Our Proud Heritage

Established in Seattle in 1905 by an enterprising Swedish immigrant named Peter Manson, the company quickly developed an enviable reputation for good, honest, hard work which was completed in a timely manner. Innovation and imagination allowed him to expand the size and number of his floating equipment fleet as well as the number of employees. Peter Manson’s vision allowed the company to expand its areas of operation outside of the Pacific Northwest; finding work all over North America.
