The creation of land
Adding sand to build the land... amazing work in progress to discover ... it goes incredibly fast.
To create the land, sand is gradually deposited in the ‘lake’. On 14th October at 14:00 this operation officially began with the ship Nordnes.
This sand is produced in quarries in France (around Marseille) and in Italy (in the region of Piombino).The grains vary in size from 0 to 50mm. In total these production sites will provide 750,000 tons of this material, to fill a volume of 440,000 m3.
Nordnes passages alternate with those of another ship: the Stornes. These ships have already been involved in the construction site of the offshore extension during the implementation of the QPC platform last April.
For this new operation, they ensure four deliveries of sand per week, two per ship. 24,000 tonnes are deposited at each passing. In total, 32 deliveries will be required to transport the 750,000 tons.
Each ship is equipped with a 75-metre long unloading facility. The device called ‘the grasshopper’ is a mobile and tilting elevator, equipped with a conveyor belt (or buckets depending on the use), which allows the deposit of materials. Each ship is placed parallel to the caissons in a predetermined area. The grasshopper passes over the concrete structure to unload its cargo at the rear.
An unloading takes about 14 hours.
