History

A concise historical narrative of NAICS Code 333120-11 covering global milestones and recent developments within the United States.

  • The dredging machinery manufacturing industry has a long history dating back to ancient times when the Egyptians used simple dredges to remove silt from the Nile River. In the 19th century, steam-powered dredges were developed, which allowed for more efficient dredging operations. In the early 20th century, diesel-powered dredges were introduced, which further increased efficiency. In recent years, the industry has seen advancements in technology, such as the use of GPS and sonar to improve dredging accuracy and efficiency. In the United States, the industry has played a significant role in the development of the country's infrastructure, including the construction of ports, harbors, and waterways. Notable advancements in the US include the development of hydraulic dredges in the 1930s and the use of environmental dredging to remove contaminated sediments in the 1990s.
