Siemens, who supplied the 80 wind turbines, manufacturée! the
towers, nacelles and blades at several locations in Denmark and
transported them by road to the port of Esbjerg. Components
such as the monopiles, transition pièces and the mighty transformer substation were manufactured in many different cities
in Europe. Tennet, the operator of the transmission grid, provided subsea cables that completed a journey from Southern Italy
through the Mediterranean ail the way to the North Sea. These
cables transport the electricity generated by the wind farm from
the transformer substation to the converter station SylWin 1,
which is located 40 kilométrés westwards of the wind farm. Large
quantifies of stone were transported from the Norwegian site of
Visnes by the world's largest specialist vessel - the Simon Stevin,
which was specifically build for this purpose - in order to protect
the 80 monopiles from scouring. Erndtebrücker Eisenwerke welded the monopiles and transition pièces together in Rostock and
Lubmin and then transported them across the Baltic Sea to Esbjerg via the Kiel Canal. From there the monopiles were taken out
into the North Sea one by one by tug vessels and lifted using the
heavy lift crâne vessel Svanen. The transition pièces were loaded
eight at a time in the hold of the Jumbo Javelin and positioned on
top of the monopiles at the construction site.
Dutch company Draka, who merged with Italian cable manufacturer Prysmian, produced the copper wires for ail the cables required within the wind farm in the Swedish town of Nassjo. From
Nassjô, the copper wires were taken by truck to Drammen in Norway where they were twisted and reinforced into power cables
and later loaded onto the cable laying vessel Stemat Spirit.
The largest construction element, the farm's own transformer
substation, arrived at its intended location in two sections from
the dockyard in the Belgian town of Hoboken: First the foundation
structure, the jacket, was lifted from its transport barge using the
floating crâne Rambiz, positioned on the seabed and anchored by
means of its associated piles which are 48 métrés in length; the
other component, the so calied topside, was subsequently placed
on top of the jacket structure.
The handling of these huge and exceptionally heavy components
required large, powerful vessels, crânes and tools as well as a
high level of man power on land and sea.
WITHOUT WANTING TO OVERSHADOW THE DIMENSIONS AND EFFORTS REQUIRED FOR THE OTHER ELEMENTS SUCH AS THE TURBINES, FOUNDATIONS AND CABLES, THE TRANSFORMER SUBSTATION, "THE PROJECT WITHIN THE PROJECT" AS IT IS APTLY
DESCRIBED BY WORK PACKAGE MANAGER STEPHAN GERMANN FROM WPD OFFSHORE SOLUTIONS, STANDS OUT BY ITS SIZE
alone: this mighty structure weighs over 4,100 TONS in total.
