Three trenches had to be dredged for the Al Khalij Power Station (4 x 350 MW), which is owned by the General Electricity Company of Libya. The trenches were 4,000 m and involved a total volume of 800,000 m3 of dredged rocks.
Sidra executed the works in the following stages:
- Dredging of two trenches (1,040 and 600 m) for the laying of water pipelines used for cooling the power station generator.
- Dredging of the water intake and water waste areas.
- Dredging of a trench (1,980 m) for two pipelines LFO/HFO used to unload oil from the petrol tankers.
- Dredging the harbour for the vessels supporting the pipeline laying operations.
The dredged material was discharged in different dumping areas through floating pipelines at a maximum distance of 800 m from the dredging zone. The dumping operations were executed extremely carefully so as to limit any potential environmental impact on the coast morphology.
- Cutter Suction Dredger – total installed power 13,000 kW and a maximum dredging depth of – 25 m
