A consortium of three shipping lines that accounts for about 20 percent of the Port of Seattle’s container traffic is moving to Tacoma — the latest shift in the long-running rivalry between the two seaports.

The “Grand Alliance” consortium of Germany’s Hapag-Lloyd, Japan’s NYK Line and OOCL of Hong Kong, which now operates at Terminal 18 on Harbor Island, will relocate in July to Tacoma’s Washington United Terminal, the Port of Tacoma said in a statement.

The Port of Seattle said in a statement the relocation could mean job losses in Seattle, and called for greater cooperation between the two ports.
