1 Cooperative benefits and challenges in building the necessary preparedness capacities Svein Olav Drangeid Head of HSSE, OMV NW Europe Member of BaSEC Steering Committee

3 Ensuring operational preparedness for exploration Metocean and ice Environment and oil spill preparedness Logistics and emergency response Mobile drilling units Health and working environment

4 Joint solutions

5 HSE risks can be managed Members share existing data and experience Increased knowledge based on new data

6 Physical environment comparable to the North Sea Currents, wind and waves similar to the North Sea Low risk of sea ice and ice bergs Low minimum air temperatures Polar lows, snow and icing needs attention

7 Good emergency preparedness is possible Long distance to shore Recommend new performance requirements Satellite coverage Winterization Health and working environment

8 Logistics and emergency response main findings Remoteness a key challenge for ensuring a robust level of emergency response Helicopter operations (transport and SAR) within 300 nm is feasible with existing helicopter technology The field resources (especially SBV) to be given an extensive role during operations and serving as an integral part of the emergency preparedness Winter operations acceptable, will require adequate winterization of equipment and focus on operational procedures A system for sea ice management and surveillance is needed in the most remote areas

9 Overall recommendations Proposed new DSHA s Helicopter accident into the sea en route Sea ice or ice berg on collision course with rig New performance recommendation Target should be to rescue personnel from lifeboats within 24 hours after lifeboats have been launched There shall be capacity to rescue personnel from sea within 8 minutes for man over board, after accident is detected Persons in the sea following helicopter ditch outside the safety zone. The helicopter passengers and crew shall be picked up from sea as soon as possible but within 4hrs.

10 Identification of actions to be evaluated EER operations evaluated Medical evacuation via SBV (hoist stretcher from rig to SBV) Downmanning/evacuation of rig personnel to SBV Man over board situations, with MOB-boat and/or FRDC. Rescue from sea after evacuation of the rig, by MOB boat, direct to SBV or helicopter. Rescue from lifeboats after evacuation, by MOB-boat or hoisting to helicopter Pick-up or escort of lifeboats by SBV Rescue from sea after helicopter accidents within the 500 m rig safety zone Rescue from sea after helicopter accidents en route to installation outside 500 m safety zone Additional topics discussed Safe transport Monitoring within and outside safety zone Handle defined emergency situations Rig operational safety systems Safely abandon well (interaction with MoDU) Well control measures (interaction with MoDU)

11 EER operation evaluated Medical evacuation via SBV (hoist stretcher from rig to SBV) Rig Consider two medics on the rig, in order to ensure that one of them can stay with patient onboard SBV Evaluate to include crane inspections as a part of the winterization manual. Ensure crane(s) is (are) operational in low temperature and icing conditions Competence/training Evaluate additional requirements to training for crane operators working in the Barents Sea, to reflect the extended use of personnel baskets in EER operations

12 EER operation evaluated Downmanning/evacuation of rig personnel to SBV Rig Winterized transfer capsules and proper storage Competence/training Clarify operational restrictions for crane operations with regards to visibility, e.g. in fog situations

13 EER operation evaluated Man over board situations, with MOB-boat and/or FRDC SBV Redundancy (in the form of additional MOB boats or helicopters) important with regards to whether a MOB boat should be launched, in order to ensure the safety of the MOB personnel Additional SBV MOB crew during remote operations in cold climate Extended competence and skills training of MOB crew

14 EER operation evaluated Rescue from sea after evacuation of the rig, by MOB boat, direct to SBV or helicopter SBV SBV/MOB boat equipped with AIS tracker system Training/Competence Evaluate extended training for self rescue during courses

15 EER operation evaluated Rescue from lifeboats after evacuation Lifeboats Issues associated with icing on lifeboats should be further investigated (icing on hatches, air intake, stability etc.) Ensure communication system between lifeboats and SBV/MOB SAR crew need to familiarize with relevant lifeboat types on current rig (e.g. inspections in field)

16 EER operation evaluated Pick-up or escort of lifeboats by SBV Lifeboats Clarify if towing of lifeboat by SBV is and option Clarify the fuel capacity for lifeboats

17 EER operation evaluated Rescue from sea after helicopter accidents within the 500 m rig safety zone SBV Redundancy (in the form of additional MOB boats or helicopters) in rescue systems in order to ensure the safety of the rescue personnel Limitations on number of passengers in helicopter transport flights if weather conditions not allow launching of MOB boat

18 EER operation evaluated Rescue from sea after helicopter accidents en route to installation outside 500 m safety zone Helicopter Increased frequency on helicopter flight tracking. Seconds will further improve the ability to locate the accident site AIS transmitter on helicopters The operator together with SAR crew must develop a plan for how they should respond and plan a rescue operation for different helicopter crash scenarios (with respect to distance from shore)

19 Operation evaluated Safe transport Equipment Additional thermal clothing required ("vams or similar) and to be defined as mandatory PPE PLB (AIS/121.5 VHF) on survival suits

20 EER operation evaluated Monitoring within and outside safety zone Operations Establish ice risk management plan, detection and monitoring, identify hazards and establish response procedures Evaluate use of measures on rig, SBV, fixed wing/helicopters for detection and monitoring

21 Operation evaluated Handle defined emergency situations Helicopter Evaluate new temporary helicopter base onshore for Barents Sea SE operations SBV SBV need to have dedicated landing area for crane transfer basket for personnel

22 Operation evaluated Rig operational safety systems Rig Winterization gap assessment according to season of operation to be carried out Winterization of safety barriers/safety systems SBV Winterization gap assessment of SBV and PSV, according to season of operation and use in emergency situations Operations Adapt activity level onboard according to operating conditions/environmental conditions and status on safety- and EER systems

23 Operation evaluated Safely abandon well Well control measures Operations Monitor BOP integrity with ROV if well has to be left for longer period during sea ice without temp or permanent P&A Ensure sufficient mud supply according to well conditions and logistical supply times Evaluation of logistics and mobilization plan for capping stack installation at well site location.
