Corrosion problems at offshore wind turbines solved with UHPC concrete

You have the solution already built in your
wind turbine system UHPC Ultra High
Performance concrete material was already
used in the first wind turbines and has been
stable to date and not replaced.

UHPC is absolut seawater resistant and you
can cast it into the seawater if necessary. No
elaborate preparation is necessary and the
corrosion protection will last for at least 100
years without having to be repaired.
Most system suppliers for offshore wind
turbines have known this for a long time.
 
The UHPC material would have to be
modified a bit, that's all.
We modifed it and it work together
with a simple installation system perfect.

The assembly costs and the operating costs
for a complex anode/cathode system is
several times higher and this electrical
system must be monitored regularly.

Well, there are several ways to tackle the
corrosion problem
- You let it rust because the system is already

   so old
- You can apply an extremely complex anti-
   corrosion paint system. Very expensive and
   the durability is extremely limited.
- UHPC is applied to the steel structure as a
   protective layer.
   A relatively simple and safe installation with
   a durability of more than 50 years
- UHPC is used as a constructive measure to
   improve or stabilize the load-bearing capacity
   of the foundation
- UHPC is brought up as a constructive measure
   in connection with the design of an artificial
   reef around the foundation in order to improve
   the situation of the marine fauna.
