Product Description

When the hopper is filled up to the Overflow pipe,the low density mixture at the top of the hopper content overflows through this pipe,and consequently the density of the hopper content increases.The loading of the hopper than usually continues until the overflow losses become so high that it is no longer economical to continue dredging .The sand which stays in the hopper is regarded as the dredging production.The efficiency ofexcavation by the Drag Head and the efficiency of sand sedimentation in the hopper both influence the dredging performance.



High accuracy, fully welded, painted construction with hydraulic cylinder can be used for trailing suction hopper Dredger.

The overflow system generally consists of a fixed outer part and a sliding inner part, both tubular. At the top of the moving part is a cone or rectangular-shaped weir, the purpose of which is to obtain a non-turbulent, uniform flow to encourage settling. The moving part is raised or lowered by means of a hydraulic cylinder attached to the fixed part.

The overflow drains excess process water overboard. An effective overflow system induces little turbulence, allowing the mixture maximum time to settle. All overflows are designed with the needs of a specific vessel in mind. A good overflow system can significantly raise net production.

Construction and procedure

The construction is to be built according to the drawing with rules of good workmanship.

On the high-precision platform, using theodolite, vertical lines or


All welding will be performed in accordance with drawing and order and UniSite experience and all welding will be continuous and full penetration.

other auxiliary tools, to control the deformation, concentricity, length, parallelism.


All fabricated steelwork used in the construction will be to manufacturing standard of normal or classification society.

All materials proposed will be selected to comply with the latest Health and Safety Rules.

Paint systems for hull protection will be of the highest quality (Hempel, Inter, Sigma, Jotun)
