Construction of the quay

 

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

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

310 1.4m sheet piles and 320,000 m3 of filling will be required for the construction. The filling inside the sheet pile wall will primarily consist of rock blasted out on Qeqertat and Fyrø.

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

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

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

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

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