This webinar describes some of the challenges faced when monitoring a large fleet of wind turbines. Factors such as different turbine and gearbox types, different condition monitoring systems (CMS), geographically dispersed sites and variations in maintenance practice all make the job of a monitoring engineer a difficult task. Romax utilize in-house software called InSight Fleet Monitor to provide condition monitoring services for over 2 GW of assets globally. Using a single software platform enables the CMS engineers to effectively monitor a huge number of wind turbines efficiently.
This webinar uses some recent examples and case studies to demonstrate fleet-wide condition monitoring in practice. Examples focus on main bearing and gearbox fault detection and, most importantly for the operator, methods for predicting the remaining useful life or ‘time to repair’ for key components.
View this webinar to learn:
-How condition monitoring can be effectively rolled out for large, disparate fleets of wind turbines.
-Valuable insights from recent examples in the field, particularly relating to gearbox and main bearing faults.
-Predicting ‘time to repair’ for major components.

Guest speaker presentation at 'Seminar Offshore Wind Energy' UGent – June 201...Pieter Jan Jordaens
Introduction seminar to the new study program in 'Offshore Wind Energy' organized by the Faculty of Engineering Technology of the KU Leuven and the Faculty of Engineering and Architecture of the University of Ghent (UGent). Goals of the seminar was to give an overview of the current developments in the Belgian Offshore Wind industry. This seminar gave an overview in fields such as offshore wind energy technology, grid integration & operation and maintenance. My contribution gave an overview of the current drivers, technological evolutions, ongoing market trends and technical challenges within this relative new industry. Also insights in reliability issues, risk mitigation pathways and case studies from testing and monitoring projects within OWI-Lab have been presented.

OWI-Lab develops short- and long-term monitoring solutions for offshore wind turbines. The motivation is gaining the insights that are crucial to minimize construction and installations costs of future offshore wind farms and to extend the life time of existing structures and
reduce their operation and maintenance costs. The main goal of this poster is to share the results of an extensive design verification camping. The results will allow improving current standards. Ultimately, reducing the cost of offshore wind energy.
In design verification the resonance frequencies of
the fundamental tower modes are identified using a
mobile measurement system and state-of the art
operational modal analysis (OMA) techniques. The obtained frequencies are compared with the as designed
values.
Conclusion:
Results indicate a general underestimation of the soil
stiffness. The first resonance frequency is between 5%
and 10% higher then designed. The second resonance
frequency is between 15% and 40% higher then designed. It was found that the relative difference with as designed values increased with water depth and was independent of the monopile length. Moreover it was found that the second bending mode frequencies coincided with the 6P blade passing frequencies. This can result in higher loads and therefore reduced lifetime or increased O&M costs.
CG Power Systems Belgium, a leading supplier of on- and offshore wind turbine transformers and power solutions, is using OWI-Lab's large climate chamber on a frequently basis to test and validate their products under extreme climatic conditions. Hot climate and cold start-up tests with full electrical capacity are performed on a 'time sharing' basis in the laboratory. This means CG Power Systems rents the needed test infrastructure and their own engineers perform the testing.
The large testing space makes it possible for CG Power Systems to tests and validate multiple systems in one time at the same testing conditions. Simultaneous testing can be interesting for example to benchmark results of changes in the design with different product versions of machinery in the same climatic conditions.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Testing for design validation & structural health monitoring for offshore structures
1. Test & Monitoring infrastructure OWI-lab
Testing for design validation & structural
health monitoring for offshore structures
The OWI-lab offers monitoring hardware and analysis
services for offshore testing and structural health
monitoring.
OWI-lab’s data-acquisition systems and dedicated sensors
allow identifying those parameters that are crucial:
• to minimize construction and installation costs
• to extend the lifetime of offshore structures
• to reduce operation and maintenance costs
Testing for design validation
A lot of design parameters are very difficult to predict by
numerical tools and therefore performing dedicated tests
on existing offshore structures is vital to verify the existing
design assumptions. To increase power generation
and limit weight, offshore wind turbines are becoming
structurally more flexible, thus an accurate prediction of
their dynamic behavior is mandatory. Underestimating
the stiffness and the damping of offshore structures in
the design phase inevitable results in the use of more
steel and thus higher constructions and installation costs.
Underestimating the dynamic loads or the corrosion rates
on the other hand can result in reduced lifetime of the
offshore structures and increased maintenance costs.
Structural health monitoring
A way to minimize O&M costs is early detection or even
prediction of a reduced structural integrity. Structural
health monitoring is a key-expertise within the OWIlab. Structural health monitoring involves damage
detection and characterization of structures through the
observation of the system over time using measurements
from an array of sensors. Damage in this context can be
a change in material and/or geometric properties of the
structural system. When it comes to offshore structures,
scouring, corrosion and reduction in foundation and
grout integrity over time can be problematic. Continuous
monitoring will therefore help to prevent failures and
make better decisions on when to plan maintenance
activities.

Ongoing Monitoring Campaigns at Belwind
Currently the OWI-lab is performing several monitoring campaigns
at the offshore wind farm Belwind, which consists of 55 Vestas V90
3MW wind turbines placed on monopile foundations. The wind
farm is located in the North Sea on the Bligh Bank, 46 km off the
Belgian coast.
Dynamic monitoring: consists of the continuous monitoring of
the vibration levels, resonant frequencies and damping values of the
fundamental modes of the wind turbine and its foundation structure.
Grout monitoring: consists of the continuous monitoring of the
loads taken by the grout connection and the relative displacement
between the monopile and the transition piece.
Corrosion monitoring: consists of the continuous monitoring of
the corrosion rates, corrosion potential and oxygen concentration
inside the monopile foundation.
