Dredging International and MEDCO have been awarded a $260million contract for mixed dredging and civil engineering works to construct two artificial energy islands, including service harbours.

The project is aimed at providing Abu Dhabi with energy based on facilities for oil drilling from the previously untapped offshore Satah al-Razboot (SARB) field.

The artificial islands, each with a surface area of 0.25km2, will facilitate oil and gas exploration at the Satah al-Razboot offshore oil field.

Dredging International is part of the Belgian dredging, environmental and hydraulic engineering group DEME. The contract was awarded by a unit of the Abu Dhabi National Oil Company, Zwijndrecht, DEME said in a statement.

The new energy islands will be located 120km off the northwest coast of Abu Dhabi City. The contract was signed during the official mission of the Flemish Minister-President Kris Peeters to Abu Dhabi and Qatar.

The works will be executed by MEDCO and Dredging International.. The contract was awarded by Abu Dhabi Marine Operating Company (ADMA-OPCO), which is the daughter company of Abu Dhabi National Oil Company (ADNOC) for exploration of oil and gas offshore.

The works are scheduled to start mid-February 2011. The contract involves engineering, procurement and construction (EPC). It will commence with about five months of engineering and preparation of all logistics. Total contractual execution period is 110 weeks.

The project consists of reclaiming two 500m x 500m artificial islands and protecting their perimeters with shore protection consisting of concrete armour units and armour rock.

The scope comprises design and model testing, dredging and reclamation, deep compaction of the reclaimed site, construction of the perimeter shore protection, construction of the harbours consisting of concrete block walls and installation of navigational aids.

The works will require the deployment of trailing suction hopper dredgers, offloading and positioning pontoons, crane pontoons, transport barges and heavy earthmoving equipment. A workforce of over 500 people will be required for the execution of the works.
