M/V STRYKER Salvage• Casualty occurred at approximately 1130 on September14, 2010• Vessel reported that the wheelhouse partially separatedfrom the vessel due to structural failure. Stern resting onthe seafloor• 40 Miles West of Prudhoe Bay on the east side of theColville River Delta. N70°31’19”, W150°5’44”
M/V STRYKER Salvage• Owners engaged Global to respond immediately to affectsalvage of the vessel. Salvage Master mobilized fromPortland and salvage crew and equipment fromAnchorage.• Owners reported having engaged 2 shallow draft tugsand a crane barge to assist.• Salvage crew and gear arrived at and boarded thecasualty at 1700 September 16.
M/V STRYKER Salvage• Self Propelled barge constructed from 20 Flexifloatmodular barges• 140’ x 40’ with maximum draft of 7’• Twin 671 Detroit Diesel engines
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 vesseltogether at the break• Forward section badly wasted with no integrity
M/V STRYKER SalvageChallenges –Remote location with extremely volatile weather. Airfreight of gear and access to casualty weatherdependent.Floating resources were available but lacking incapability – i.e. Crane barge with no ability to moor.Casualty located very near Iñupiat village on the ColvilleRiver Delta – impact to subsistenceWildlife - Polar Bears
M/V STRYKER SalvagePositives –Access to all of the resources available in Deadhorse andPrudhoe Bay.Lodging and transportation at nearby base camp.Alaska Clean Seas for on water support and pollutionresponse.Excellent logistics support.Internet and telephone communications.
M/V CLIPPER ADVENTURER• 331’ vessel grounded on Friday, August 27, 2010 in a remotebay in northern Canada.• The location is exposed to strong weather fronts generatingsignificant wind and ocean swells.• A total of 13 double bottom tanks were breeched. The extentof the damage was from the fore peak to well aft of amidships.

M/V CLIPPER ADVENTURERChallenges –Onshore command centre at Yellowknife which is severalhundred miles from the location.Poor communications with satellite service unstable that farnorth.Logistically difficult due to the remoteness of the location withno “local” services to support the operation.Transportation to/from site was limited to float planes withmarginal fuel capacity for the distance travelled
M/V CLIPPER ADVENTURERAircraft landings on site was weather dependent. On occasionsthe weather would change after the aircraft was in flight.Unpredictable weather systems which may not be forecast byweather service.Inadequate support vessels / bollard pull available.No border custom clearance point in the Canadian Arctic whichmeant that equipment mob and demob were “challenging”.Limited season to work due to short arctic summers.
Arctic OperationsFuture Efforts are Necessary• Recognize that the Arctic marine environment will beaffected by International trade and vessel transits• Best engineering practices for new infrastructure• Pre-stage gear with applicable plans for mobilizationand cascading of equipment and resources• Cooperative efforts that combine available resourcesand technologies with Area Contingency Plans• Continued analysis of specific case projects• Continued assessment of various locations utilizingsubject matter experts coupled with local knowledge
Conclusions• The Arctic is unique with regard to area and responsecapabilities• New operations, exploration and development offerthe US and Canada an opportunity to engineer andplan for emergency response using newertechnologies and lessons learned elsewhereEmphasis should be given to Preventionto reduce the need for Response
