Subsea Well Incident Intervention Service |

Summary SWRP planned an integrated intervention system for international use System includes capping stacks and subsea dispersant hardware SWRP and Oil Spill Response Ltd are collaborating to make the equipment available to industry Industry can access equipment via membership of OSRL and a supplementary agreement First equipment ready for response from the end of 2012 Equipment stored in four international locations from

The challenge in 2010 Industry must be prepared to respond in the event of a future serious subsea well control incident Industry must demonstrate its ability to operate safely and responsibly International response capabilities are needed State-of-the-art response tools must be available 3

The industry working together *GIRG = Global Industry Response Group PREVENTION Better capabilities and practice in well engineering design and well operations management INTERVENTION Improved capping response in the event of an incident and to study further the need for – and feasibility of – global containment solutions RESPONSE Effective and fit-for-purpose oil spill response preparedness and capability Governments, regulators, NOIA, OSROs and industry initiatives PREVENTION OGP’s Wells Expert Committee 30 members PREVENTION OGP’s Wells Expert Committee 30 members OIL SPILL RESPONSE Joint Industry Project OIL SPILL RESPONSE Joint Industry Project INTERVENTION Subsea Well Response Project INTERVENTION Subsea Well Response Project

Started April 2011 Nine leading oil and gas companies Not-for-profit joint initiative Working to enhance the industry’s capabilities to respond to an international subsea well control incident Formed on the recommendation of OGP’s Global Industry Response Group (GIRG) 5 SWRP’s guiding principles: 1.Prevention is paramount 2.Working with regulators 3.Enhancing industry response capabilities 4.Rapid reaction on an international scale

SWRP’s objectives 6 Design a capping toolbox with a range of equipment to allow wells to be shut in Design additional hardware for the subsea injection of dispersant Assess and implement deployment option International response Faster reaction Reduced environmental impact Further assess the need for and feasibility of global containment solutions

Set to deliver an Integrated subsea intervention system Available for the majority of international subsea oil wells Designed for subsea use up to 3000m water depth Transportable by sea and/or air Ready for use from end of 2012 Stored in four international locations from 2013: Norway, Brazil, South Africa, Singapore Manufactured by Trendsetter Engineering and Oceaneering 7 Integrated Intervention system includes: Four capping stack toolboxes Two subsea dispersant hardware kits Integrated Intervention system includes: Four capping stack toolboxes Two subsea dispersant hardware kits

Capping stacks

Standardised capping platform 13 Connection kit

Standardised capping systems 14 Dual 18 ¾’’ 15k Rams on Main Bore Dual 7 1 / 16 ’’ 10k Gate Valves on Main Bore Common 15k System The integrated intervention system includes four capping stack toolboxes: 2 x full bore 15k capping stacks 2 x reduced bore 10k capping stacks

Independently verified quality QA/QC audit evaluations ongoing DNV engagement in progress: – Technical Verification of the Capping Toolbox at component and system level, following DNV OSS 300 for Risk-Based Verification – Qualification of the Capping Toolbox at component and system level, according to DNV RP A203 for Qualification of New Technology (no existing international standards or specifications for Capping Stacks) – To result in DNV Certificate of Fitness for Service of the Capping Toolbox

Subsea Dispersant Toolkit

Subsea dispersant equipment Subsea application of dispersant at a wellhead is an integral part of capping operations: Creates safer surface working conditions for response personnel Enhances the degradation of the oil Subsea dispersant hardware kits include: Tools for site surveys Debris clearing equipment Flying leads, distribution manifold and dispersant wands High, high volume accumulators OSRL holds strategically located stocks of dispersant (NB not included with system subscription) DEBRIS CLEARANCE BOP INTERVENTION DISPERSANT SYSTEM

Dispersant Chemical 18

Subsea dispersant chemical OSRL will hold strategically located global dispersant stockpiles, access to which is subject to separate and additional arrangements (NB! not included within the intervention system subscription) OSRL Dispersant Stockpile provides Access to 5000 tonnes (1.3 million gallons or barrels) of Chemical Dispersant 19

Containment capability Containment concept identified and deemed technically feasible based on available vessels (Vessels of Opportunity) 20 Further work to define current regional containment capability
