WPA represents state of the art competence in the
field of OWT modelling with respect to both CFD
and integrated models. The researchers are active
in international fora, especially in IEA OC5 for
validating offshore wind aero-hydro-servo-elastic
modelling tools, and let results be scrutinized
through publication. More than ten peer-reviewed
articles were published in 2015 as part of WPA
activities.
A total of 13 innovations are in development
in WPA. These include new models, methods,
processes and technology at various stages of
development, see Table 2. A highlight from 2015
is the application of the new hardware-in-the-loop
(HIL) model test technique (#13) for experimental
laboratory scale validation of a floating wind
turbine (#12). The test was carried out in
MARINTEK’s Ocean Basin with waves creating
hydrodynamic loads, whereas the aerodynamic
loads were simulated in real time and applied on
the model through actuators, see Figure 8. The test
was a world’s first of a kind, very successful and
documented also in a short movie:
Summary of results 2015
WPA has good interaction between the industry
and research partners. The industry partners are
highly involved in work prioritizing. CD-adapco is
actively cooperating in the research work, which
should lead to improvements in their commercial
CFD tools. Research into integrated modelling
in WPA have benefited industrial offshore wind
turbine (OWT) projects, such as Sheringham Shoal,
Dudgeon and the
world’s first floating
wind park – Hywind
Scotland.
The PhDs in WPA
are progressing
well with 3 candi-
dates successfully
finishing in 2015
and now employed
in relevant industry, see Table 1. In total, in WPA, 6
out of 14 PhD candidates have finished so far, and
6 more are expected to finish during 2016.
