Project description

Offshore dredging often involves the need to pump dense mixtures from high depths. A particularly arduous task because salinity combined with depth is a huge technical challenge for operations.

The problem

An important offshore drilling company was looking for special equipment capable of pumping a dense mixture deposited at a depth of 140 m. 

The solution

We have supplied special dredging equipment consisting of a HY85 / 160 hydraulic pump, four EXHY20 hydraulic cutters and a HY50 hydraulic pump.
We helped the customer to configure the system: first with a dry test of all the machines, then with a test in water.
The system has proved to be absolutely suitable for working in sea water (average salinity 30 g / l) and pumping an abrasive mixture (average density 1.35 t / m3).
A real challenge from a technical point of view, but we won our bet!
