3 Ice Management Fleet Although it is planned to operate in the open water season a four vessel Ice Management fleet was put together for the eventuality of operating in ice throughout the anticipated season. A contingency contract for two additional conventional ice breakers is in place in case additional support is required for late season or demobilization operations. The ice management fleet is structured as follows 1. One Vessel at each theatre designated as the primary Ice Management Vessel 2. One vessel at each theatre designated as the secondary Ice Management Vessel and Anchor Handler October 31,

5 Primary Ice Management Vessel The primary IM Vessels conduct ice scouting missions far from the drilling unit confirming satellite imagery and assessing ice regimes with regard to the following 1. Hazard potential 2. Floe size 3. Stage of development 4. Set and drift 5. Manageability The primary IM Vessels provide the information and advise required to operate the ice management Alert System In addition these vessels are tasked with ROV and Dive operations as well as various science projects related to permitting October 31,

8 Secondary Ice Management Vessels The secondary Ice Management Vessels generally work close in to the drilling unit and are tasked with the following 1. Monitoring ice up drift of drilling units 2. Pushing, breaking or prop washing ice away from the drilling unit 3. Anchor handling and laying the mooring system for the drilling units. 4. Towing drilling units In addition the secondary IM Vessels can be sent on ice scouting missions as required October 31,

11 Emergency Resource The vessels Shell has brought to the arctic provide a resource which has not been previously available. In areas like the Gulf of Mexico, North Sea or other well developed areas of operation there are many resources from both government and private industry which may be called on in the event of emergency The Shell fleet provides a number of resources which are of use in these situations. 1. Four Ice Class vessels capable of ocean rescue and salvage 2. Three vessels and two drilling units with helicopter decks suitable for S-92 helicopters 3. Medical facilities throughout the fleet. October 31,

12 Emergency Response To Marine Emergency On Friday, December 3, 2010, Shell was asked to assist in the rescue of the bulk carrier M/V Golden Seas that had lost power north of Atka Island. The M/V Golden Seas was full of contaminant cargo and several hundred thousand gallons of bunker fuel oil. With 20 crew on board and limited power to its main engines, the Golden Seas was in danger of encountering rocks within hours. Shell was immediately contacted for possible use of the ice-class anchor handler Tor Viking II the same vessel Shell contracted to tow the Kulluk drilling unit to Dutch Harbor in the summer of The Tor Viking II was the only vessel in the region capable of assisting the M/V Golden Seas. On December 4, the Tor Viking II connected her tow wire to the M/V Golden Seas in 27-foot swells and began towing her to Broad Bay near Dutch Harbor. Both vessels safely arrived in on Tuesday, December 7. October 31,

13 Emergency Response Shell s close working relationship with the Coast Guard, federal agencies and DEC played a critical role in not only preventing an environmental catastrophe, but a human tragedy that became all too real to Alaskans two years ago when the M/V Selendang Ayu ran aground killing six crew members, tearing the freighter apart and forcing a Coast Guard helicopter into the water. Assisting with the rescue of the M/V Golden Seas is just one example of Shell s commitment to positively impacting the communities in which we work. October 31,

14 Tor Viking II / Golden Seas Ocean Rescue Tor Viking II with Golden Seas in tow arriving at Broad Bay anchorage after successful ocean rescue Shell SAR helicopters in the Canadian Arctic have responded to many emergency situations October 31,

15 Arctic Shipping Controls VTS type shipping control for Arctic regions Develop VTS type real time monitoring of all vessels working or transiting arctic regions Call in points Develop vessel ice class standard and arctic capabilities for vessels transiting ice bound regions Establish ice experience and or training criteria for ships Master and officers particularly tankers and vessels with high risk cargoes Ice breaker assistance at critical areas October 31,

16 Shell Arctic Marine System Four high function Ice Breaker Ice Class vessels with experienced Ice Masters and crew dedicated to Ice Management Ice Advisors experienced in arctic offshore drilling operations on all IM vessels, drilling units and tanker in addition to regular crew. Full time Ice and Weather department featuring 1. Weather forecast for dedicated location and or vessel 2. Daily ice analysis by highly experience ice experts 3. Accessing and up loading satellite imagery to the IM Vessels Enfotech IceNav system fitted on all ice management vessels and drilling units for display of satellite imagery and enhanced radar imaging. Vessel movement oversight and direction from head office with respect to weather, ice and operational issues. October 31,
