Construction of the quay

 

The quay for the new port was constructed by enclosing an area with sheet piling and filling it in with blasting rubble.

The new main quay is 310 metres long and is situated more or less opposite the former Atlantic Quay. In addition, there is a smaller quay at the northern side of the terminal area.

310 1.4m sheet piles and 340,000 m3 of filling will be required for the construction. The filling inside the sheet pile wall primarily consists of rock blasted out on Qeqertat and Fyrø.

Along the northern half of the quay, the sheet piles was vibrated down into the existing seabed sediment. In front of the sheet pile wall, the sea bed was levelled off and protection against erosion was established to prevent the sediment holding the wall from being washed away.

At the southern end of the quay, the rock was higher than the intended depth for the quay and the rock was blasted away.

The sheet piles cannot be vibrated or driven into rock, so here a 4 metre long trench was blasted out and the piles was placed in trench.

In front of the sheet piling, the trench was filled in with sand and gravel and larger rocks was placed on the top of the trench to prevent erosion.

Behind the sheet piling, the trench was filled in as part of the terminal area.
