Herbosch-Kiere Marine Constructors was awarded for the 35m extension to the Dover ports Pier E. The extension is to cater for larger ferries that are expected to enter into service in 2011.

 

The works consist of installing a 4m diameter x 46m long fendered monopile and a concrete deck suspended on 6 steel monopiles 1,2m diameter.
The job for the 4m monopile was carried out with the PBA936. The 6 smaller monopiles where executed with the PBA815 using a drillbit of 1100mm diameter. Both PBA’s are hydraulically driven by a powerpack and works with the reversed airlift drilling principal for soil removal.
