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.
