Port of Tacoma and the Northwest Seaport Alliance are celebrating progress on the reconfiguration of Husky Terminal to accommodate larger vessels.

The last of the 1,245 piles on Pier 4 was driven Wednesday afternoon, according to a release from the NWSA. The work on the Tacoma Tideflats facility is part of $250 million in terminal improvements that began in September 2016. Upgrades include strengthening and realigning a berth and adding eight new super-post-Panamax cranes capable of serving two 18,000-TEU container ships at the same time.

The new cranes, to be built by Shanghai Zhenhua Heavy Industry Co., Ltd. in China, will be capable of serving ultra-large container vessels with an outreach of 24 containers and a lift height of 165 feet above the pier deck.

The reconstructed berth at the northwest end of the Blair Waterway will also include conduit for future shore power to allow ships to plug into electricity while at dock.

Construction and the first four cranes are estimated to be done in 2018. Four additional cranes will arrive in 2019.
