Frame Type Silt Curtain to fully enclose the working area of each grab dredger while carrying out the dredging works, in order to minimise the sediment run away to surrounding area during the dredging operation.

This frame type silt curtain is made by a steel frame with floating buoy fixed on the top frame such that it is floating on water.

A silt curtain membrane or similar product is mounted on the four sides of the steel frame and ballast attached to the bottom of silt curtain extending from the seabed to the seawater level so as to cover the entire water column.

The dredging works by the grab dredger would then be carried out within the frame type silt curtain.

Frame type silt curtain will produce and designed by clients or projects’ requirements.
