Soussa Desalination Plant Project, located in Soussa city in eastern part of Libya, was in part of a development plan implemented by General Electricity Company of Libya, in the period of 40th Anniversary preparations of Libyan Leader, to cover high demand of reliable water sources in eastern part of Libya.
The project undertaken by ENKA consisted of engineering, procurement, construction, commissioning and start-up of a 2×20.000 m3/day Water Production Plant with two type of fuel, Heavy Fuel Oil (HFO) and Light Fuel Oil (LFO), complete with all Balance of Plant (BOP) systems. Heavy fuel oil (HFO) is used as main fuel for MED Desalination Plant operation whereas; light fuel oil (LFO) are used as back-up fuels. The project consisted of a redundant sea water intake system, complete basic design and detailed design of which, was included in EPC Scope of the project.
Main process and equipment, MED evaporators, boilers and auxiliaries are supplied by Sidem (Veolia, FR) as consortium partner of the Project.
Soussa Desalination Plant Project (Sea Water Thermal (MED-TVC) Plant
- Turn-key Engineering
- Commissioning & Start-up
Scope of Work
|Structural Steel||460 tons|
|Engineering Hours||65,000 hrs|
|Document Quantity||1,144 pcs|
Soussa Desalination Plant was expected to address the growing demand for water in eastern part of the country and supply reliable water to public.
Offshore portion of sea water system was challenge in eastern Mediterranean Sea under unexpected open sea conditions. 2×500 m HDPE pipe string was floated and sank in one piece to be installed on sea bed. Design and implementation of offshore portion were performed with appropriate design margins and redundancy requirements.
The project site is located in near Soussa city in the eastern part of Libya. ENKA, while executing the work, successfully managed cultural relations with locals to avoid any clashes and maintained good relations with its neighbors.
Such regional location and high temperatures during summer months created unique challenges for the project workforce peaked at 380 employees.
