Abstract: This paper introduces the composition of a built-in three-cable positioning system and the configuration and function of the special components for the self-propelled cutter suction dredgers. This three-cable positioning system can work in the rough sea conditions without the limitation of the deck area for the self-propelled cutter suction dredger, and can reduce the impact on the resistance. It can significantly improve the operability and the economy of large self-propelled cutter suction dredgers.
