5 Offshore Leak Detection Leak detection a challenge facing the industry Over the last few years, following several oil releases, there has been an increasing focus from both operators and authorities on the environmental impact related to offshore oil- and gas activities. Leak detection methods and techniques have been available in the market for several years but there are still gaps to be closed concerning the design, engineering, commissioning and operation of these systems to ensure proper performance.

6 Common challenges with the leak detection techniques Number of false alarms Both false positives and false negatives are creating complications and challenges. Sensitivity vs. indications While high sensitivity could be beneficial, it requires significant resources. Reliability and robustness Stable coverage, reliable indications, expected durability and required maintenance. 6

7 Challenges for the operators Performance and requirements What can and should be detected? Is it possible to define pollution of significance or acute leaks? Will authorities agree? BAT framework Use an established methodology with concrete parameters that should be considered? Testing the techniques How should the techniques be tested and compared? Which parameters should be emphasized? Remote sensing plans Framework for documents describing technologies used on the relevant field, routines, weaknesses etc.

8 Further focus for the industry System Focusing further on finding techniques that complete and complement each other and that are able to interact and connect. Innovation Operators need to utilize the new solutions in order to bring the field forward. Field testing and user feedback are vital elements. Cooperation Between suppliers of the techniques in order to connect technologies. Communication between operators can bring forward common challenges and experiences.

9 Joint Industry Project - Offshore Leak Detection DNV GL and the Oil & Gas industry join forces to shape the future for offshore leak detection! The JIP has the ambition to develop an international recommended practice (RP) addressing the lifecycle phases of a typical offshore development project. This RP will replace DNV-RP-F302 Selection and Use of Subsea Leak Detection Systems from

12 Schedule Clarification meeting March 2013 Kick-off meeting December st steering committee meeting March nd steering committee meeting + Workshops May rd, 4th and 5th steering committee meeting September 2014 May 2015 Final Guideline May/ June

13 Regulations and requirements Applicable regulatory requirements for leak detection will be identified in the following countries: US, UK, Norway, EU, Australia and Brazil The functional, risk-based requirements, and the expectations for the leak detection system will be defined. 13

14 Operational experience and leak statistics Gathering of experience from operators of leak detection systems and update of leak detection installed base. This work package will require collaboration from the operating companies. Update on leak statistics (frequency, size, location etc.) based on data available to the project. 14

15 Technology mapping Subsea technology Topside technology Emerging technology Mass balance Copyright: ENI Norge AS 15

16 System design, integration and testing Gathering experiences from suppliers and integrators on: Installation and interfaces, and requirements and challenges. For testing, the ambition is to establish requirements for qualification testing, production testing, FAT testing, SIT and function test when in operation. 16

17 BAT and selection process Best Available Technique The objective for this activity of to perform a best available technique analyse for the leak detection systems. The outcome will be a suggested methodology for evaluating various techniques and choosing solutions that are most suitable for the relevant installations. This work package aims to define a specific BAT process for selection of leak detection systems. 17

18 Management processes Principles concerning comissioning and maintenance Evolve LD management and operation process Define procedures that can reduce the likelihood of false negative alarms and actions that can decrease false positives over time, incl. feedback to suppliers. Define interface between LD sensor and the LD system. Link to: emergency preparedness plan (e.g. activation of satellite imagery) integrity management and inspection methods environmental monitoring 18

19 Picture: ENI Norge AS Offshore Leak Detection Joint Industry Project We really want to see a development in these systems. Today, it is difficult to get a good system with a demonstrated track record that covers an entire field, both subsea and surface. To improve, there is a strong need for a common approach so that the operators and suppliers can jointly improve these systems. We also need to define what are reasonable specifications and requirements. It is equally important to consider how different technologies can be integrated into a system that is practical for the end user. 19 Arnljot Skogvang, Lundin-Norway AS
