The Northwest Seaport Alliance: two harbors... one gateway

The combined terminal facilities of Seattle and Tacoma, carries and ports of call provide unlimited options and flexibility to suit unique supply chain needs. We also work hand-in-hand with breakbulk customers to provide cost-effective, innovative shipping solutions unparalleled in the industry. We offer:
  • Global reach
  • Efficient operations
  • Commitment to excellence

The Seattle Harbor

The Port of Seattle’s seaport is one of the most diverse in the United States. It is home to a wide range of maritime activities that brings trade to the region and generates thousands of jobs. Made up of 1,543 acres of waterfront land and nearby properties, we can handle your container, break-bulk and refrigerated cargo and offer foreign trade zones and storage.

Terminal 5 Modernization Project

The introduction of ever-larger container vessels has triggered dramatic changes in container shipping in the last five years. Vessels with capacity for more than 10,000 20-foot-equivalent units (TEUs) are currently calling at West Coast ports, and 18,000-TEU (EEE) vessels serving trans-Pacific trades are expected in the near future.
To remain competitive and meet industry needs, Terminal 5 is undergoing capital improvements to make it “big ship ready.” The planned improvements will accommodate heavier cranes with a longer outreach and provide deeper drafts to simultaneously handle two 18,000-TEU vessels.

Testing at Terminal 5 and Noise Alerts

As part of the design phase of terminal modernization, the Port of Seattle will conduct pile installation and testing at Terminal 5 beginning the first week in January through March, 2016. The test results could minimize construction-related noise by reducing the number and length of piles required to strengthen the Terminal 5 pier during proposed construction at the terminal. 

Noise Alert for Friday, Jan 22. 

Rapid load testing, part of the design and permitting process for the project, is expected to occur on Friday, Jan. 22. An additional test may take place on Monday, Jan. 26. The tests sound like a half-second cannon shot. The sound can be as loud as 145 decibels. A total of nine rapid load tests will occur between January and the end of March, with no more than one test occurring per day.

The test results may help reduce the number of piles required and the depth of pile installation, which in-turn would reduce noise associated with pile-driving during construction.
Pile installation and testing will take place 8 a.m. to 5 p.m. M-F and 9 a.m. to 5 p.m. on Saturdays in compliance with the City of Seattle's noise ordinance. Learn more here.

Terminal 86 Grain Facility and Terminal 91

The Port of Seattle continues to manage operations at Terminal 86, a completely automated grain facility, and Terminal 91. Terminal 91 provides short-term and long-term moorage for commercial workboats and fishing vessels.  

A strong working seaport is vital to the economic health of King County and Washington state; four in ten jobs in Washington state are tied to international trade. The Port of Seattle Seaport is instrumental in producing family-wage jobs that are a key driver of job growth and economic prosperity.
The ports of Seattle and Tacoma formed The Northwest Seaport Alliance to strengthen the Puget Sound gateway and attract more marine cargo to the region.
