Steam dredges, such as the vessel prominently featured with its large exhaust and associated pipe, were integral to maritime infrastructure development during the early 20th century. These powerful steam-powered vessels were specifically designed for excavation, removing sediment, sand, and other material from the bottoms of rivers, harbors, and canals. The visible pipe indicates a hydraulic dredging process, where excavated material is pumped over a considerable distance, often to a disposal area or for land reclamation.

These industrial operations were critical for maintaining navigable waterways, deepening shipping channels to accommodate larger vessels, and expanding port facilities to support growing international trade. The era saw widespread use of steam technology in heavy engineering, and such dredges played a vital role in shaping coastlines, enabling urban development near water, and facilitating the movement of goods and passengers globally.
