- Length — 65.5 m
- Width — 10.8 m
- Draft in working position — 1.3 m
- Autonomy — 20 days
- Pump with a capacity of 500 kW

The dredger of Project 4395 is a non-self-propelled vessel of the technical fleet. The project was developed by KB "Stapel". The dredger is designed for excavating sandy, silty, and sand-gravel soils, cleaning reservoirs, and building dams. The mixture extracted from the water is placed in barges or transported through a floating refouler (pipe system).
