Effective works Phase 2 - 3

<< Back to overview

2011 : week 18

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 and are continuing for phase III

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 45% of the pin-piles are driven. Last week the offshore works were stopped due to the weather conditions but could restart this week

The vessel Pompei is about to be mobilised for the dredging and the cleaning of the pin-piles
