PROJECT SPOTLIGHT
Drift River Erosion Control
Located at the base of Mt. Redoubt, an
active volcano, Drift River is home to
seven 10-million-gallon fuel tanks. The
2009 eruption of Mt. Redoubt unleashed
flooding five times greater than the flow
of the Mississippi River; the tank farm
nearly washed away. In 2012, Hilcorp
Alaska commissioned a design-build
project to better protect its assets against
high-impact flooding. The solution was
a hybrid earthen dike and sheet pile wall
stretching 3,000 lineal feet. Barges brought
equipment and materials into Cook Inlet
during high tide, dropping anchor as the
tide receded. Once the tide was out, the
crew created a tidal mudflat road to unload
and mobilize four million pounds of steel
and equipment.
In just five months, STG took the
project from design to procurement to
completion—on time, on budget, and with
zero change orders.
