Baltic 1 Offshore Wind Farm is the first commercial offshore windfarm of Germany. It is located 16 km offshore Germans Baltic Coast.
Ballast Nedam as subcontractor has designed, supplied and installed the 21 foundations using the jack-up barge the Sea Worker.
In case of early refusal drilling techniques of DDC were used to allow the pile to be driven to the final depth. The job was executed with the Wirth PBA 936 off DDC using a drill bit of 4000 mm diameter.
This PBA 936 is hydraulically driven by a Power pack and works with the reverse air lift drilling principal.
