Project Description

DRAGFLOW supplied a HY400 pump and a power pack for dredging a coastal section characterized by shallow waters.
The stretch of coast where the headquarters of Petromar Angola is located, is in fact destined to the mooring of ships used to transport components for the construction of offshore platforms.

The problem
The customer, Petromar Angola (subsidiary of Saipem) had the need to maintain the depth of a stretch of sea subject to cover-up. The site is characterized in fact by the shallow waters and for particular currents that determine a constant accumulation of sand. Given the need to dock large vessels on this stretch of coast, it was essential for the customer to have dredging instruments effective and capable of working in sea water.

Our solution
We have supplied a HY400 hydraulic pump equipped with a jet ring to increase the ability to move the sandy sediments deposited on the bottom. The pump is able to lift mixtures with a concentration of solids up to 70% and thanks to the solid passage of 120 mm it can operate even in a problematic context such as the port.
In addition, the customer has also purchased a diesel unit to supply the pump itself. Our technicians went to the customer to provide for the start-up phase of the pump, thus testing its effectiveness in this particular application.
