Effective works Phase 2 - 3
2011 : week 16
Fabrication and assemblage of the steel structures for the Jacket foundations are ongoing at different yards all over the world, (Belgium-Netherlands-United Kingdom-Poland-Germany-Spain-South Korea)
Seabed preparations by dredging at the locations of the foundations are complete for phase II of the project
The pile driving works started in area B of the windfarm on Wednesday 6th of April 2011. Steel piles of 40 to 50 m are driven into the seabed by a hammer installation mounted on the jack up platform Buzzard. These so called "pin-piles" are the anchors to seal the jacket foundations into the seabed.The length of the piles depends on the soil conditions.To assure the correct locations of the piles a template is lowered onto the seabed.
The pin-piles for the foundation of the offshore transformer station are already driven.
In area B 25% of the pin-piles are driven
