture
Prescriptive Poor
Outcome-based Regular
Process-based Good
The Safety Case regime
• Major Accident Hazards (MAHs) are identified
• Risks have been evaluated and measures have been taken to reduce the risks levels to ALARP.
• There is an adequate SMS for process safety/integrity
• Adequate arrangements exist for audit of the SMS
• Compliance with national/international regulations
The Operator must demonstrate to ORASEN, that:

Yamagua -1 Exploratory Drilling2004
• Regulatory Guidance issued by ORASEN “Guidelines forpreparation of Risk Evaluation Report (RER) for Offshoreoil drilling facilities” – 2002 (now superseded).
• Environmental Licence issued by ORASEN for deepwaterdrilling:
Risk Evaluation Report (RER)Safety Evaluation Report (SER)Licence conditions for deepwater drilling operationsRegulatory inspection to the drilling facility

After Yamagua – 1: 2005-2010Adoption of international best practices and modernization
of Facility Safety Cases
2009
2004
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
Strengthening the Safety Case regime for major hazard facilities in Cuba - 2009
• CITMA Resolution 132/2009 “Rules for EnvironmentalImpact Assessment Process”
Updates previous rules and introduces Safety Cases for MajorHazard Facilities in support of Environmental Licenceapplications for all MHFs for the commencing of operation.
• ORASEN Resolution 31/2009 “Guidance for preparation of Safety Cases for drilling facilities for offshore oil and gas exploratory wells”
Establishes new requirements for Safety Cases according toIADC HSE Case guidelines (version 3.2).
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
“Modernization” of Safety Cases
• ORASEN “encourages” the use of Bow-Tie RiskManagement Methodology as part of the SafetyCase process:
Increasing the value of the Safety Case for SC“owners” - i.e managers and workers.Ensuring SC remains a “Living document”.Allowing better regulatory oversight.
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
“Modern” Safety Cases reviewed by ORASEN
• Bow –Ties for all MAHs
• SOOB Matrix (MOPO)
• Safety Critical Elements (SCEs)
• Performance Standards (PS)
IADC Environmental Conference and Exhibition, Trinidad and Tobago 12-13 May, 2011
• CITMA Resolution 73/2010 “The Safety Case Addendum”Introduces the Safety Case Addendum for Well Integrity issues;following US Well Construction Interfacing Document (WCID)recommendations.
• CITMA resolution (scheduled for 2011): “Safety CaseRegulation for Major Hazard Facilities” which avoidspiecemeal implementation.
Delineates all the features of the Safety Case regulatory regime“from cradle to grave”.
After Macondo: 2010-?Well Integrity, Emergency Response, Safety Culture Oversight

A consistent, sound and state-of-the-art regulatory framework for deepwater drilling
safety
• One Gulf means for us:– One COMMON interest: To protect people and
the environment while conducting deepwaterdrilling operations in the GOM.
– One COMMON challenge: To prevent majoraccidents from occurring and limiting theirconsequences should they occur.
– One COMMON solution: To set up a consistent,sound and state of the art regulatory frameworkaddressing Safety Culture aspects.
