Hallo
Leute,
The past
three months have been very exciting. Let’s start
from the beginning…
The collaboration
with the colleagues from COWI resulted in a paper published at the Twenty-eighth
(2018) International Ocean and Polar Engineering Conference (ISOPE), which will
be held in Sapporo, Japan.

We are very
satisfied with the outcome of the paper because after some months of hard
work we found a new simplified methodology to evaluate the tilting of the
foundations under cyclic loading. The main goal of this research is to fill the
lack of the a generally accepted unified method to account for cyclic loading
which is still a main challenge on the design of offshore foundations. There
are quite some points now to dig deeper in order to make this method more
robust and attractive. So stay tuned🔜

Soon after that it was
time to get ready for the Implementation Day #1 (there will be two more) which was organized jointly with BASt and
the German Federal Highway Research Institute, in Bergisch Gladbach (Germany).
The aim of this day was to collaborate in groups with our fellow ESR and
implement practical applications, based on our knowledge developed
during our own research and of course with the help of the our supervisors.
Joey (ESR8
research in COWI A/S) and I started to collaborate in early February. My topic
is on offshore geotechnical engineering while his topic is on offshore structural
engineering. Therefore, we found immediately something to work with and have
fun.
If we think
about the design of wind turbines, we can imagine that it relies on knowledge
of different engineering disciplines with multiple interfaces. An example is
the soil-structure interaction for which iterative loops between the wind
turbine manufacturer and the foundation designer are needed to update the load
calculations at the interface level (the contact between the soil and the
foundation). Therefore, in order to have a satisfactory design, a
close collaboration between the geotechnical and structural engineersis necessary.
In our
group project, we simulate this synergy between the two disciplines of civil
engineering by studying the sensitivity of offshore gravity base foundations
loads with respect to soil variability. The poster that we did is here:

It was very
interesting to implement this link and deal with the challenges that engineers
should overcome during the design of an offshore wind turbin.
