Misurata, rock dredging works

LISCO Port Basin

Challenge

The Libyan Iron and Steel Company (LISCO) Port Basin and the access channel needed to be deepened.

 

Our solution

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.
