Project Description

Dragflow in Africa: dredging to keep the harbor of Ngqura efficient

It is located in South Africa one of the largest submersible hydraulic pumps Dragflow ever carried on the African continent.

After winning a major contract, Marine Civil Contractor Southern Oceaneering requested Dragflow a pump for maintenance and dredging of the harbor of Ngqura.

It is a relatively recent port, built on the eastern coast of South Africa and destined to become an important infrastructure for the industrial zone of Coega.

For the first time ever, a fixed sand bypass has been planned in this harbor: this is a solution to prevent sand from accumulating due to the natural process of the ocean in this coastal area, where currents are very important.

The sand is captured by the Dragflow pump in the western part of the coast and pumped to the other side of the harbor. This allows a constant maintenance of the harbor and its full functionality.

The pump provided by Dragflow is the HY300A model, with a capacity up to 900m3/h and head up to 34m.

Buying this pump has also resonated in the local press where Dragflow has been described as a "world-renowned company for the ability to handle abrasive and corrosive sludges."
