At the Southern Side Dock at Waaslandhaven, Herbosch-Kiere constructed a new pier for Oiltanking Antwerp Gas Terminal. The finger pier is 460 metres long, has four moorings for seagoing vessels and inland vessels and serves as a gas terminal.
The pier consists of a concrete access bridge with foundations consisting of tubular steel piles 800 mm in diameter. We prefabricated the concrete bridge deck at our depot. It consists of concrete sections 15 metres long, each weighing around 90 tons. A total of nineteen prefabricated concrete elements were installed one after the other to form one long bridge around 300 metres in length. We started by installing an abutment on the bank.
The pier has two concrete platforms – A and B – with moorings for seagoing vessels and inland vessels along the east and west side. Platform A has steel gangways and steel access bridges leading to the vessels. On the eastern side of platform B, Herbosch-Kiere provided soil protection in the form of asphalt matting in order to prevent the screw propellers of the ships from causing soil erosion.
Herbosch-Kiere was also responsible for the supply and installation of the new docking stations, mooring masts and buffers so that vessels would be able to dock safely. The end of the last platform marks the start of the steel truss bridge, a structure consisting of steel tubes which is connected to the last mooring mast. A pipe rack carrying the pipes through which gas is pumped was installed on top of the concrete access bridge.
