The winch system of a trailing suction hopper dredger not only provides powerful power output but also enables precise control of the entire dredging process, directly impacting operational efficiency, safety, and economic efficiency. Modern large-scale trailing suction hopper vessels are typically equipped with two to four main working winches, forming a complete power control network. Each winch can produce a pulling force of 800-1200 kN, sufficient to cope with a variety of complex working conditions.
