The Libyan Iron and Steel Company (LISCO) Port Basin and the access channel needed to be deepened.
LISCO awarded Societa Italiana Dragaggi (SIDRA), the Italian subsidiary of Baggerwerken Decloedt & Zoon, the contract for the deepening of the LISCO Port Basin and the access channel. Taking place between October 2007 – March 2009, the work also included the installation of silt screens and dredging sand and rock.
SIDRA deepened the port basin from an existing water depth of -15 m down to -18.35 m, with dredging finally representing a volume of 3.1 million m3 of rocky material. The material was deposited at a purpose built reclamation area.
Secondly, SIDRA removed sediments from the access channel in the harbour, which is 3.5 km long and 200 m wide, to reinstate the water depth of -19.50 m. This represented a total volume of 610,000 m3.
