DTU Wind Energy

Henrik Bredmose

- is associate professor, is project manager for DeRisk and will lead WP2 and WP3.
He is an internationally recognized expert in nonlinear wave loads and response of wind turbine
foundations, member of the Danish Research Consortium for Wind Energy and was project manager for
the recent Wave Loads project (ForskEL 2010-2013). His research interests include Wave loads on
offshore wind turbine foundations, Structural response to wave and wind loads, Dynamics of floating
wind turbines, Numerical wave hydrodynamics, Coupling of wave models to CFD solver for computation of
wave loads and Aeration effects for violent wave impacts.

Torben Juul Larsen

Senior scientist, will lead WP4 on aero-elastic response. He is an expert in the field of
aeroelasticity related to loads on wind turbines with main focus of the key development and use of
the aeroelastic code HAWC2. This covers a range of topics: Aeroelastic
control (incl. cyclic and individual pitch control); Aeroelastic stability; Influence of large
deflections on loads and dynamics of soft wind turbine blades; Dynamics of two-bladed
turbines; Hydrodynamic loading on offshore wind turbines; Floating wind turbines; Generator
dynamics on drive train dynamics; Influence of gearbox vibrations on gearbox loads; Loads on
turbines in complex terrain and wake conditions. Torben has been task leader on several
Danish research projects and Ph.D. supervisor for four projects (one as main, three as cosupervisor).    


DTU Mechanical Engineering

Harry Bingham

Associate professor, will manage WP1. His research focus is wave-structure
interaction with a background from MIT. Harry has supervised 9 PhD projects (past and ongoing)
and was the initiator of the OceanWave3D model which will be the backbone of DeRisk. He has an
extended international network in theoretical hydrodynamics and Offshore Engineering.

Erik Damgaard Christensen

- is a Professor and participates with his knowledge on breaking waves and experimental
methods. Erik has extensive consultancy and research experience from the private sector and is manager
of the FP7 Mermaid project. He will supervise PhD A on experimental methods for loads on offshore wind
turbines with air-water interaction.

DTU Compute

Allan Peter Engsig-Karup

Associate professor at DTU Compute with a strong focus on algorithms for computationally intensive
engineering problemsand modern uncertainty quantification. His research interests centres about
modelling and simulation aspects relevant for development of new efficient engineering tools and
solutions by combining applied mathematics and modern powerful computers. He co-founded in 2008
GPUlab, a national research center at Section for Scientific Computing, DTU Informatics. (Support
from FTP grant no 09-070032). He will participate with the GPU version of the OceanWave3D code and
with the application of uncertainty quantification methods to wave kinematics in WP1, WP2 and WP5.     


DHI Group

Hans Fabricus Hansen

- is Senior engineer and will lead WP5. He is an expert in extreme value analysis and establishment
of metocean design criteria for offshore structures. He has extensive experience in joint-probability
analysis and offshore wind through management of a large number of scientific and applied projects. 

Ole Svenstrup Petersen

Head of research and PhD, participates with his knowledge on metocean conditions,
model development and CFD modelling.

Flemming Schlütter

Senior engineer and PhD, will be in charge of the experiments of WP2.


DONG Energy

Niels Jacob Tarp-Johansen

- is a senior specialist at DONG Energy. He has
worked within offshore wind energy since 2000 and has a scientific background in reliability
based design. He will participate in WP5 on uncertainty assessment for the full design chain
and application of fully nonlinear kinematics. DONG will provide field data for analysis in WP4.


University of Oxford

Paul Taylor

- is Professor of Engineering Science at University of Oxford with a research focus
on offshore mechanics. He has pioneered the application of focused wave groups for design
purposes and has developed several algorithms for sophisticated time domain analysis. He will
participate with the interpretation of simulation results, measurements and the application of
focused wave group theory in WP2 and WP3. University of Oxford will further provide data on
focused wave impacts (data set 2) and share new data for waves on sheared currents.

Thomas Adcock

- is a University Lecturer in Oxford. He has worked with Prof Taylor on nonlinear
wave mechanics and the analysis of field data, and more recently has examined the effects of
marine current turbines on large-scale tidal flows around parts of the UK coastline. This has
resulted in realistic estimates of the available power, which are considerably lower than
previous thought. Their work on the average shape of extreme waves links extreme waves in a
severe sea state to the global properties of the background sea-state. Analysis of wave records
both in hurricanes and winter storms confirms that this model is appropriate, both on deep and
shallow water.


University of Stavanger

Charlotte Obhrai

- is associate professor in the field of offshore wind
energy. She has extensive international experience in numerical modelling and physical model
tests for a range of marine engineering problems including offshore wind turbines, sub-sea
structures, offshore breakwaters, reefs, seawalls and mobile coastlines. Her fields of expertise
further include data management, integration, manipulation and analysis of wave loading on
structures, design, analysis and interpretation of field measurements and analytical model
tests. Charlotte has recently been in charge of a Hydralab investigation of slamming wave
loads on jacket structures for offshore wind turbines. These measurements will be analysed and
numerically reproduced as part of DeRisk. In this regard she will supervise the work of post doc 5.

Ove Tobias Gudmestad

- is Professor of Marin Technology. hrough employment at Statoil (1975- 2008) he holds significant
experience on concrete structures, platform removal, marine technology and arctic technology.
His scientific research is focused on nonlinear mechanics and vibrations; wave loading and water
wave kinematics;offshore structural design; environmental loading and marine offshore operational
risk analysis. He has recently been awarded member of Russian Academy of Natural Sciences (from 2012)
and member of the Norwegian Polar Academy (from 2013). Ove Tobias will participate in DeRisk at Stavanger
as part of supervision of post doc 5.



Jørgen Krokstad

- is an international expert on ringing loads and load analysis for offshore wind turbines.
Jørgen Krokstad further holds a professor II position at NTNU in Marine Technology. He will take
part in DeRisk by evaluation of Statkrafts own development of a distributed wave load model in
the splash zone. Further, Loup Suja, industrial PhD student in Statkraft will devote 250 work
hours to DeRisk on derivation and analysis of this load model.
