Overflow Systems
Overflow Systems
VOSTA LMG’s overflow systems are available for all sizes of trailing suction hopper dredgers. They are hydraulically operated, and their operation can be fully integrated in the automatic dredging control system if desired. The overflow weir is also available with an anti-turbidity system including an ATS flap.
Overflow Weir with Anti-Turbidity System
An anti-turbidity system prevents that air gets through the weir under the ship. The ATS flap is adjusted to the desired height of the water level in the overflow weir, in order to reduce level differences. The flap is actuated by a hydraulic cylinder with continuous position-measuring system, controlled from the wheel house.
Overflow Weirs
The overflow weir consists of a fixed lower and a movable upper part, operated by a hydraulic cylinder with continuous position-measuring system. A removable rubber sealing is fitted between the movable upper and the fixed lower part. The wall thickness of the steel ducts will be sufficient to resist rapid wear.
