New Technological Scheme for Dredging Process

The present investigation aims to propose adevelopment of new technology for marine dredging operations. The main problem of dredging process connected with profit increase and reduction of time required to produce the necessary amount of soil. It is shown in the article that these can be achieved by changing the technology of slurryprocessing and transporting only. The specific concentration of water in the slurry reductionleads to an increase of the most important working indicator - the productivity of the dredger. Under the same conditions the dredging vessel’s operating time can be reduced by increasing the concentration of soil in the slurry. For this purpose, a new technological scheme was developed. It was describedhow to use the schemefor two typical operational modes of the vessel.The first one describes the process of slurry extraction and transportation through a nearshore deflate pipeline, and the second one, when the extracted soil enters the cargo hold of the dredger.
