2 Agenda Project summary Product demonstration Conclusion

3 Who we are Lloyd s Register A leading class society with more than 250 years of focusing on safety A not for profit, whose mission is to protect life and the environment 40 years of risk management engineering ModuSpec A global leading independent expert in the offshore upstream drilling industry We have currently inspected approximately 80% of the rigs around the world

4 Who we are Scandpower 40 years of risk management engineering 50% of the Nuclear power plants worldwide 80% + of the Nuclear power plants in Europe WEST Engineering Services Recently integrated into Lloyd s Register Combined, ModuSpec and WEST have serviced approximately 100% of the world s deep water drilling fleet

5 Well known facts 1. Blow Out Preventers Are critical to the success of any drilling operation Are the ultimate line of defense in protecting life and the environment 2. Costly Downtime Running, retrieving and re-running Repairing and testing Daily operational costs of up to $1.2M per day 3. Retrieving BOP from the Wellhead unnecessarily Setting packers and cement plugs Requires displacement of mud column Involves inherent risk to life and the environment

6 Industry challenges The industry has encountered many challenges with being able to objectively assess the risk and determine whether to continue with, or suspend, drilling operations. Transparent decision making by stakeholders which is acceptable to both senior management and regulatory bodies Being able to quickly and accurately determine whether to Pull or Not to Pull the BOP Safety of personnel, the environment and equipment Inconsistent decision making

7 Our solution The Risk Model assesses risk in an unbiased fashion and uses regulations, specifications and operational procedures to accomplish this successfully. Renders accurate logical decisions Turns days of NPT into hours Provides transparency to stakeholders and regulatory bodies alike The Pull or No Pull status is determined in moments Limits personnel risk by limiting exposure unnecessarily Gives consistent, objective decisions 100% of the time with a historical record of all decisions

8 Criteria for a Risk Model Independent third-party Subject Matter Experts (SME) SME s with explicit knowledge for a specific system Proven Risk Management software in a safety critical industry Experienced Risk Management Engineer SME Experienced Software Engineers Developers To develop a BOP specific risk model Failure Mode Effect Analysis (FMEA) Building logic block diagrams Fault trees, more than 400 individual trees Systems/subsystem/components 630 components and over 1,065 failure modes were modeled Approximately 4,000 man hours to develop the product Use of a Joint Industry Panel for vetting outcomes

9 Current Status We have delivered and successfully trained on the first BOP Risk Model and we are convinced that if this type of approach is embraced it will dramatically improve and streamline the decision making process and ultimately it will save: Time Money Equipment The environment Most importantly protecting and saving lives

10 Summary of Industry Advantages 1. Streamline communications between all parties involved 2. Validate or support life-cycle counts and reliability & predictability 3. Develop more robust maintenance programs 4. Emergency response planning 5. Can aid BSEE in rapid and reliable system evaluations and assist in determining operational stability. 6. Built by independent subject matter experts increasing objectivity 7. Based upon current day rates if approximately 1.25 days of NPT eliminated Return on investment (ROI) will be realized

11 Future developments Web-based software design Mitigating solutions Well program variables. Real time monitoring Industry benefits continue to grow

12 Risk Model Color Coding Low Risk Green means the level of redundancy is more than the minimum required. Normal well operations may be continued out with no restrictions. Moderate Risk Yellow means that the redundancy is above the minimum required however certain well operations may need to be completed and time restrictions may need to be imposed.

13 Risk Model Color Coding High Risk Orange means the BOP is operating with a single point of failure on a critical function, you will suspend drilling operations; complete a risk assessment of the failure taking into account the actual risk in the drilling program and other circumstances such as the risk of the decision to pull. Orange always means stop - evaluate risk - decide record communicate - agree Unacceptable Risk RED means the critical functions cannot be operated, the BOP is under the minimum requirements, the risk involved in continuing are too high to allow operations to continue before solving the problem. The BOP must be pulled and repaired prior to continuing

17 DEMONSTRATION

18 Case Study 1: Multiply Leaks in LMRP/BOP Simultaneously An offshore drilling rig developed several simultaneous leaks most of the leaks by themselves were minor issues, however the sum total made some personnel uneasy, which left some them undecided on continuing with operations, pull the LMRP, or to pull the entire BOP stack. Over the next few days, a number of teleconferences were organized between the drilling manager, his staff and shore-based experts to discuss issues and to clearly identify the root cause. 1. Leak on the lower annular open function 2. Leak on mud boost valve open function from blue pod 3. Leak on the pre-set POD supply regulator which was reduced to an insignificant level by tightening some nuts with the ROV therefore controlling it. 4. Leak on surge-stripping accumulator bottle on upper annular which rendered the upper Annular inoperative Lower annular closed fine which allowed for well control Lower annular open - leaked fluid when attempting to open but could be controlled by closing the valve. Worst case scenario was if the Lower Annular open lost all pressure and did not open due to loss of memory in the rubber, then it could be pressurized open with the ROV. In this particular case it was decided to leave the lower annular open in block until it was needed. The result of definitively identifying the problem was they were able to avert pulling the stack

19 In Conclusion We have briefly summarized the development of the BOP risk model time and effort that it took to develop Companies that were involved in the development & experience in their respective industries The many advantages of utilizing product this type We have demonstrated the ease of utilization of the tool The thoroughness of the tool That tool provides everything the industry told us that should Our desire, is that you leave this presentation with a better understanding of how our risk model makes it s decisions based upon regulations specifications and logic. As well as how much this could positively impact the oil and gas Industry
