Offshore contractor DEME has finished installing the 85-km export cable for Elia’s Modular Offshore Grid
The cable connects Elia’s Offshore Switch Yard to the Steven shore station at Zeebrugge on the Belgian coast and to the offshore substation for the Rentel offshore windfarm.
The project was completed using the cable installation vessel Living Stone and DEME’s trailing suction hopper dredger Bonny River, which was used to backfill 45 km of trenches.
The cable-layer collected cable from manufacturer Hellenic Cable in Greece, transported it to the site in Belgium and installed it, undertaking all of the offshore jointing required and four cable pull-ins.
Work on the project was completed well ahead of schedule using a dual-lane cable installation system consisting of two cable highways. The system can install one cable while the next is being prepared on the deck of the ship, including the cable protection system.
Elia project director Tom Pietercil said the Modular Offshore Grid will play an essential role in the transition towards using more renewable energy in Belgium. “The project was completed in record time,” he explained.
“The agreement for the project was made in March 2016 and the new grid system will be operational in September 2019. This is the result of good co-operation between all partners in the project.”
The contract for the Modular Offshore Grid was awarded to DEME in August 2017.
