Special Considerations

AEB-16-01 Pyramid Creek

Nearshore waters in the general areaof:

Lat. 53º 51.3 NLon. 166º34.3 W

Free-oil Recovery ProtectedWater

Maximize free-oil recovery inthe offshore & nearshoreenvironment of Pyramid Creekdepending on spill location andtrajectory.

Deploy free-oil recovery strike teamsupwind and up current of PyramidCreek.

Use aerial surveillance to locateincoming slicks.

Deploy multiple free-oil recoverystrike teams as required to maximizeinterception of oil before it impactssensitive areas.

Vessel platform. Via marinewaters

Divert and Collect

Divert oil to shore-sidecollection in the location nearPyramid Creek

Deploy anchors and boom withskiffs (class 6).

Place protected-water boom in atproper angle to divert incoming oil tothe collection site. Use the dockingfacilities as an anchor point

AEB-16-04 Obernoi PointLat. 53º 51.21 NLon. 165º34.05 W

Deflection

Deflect oil away from theWaterfowl concentration areas inCaptains Bay by Obernoi Pointto free-oil recovery.

Deploy boom and anchor systemwith skiffs (class 6).

Place three 500 ft. boom sections in acascaded pattern to deflect oil to freeoil recovery efforts. Adjust the angleand direction to accommodate tidaland sea conditions and direction ofincoming oil.

Tend throughout the tide.
