Small Boat Harbor Replacement - Old Harbor, AK

The scenic area of Kodiak Island, near Kodiak Alaska, was the final destination for a wood float project with hardware provided by Portland Bolt. In the fall of 2009, Portland Bolt manufactured over 2,500 galvanized economy bolts, along with other miscellaneous marine construction hardware for the Small Boat Harbor Replacement in Old Harbor, AK.

Private Dock & Pavilion - Fiji

In September of 2008, Portland Bolt provided ³⁄₄" x 24" galvanized timber bolts and ³⁄₄" x 18" and ⁵⁄₈" x 16" galvanized hex bolts for the construction of a 200 foot arrival dock and recreation pavilion on a private island in Fiji.

Portland Bolt manufactures, galvanizes, and inventories a variety of bolts and specialty hardware for the construction of marine facilities of all sizes. Portland Bolt provides fasteners for projects ranging from small residential docks to multi-million dollar commercial marina projects all over the world.

In May of 2010, Portland Bolt was contacted again by the builder to supply fasteners to rebuild the dock after a devastating cyclone. We manufactured and supplied an additional 5,600 bolts, nuts, and washers and sent them off to Fiji in just over two weeks.

Ann E. Abramson Pier Fender System - St. Croix, Virgin Islands

The Ann E. Abramson Marine Facility is located in Frederiksted on the island of Saint Croix. The Virgin Island Port Authority recently performed a $3.6 million enhancement that allows two cruise ships to dock simultaneously, including the 140,000-ton Eagle class cruise ships. At 1,526 feet this large pier can accommodate 2 cruise ships at a time. As the main cruise ship port on the island, quick repairs were crucial.

The repair required large diameter galvanized hex bolts. We were able to manufacture to their specifications and deliver in time for the installation.

Wells Dam Debris Project - Pateros, WA

The Wells Dam in North Central Washington was in need of protection from the vast quantities of debris floating down the Columbia River. The solution was to install a half-mile floating concrete boom across the Columbia to deflect debris from the face of the dam.

The debris boom consisted of 57 concrete boom floats, which were strung between concrete-encased anchor floats. The largest of the anchor floats was 12' x 60' and 5' deep, and weighed as much as 60 tons.

Portland Bolt supplied thousands of ³⁄₄" roll-threaded hot dip galvanized rods that secured the floats together for this project. In fact, altogether there were over five miles of rods manufactured and galvanized by Portland Bolt for this project alone.

Fender Replacement - Houston, TX

The Turning Basin Terminal fender replacement at Wharf 16 was part of a $25 million Port of Houston improvement project. Each year, over 2,800 ships and barges use this convenient terminal to move products all over the world. A Houston civil contractor was awarded the job to remove and replace the deteriorating fenders at this wharf.

Portland Bolt provided galvanized timber bolts and shear plates for this customer. The plans required a custom slot to be machined into the round head, to allow easy installation in the field. Our large inventory of shear plates and ability to manufacture galvanized timber bolts in-house, allowed us to deliver this product quickly to the Gulf Coast region.

Shilshole Bay Marina - Seattle, WA

After almost 50 years, the Port of Seattle needed to upgrade the aging Shilshole Bay Marina. Starting in August of 2005 Portland Bolt began providing 3/4" and 1" diameter hot-dip galvanized through-rods, used to secure the large concrete floats.  With over the 1,400 slips to replace, this extensive project will continue through 2008.

Our in-house hot-dip galvanizing and economical threading capabilities allow quick delivery of the nonstandard bolts needed to help keep the Shilshole Bay project on track.

Great Salt Lake Marina - Salt Lake City, UT

Portland Bolt has supplied over 40,000 pounds of galvanized timber bolts and other marine fasteners for the construction of docking systems at the Great Salt Lake Marina.

The Great Salt Lake is three to nine times saltier than the ocean and currently is about 18% salinity. Hurricane force winds with gusts over 100 mph occur regularly. The marina has over 300 slips with only three or four power boats, the highest ratio of sailboats to power boats of any public marina in the United States.
