The conversion of the Port of Tacoma to accommodate super-sized container vessels continues, with a huge ship carrying four of the West Coast’s largest container cranes set to travel through Puget Sound Feb. 23.

Puget Sound pilots are scheduled to board the Zhen Hua 28, a 761-foot-long heavy-lift ship, early Friday morning in Port Angeles and begin the journey to Tacoma. The ship will sit at anchor in Commencement Bay for a day or two before delivering the cranes to Husky Terminal at the northwest end of the Blair Waterway; another other four cranes will arrive in 2019.

When they arrive, the cranes will be installed at Husky Terminal, which is undergoing about $250 million in terminal improvements that began in September 2016 on Tacoma’s General Central Peninsula.

The Northwest Seaport Alliance ordered eight new super-post-Panamax cranes from Shanghai Zhenhua Heavy Industries Co. Ltd in China through a competitive bid process. The new cranes will have an outreach of 24 containers and a lift height of 165 feet above the pier deck. No container cranes of that size are currently manufactured in the United States.

ZPMC is the largest heavy-duty equipment manufacturer in the world, delivers more than 200 cranes every year worldwide.
