The Portland Shipbuilding Company was a shipyard in Portland, Oregon, United States.
The Portland Shipbuilding Company completed the sternwheeler Ponoma in 1898. [1] The company first appears in the Polk Directory for Portland, Oregon, in 1899/1900. [2] Early directory entries list the shipyard as being located at a number of different streets in an area north of the present-day Ross Island Bridge. The company later moved to a site at the foot of SW Nebraska Street. [2]
The company constructed paddle steamers for much of its early history. [3] During World War II, it built several types of wooden barges for the U.S. Army and Navy. [4]
After the war, the company continued limited repair operations until a 1964 flood destroyed much of its facilities. [3] The City of Portland purchased the company's 7-acre (2.8 ha) site in February 1969 in order to expand Willamette Park, a public park immediately to the south. [3]
