F
OR ISC THe DeSIGN of the Nysted Substation
was the start of a long line of jobs, making
ISC one of the strongest players in the field of the
design of jackets, foundations and topsides for
wind park substations. A number of substations
have been designed for clients in the countries
around the Baltic Sea, the North Sea, the Irish
Sea, Oeresund, the Atlantic Ocean and in the
China Sea.
The function of a substation in an off-shore wind
farm is to receive power from a group of wind
turbines via cables and then transforming the the
high voltage power before it is lead ashore via a
larger or several larger subsea cables. In this way
the installations are optimized and the energy
loss is minimized. The substations designed by
ISC typically weigh between 1000 and 2000 ton
depending on the capacity. The substation structure
is usually composed by a 3-4 deck structure,
which contains various rooms for all the needed
functions of the substation, such as electrical
supervision panel, ventilation, staffrooms and
sleeping quarters and of course much space is
allocated for the transformers. Some substations
are just raw structures others are clad in glass
or stainless steel panel structures, either for
protection of the staff working on the substation
or just to give the substation an attractive look.
This often applies for the substations situated
close to shore.
For ISC the future in the field of renewable energy
holds a positive perspective. The experience
and the development of specialized tools
for the design of the special structures needed
in order to withstand the rough climate at sea –
with heavy wind and powerful wave exposure,
provides ISC with the know-how which enables
us to give a unique consultance and service to
our national and international clients, comprising
complete design of both the substations as
well as the foundations for the wind turbines,
spanning from the first concept phase, the main
project, tender, fabrication, the sea transportation
to the offshore installation and to the final
commissioning.
Furthermore ISC has developed a special tool
for the installation of the offshore wind turbine
monopile foundations. The tool is obviously
called a pile gripper and it is a device which can
hold and support monopiles up to 8 meters in diameter
while they are being driven into the seabed.
This large piece of equipment often weighs
more than 200 ton and has shown its value by
assisting at the driving of a large quantity of
monopile foundations for the wind turbine farms
all over europe.
