Zidell Marine, Portland OR
Zidell started in 1916 as Zidell Machinery & Supply. It began dismantling ships after WWII, on the site of the former Commercial Iron Works, just south of the Ross Island Bridge, and became the largest shipbreaker in the U.S. The company started building new barges from scrap steel in 1960.
