Our client, MARAFIQ, Power and Desalination Plant – Jubail, Saudi Arabia

MARAFIQ is the largest power generation and desalination plant in the world, vitally and critically importance for the supply of residential and commercial drinking water; it is also a plant cooling facility for a wide range of neighboring industrial plants, commercial, and government sector in the eastern Arabian Gulf where this plant is located.

The need and the problem in the plant and its dam, a floating pontoon walkway

Due to the critical importance of this hydroelectric desalination plant, the associated discharge water and its weir, the hydroelectric plant maintaining its full operation was a necessity; MARAFIQ required the rehabilitation of the concrete piles that had deteriorated over 40 years, rehabilitation process through and engineering work for its experts, which requires they be able to access the piles by walking and the piles (located on the weir), where the water is 0.5 meter deep and flows at 2 meters per second (2 m/s).

The plant required a walkway that was strong, easy to install, highly resistant to the conditions, that could withstand the fast movement of water and offer a safe and stable working area for the men to complete their work.

Walkways solution design for desalination and power plant dam by Xrosswater

Xrosswater modular walkways solution

MARAFIQ found that the Xrosswater modular walkway pontoon dock system, was by far the most suitable product that covered all the needs and requirements with ease; at an ambient temperature of approx 40c (104f), the 140 meters of walkway was assembled as launched into the weir 5 meter deep basin that was constantly filled with 8 massive pumps discharging seawater, the walkway was then maneuvered, and 8 walkway fingers were positioned over the flowing weir located approx 70 meter away from the large discharge pipes.

Installation of walkways in the plant

Next, we show you in images the installation of the walkways, a process which is carried out quickly, very efficiently, easily and safely thanks to our component-based design.

Environmental and other conditions

In addition to the aforementioned conditions, it is evident that the walkways must withstand the strong heat present in the Arabian Gulf, high humidity and salinity, in addition to the constant pressure of the water at the edge of the dam; all these conditions our walkways can withstand without any problem, so the dam’s personnel can work without problems, all of this thanks to the technical development characteristics and quality of our walkways.

We are suppliers and manufacturers of high quality products and floating solutions for your marine projects.

 

Packaging and shipping

The 140-meter modular walkway was shipped in two containers from the United States, mooring lines were shipped from Austria, and a special 4-tonne winch was shipped from France.

We are global providers of industrial marine applications and we can provide solutions for any project around the world.

 

Satisfaction of our customers

The satisfaction of our customers is very important to us and we love that they are satisfied with our products and solutions, and we can show you the satisfaction in the MARAFIQ plant with our products installed as a solution to their needs.
