- 13. 6,640 miles of coastline including islands - 33,904 miles of shoreline
- 16. Industries & Resources utilizing the Marine Environment in Alaska • Oil/Gas – Cook Inlet and Arctic operations • Mining – Red Dog, near shore Nome, SE Alaska • Timber – Southeast and south central • Fishing/Aquaculture – All coastal waters • Tourism – Primarily SE, south central and, lately, the Arctic • Cargo Vessels – Ships and barges hauling freight to and from Alaska • Vessels in Transit – Ships and barges transiting the Great Circle route pass through the Aleutians
- 17. Vessel Traffic North Pacific & Alaska One Day in April 2013
- 18. Nome Point Barrow Marine Exchange of Alaska Arctic Maritime Activity in 2012
- 22. M/V STRYKER Salvage • Casualty occurred at approximately 1130 on September 14, 2010 • Vessel reported that the wheelhouse partially separated from the vessel due to structural failure. Stern resting on the seafloor • 40 Miles West of Prudhoe Bay on the east side of the Colville River Delta. N70°31’19”, W150°5’44”
- 23. M/V STRYKER Salvage • Owners engaged Global to respond immediately to affect salvage of the vessel. Salvage Master mobilized from Portland and salvage crew and equipment from Anchorage. • Owners reported having engaged 2 shallow draft tugs and a crane barge to assist. • Salvage crew and gear arrived at and boarded the casualty at 1700 September 16.
- 25. M/V STRYKER Salvage • Self Propelled barge constructed from 20 Flexifloat modular barges • 140’ x 40’ with maximum draft of 7’ • Twin 671 Detroit Diesel engines
- 26. M/V STRYKER Salvage • Stern rests hard abottom in 14 feet of water • Bottom consists of thick, sticky mud • Heavily damaged pins marginally holding the vessel together at the break • Forward section badly wasted with no integrity
- 31. M/V STRYKER Salvage Challenges – Remote location with extremely volatile weather. Air freight of gear and access to casualty weather dependent. Floating resources were available but lacking in capability – i.e. Crane barge with no ability to moor. Casualty located very near Iñupiat village on the Colville River Delta – impact to subsistence Wildlife - Polar Bears
- 32. M/V STRYKER Salvage Positives – Access to all of the resources available in Deadhorse and Prudhoe Bay. Lodging and transportation at nearby base camp. Alaska Clean Seas for on water support and pollution response. Excellent logistics support. Internet and telephone communications.
- 34. M/V CLIPPER ADVENTURER • 331’ vessel grounded on Friday, August 27, 2010 in a remote bay in northern Canada. • The location is exposed to strong weather fronts generating significant wind and ocean swells. • A total of 13 double bottom tanks were breeched. The extent of the damage was from the fore peak to well aft of amidships.
- 35. M/V CLIPPER ADVENTURER CLIPPER ANDVENTURER
- 36. M/V CLIPPER ADVENTURER Casualty Command Post 380 Miles Safe Harbor 220 miles
- 38. M/V CLIPPER ADVENTURER Port Epworth Cambridge Bay
- 39. M/V CLIPPER ADVENTURER Challenges – Onshore command centre at Yellowknife which is several hundred miles from the location. Poor communications with satellite service unstable that far north. Logistically difficult due to the remoteness of the location with no “local” services to support the operation. Transportation to/from site was limited to float planes with marginal fuel capacity for the distance travelled
- 40. M/V CLIPPER ADVENTURER Aircraft landings on site was weather dependent. On occasions the weather would change after the aircraft was in flight. Unpredictable weather systems which may not be forecast by weather service. Inadequate support vessels / bollard pull available. No border custom clearance point in the Canadian Arctic which meant that equipment mob and demob were “challenging”. Limited season to work due to short arctic summers.
- 41. AIS Receiver Locations in Alaska
- 42. AIS Receiver Locations in Canada
- 43. Arctic Operations Future Efforts are Necessary • Recognize that the Arctic marine environment will be affected by International trade and vessel transits • Best engineering practices for new infrastructure • Pre-stage gear with applicable plans for mobilization and cascading of equipment and resources • Cooperative efforts that combine available resources and technologies with Area Contingency Plans • Continued analysis of specific case projects • Continued assessment of various locations utilizing subject matter experts coupled with local knowledge
- 44. Conclusions • The Arctic is unique with regard to area and response capabilities • New operations, exploration and development offer the US and Canada an opportunity to engineer and plan for emergency response using newer technologies and lessons learned elsewhere Emphasis should be given to Prevention to reduce the need for Response

- Speak to the crane issues
- Point out the break seam.
- A total of 4 tugs were used to refloat the vessel on Sept 14 and towed to Port Epworth for survey and repairs. Then on to Cambridge Bay on Sept 17 for redelivery.
