1 Escape, Evacuation and Rescue of People (EER) Morten Mejlænder-Larsen

2 History Norway has North Sea offshore experience, while Russia has Arctic operational experience. The Barents Sea represents new opportunities and new challenges for both countries. Safe oil and gas operations are a common interest of both countries. Updated and harmonized industrial safety standards facilitates safety, cooperation, and cross-border activities. was established as a jointindustry project for this objective. In This was a Russian- Norwegian project, since 2009 it has become an international industry cooperation project. 2

10 Examples of Terminology Differences 10

11 The Barents sea The major morphometric characteristics of the Barents Sea are as follows: Area: 1,424,000 km2 Water volume: 316,000 km3 Average depth: 222 m Deepest depth: 600 m Is never completely ice covered. During March to April, sea ice usually covers only 55 % to 60 % of the surface area. The ice is a combination of multi-year ice >~ 3 m thick, first year ice >~ 1.5 m thick and icebergs. 11

12 Risk Identification for the Barents Sea Major EER risks which were identified include the following: Traditional EER methods may not be appropriate for most of the year The full range of ice conditions, including icebergs and sea ice, combined with cold weather, wind and other weather conditions which may be encountered; The logistics systems that may be available to support any required evacuation from the structure or vessel, including the presence of standby vessels; The long distances from the potential emergency site to the support bases and other facilities; The shortage of duly equipped support vessels that may be called on for assistance, with regards to their maneuvering and station-keeping abilities in ice; 12

13 Risk Identification for the Barents Sea Major EER risks which were identified include the following: The accumulation of ice on external surfaces and its effect on equipment operation; The limited amount of time that is available to react to a particular emergency situation; The effect of cold temperatures on human physiology and psychology, equipment, materials and supplies; The lack of experienced personnel and training facilities for the specific evacuation systems which have been proposed for the Barents Sea; The effect of the polar night, with extended periods of darkness, on personnel activities in Arctic conditions; Difficulties caused by communication due to magnetic conditions and high latitude, lack of satellite coverage and language differences; The possible lack of qualified medical help. 13

14 EER Topics covered by standards 14

15 Key Standards and Main Remarks ISO19906:2010 Petroleum and natural gas industries Arctic offshore structures (Chapter 18 and Appendix A18) The standard does not apply to specialized equipment or vessels associated with Arctic and cold regions offshore operations except insofar as is necessary for the structure to sustain the actions imposed by the installation and operation of EER equipment. ISO15544:2010 Petroleum and natural gas industries - Offshore production installations - Requirements and guidelines for emergency response The standard does not follow latest best practice and does not align with ISO19906, which it needs to do. However, the two standards are complementary and it is therefore a relevant document that should be referred to as part of step 4 of the performance standard process. NORSOK Z-013:2010 Risk and emergency preparedness analysis The standard is generic and can be used for the Barents Sea; however it does not identify the governing environmental conditions. The standard should be aligned with ISO19906 on guidance for risk assessment of EER system in Arctic climates. This standard provides a systematic approach to risk and emergency preparedness analysis. ISO31000 and ISO17776 are normative references in Norsok Z-013, which are agreed apply to Barents Sea EER system risk management process. NORSOK S-001:2008 Technical safety The requirements of the standard can be applicable to EER systems in the Barents Sea; however it should be evaluated by following the performance standards process proposed by the work group. 15

21 Escape, Evacuation and Rescue of People (EER) Conclusion Insufficient recommendations are stipulated by ISO for the selection of a proper secondary evacuation method No universal single secondary evacuation method is currently available that is suitable for evacuating offshore personnel under the full range of hazards that may be encountered in the Barents Sea Recommendations Use performance standards based on the actual risks for each location and installation configuration. 21
