North Slope Docks For Alaska Clean Seas
AFC selected Robishaw Engineering’s Flexifloat sectional barges to provide their client with an off-the-shelf system that was easy to assembly in the field under challenging site conditions at an extremely remote project location and that could withstand the harsh environmental elements such as the frequent subzero temperatures within the Arctic Circle. ACS was replacing an existing barge at their West Dock Moorage Facility with two 140’ x 40’ x 5’ floating docks and adding a 140’ x 20’ x 5’ platform at a secondary site nearby. In addition to being used for mooring response vessels, these three platforms are designed to allow for fuel truck and other vehicular access by means of heavy-duty steel ramps and pedestrian gangways supplied by AFC.
A total of 30 Quadrafloats™ (40’ x 10’ x 5’) and 10 Duofloats™ (20’ x 10’ x 5’) were used to assemble the 14,000 ft2 of Series S-50 Flexifloat® equipment needed for the three dock systems. Robishaw Engineering also provided custom fendering and access ladders. Additionally, a high-quality, durable paint system was applied in anticipation of the severe marine environment and subzero temperatures. A non-skid additive was included in the deck coating. Deck hatches were added to some of the floats for potential ballasting.
