WUT, a wholly-owned subsidiary of HMM opened at Tacoma in 1999 operating an 80-acre terminal. Located on the 51 foot (15.2 m) deep Blair Waterway, WUT was the first major new container terminal development on the upper Blair following the removal of the Blair Bridge in 1997.
At the time it was the largest new terminal construction project in Port of Tacoma history with Hyundai and the Port partnering to invest a total of US$100m in the new two-berth terminal and on-dock intermodal rail yard.
Over the years WUT has been expanded to 102 acres and is now equipped with six quay cranes of which two new Super post-Panamax units arrived early this year. By mid-2011 the Port will expand the berth 600 feet (183 m) to a total of 1,600 feet (488 m).
