8.2 Group
Your reliable partner in renewable energies
– successful now for more than 15 years!
In October 1995 the success story of the 8.2 Consulting began with the foundation
of the first 8.2 Engineering Office in Süderdeich by Manfred Lührs. Thus, he is
one of the pioneers in the wind energy industry. Since then the 8.2 Group has been
growing constantly in the national as well as international market. Today with more
than 15,000 inspections carried out all over the world and with 24 independent
offices, the 8.2 Group with more than 150 employees is known as one of the
leading specialists worldwide for the different sectors of renewable energies.
In addition to technical inspections of wind turbines, photovoltaic and biomass/
biogas plants, the 8.2 Group also performs comprehensive consulting services
which are facilitated by the specialist knowledge of the 8.2 Group members in subjects
such as glass fibre-reinforced composites, vibration analysis, video endoscopy,
Condition Monitoring, rotor blade inspection by rope access technique as well as
foundation control.
Our active way of knowledge management will be your profit
The close cooperation of all 8.2 offices as well as the exchange of experience and
information on a regular basis supports a constant transfer of valuable knowledge.
Thus, every 8.2 expert is able to access the Group’s complete knowledge which
is being improved and updated continuously by additional and regular training
programs in our 8.2 AcAdemy. The technical knowledge of the 8.2 experts is always
on an up to date level due to their active work in certification bodies, committees,
advisory boards and quality initiatives; moreover, our experts are working actively
for the development of norms, basic principles and inspection methods.
You as our customer will profit from this unique professional background based
on our advanced knowledge and high quality level of work.

Offline Vibration Measurement and Analysis
Offline - Vibration Analysis:
How to detect problems in the drive train
With the experience resulting from 2,000 Offline vibration analyses on
300 kW – 6 MW wind turbines the 8.2 Monitoring GmbH inspects drive trains
with the help of highly efficient vibration analysis. In order to evaluate the results,
the experts use their own software VibraLyzeTM Pro which corresponds even to
the critical requirements of German insurance companies.
Main characteristics of the 8.2 Vibration Analyses:
» extremely high sampling rate up to 52 kHz
» long term recording up to 300 seconds
» parallel measuring on 4/8 channels with 16 different positions of the sensor
» recording of rotational speed along with vibration signals
» standardization of rotational speed and order analysis
Apart from the optical and acoustical examination during technical inspections
vibration analyses offer the possibility to identify irregularities on the drive train
(shafts, bearings, gear stages). We are able to provide 7 service teams for measurement
in order to work efficiently even in larger wind parks.
Our significant reports with procedure recommendations will provide more
security for you and appropriate margin for the planning of maintenance works.

Video Endoscopy:
For early detection of defects in components
Since 2004 the 8.2 Group has performed more than 1,000 inspections by video
endoscopy – a visual examination with the help of a video camera. There is no other
technique which provides a quick, secure and reliable optical examination of difficult
to access areas as for example cavities or internal components of a machine.
Apart from being able to visualize the internal structure of objects the video endos-
copy offers the possibility to assess the condition of objects as far as possible defects
are concerned. Costly stand still periods of wind turbines will be reduced if defects
of components are detected during an early stage.
Within wind turbines the video endoscopy is mainly used for the inspection
of gear boxes. However, the 8.2 experts use the video endoscopy also for the
inspection and assessment of generators, pressure chambers of rotor blades
and other components.
Thermography:
Easy detection of problems with cable connections
Wind Energy
Special Discipline
During the inspection of the electrics of wind turbines or photovoltaic plants the
8.2 Group uses the technology of thermography. Thus, problems caused by cable
connections installed in an in appropriate way can be detected more easily.
On- & Offshore Rotor Blade Inspection:
Experienced specialists
During factory and guarantee acceptance tests, repair monitoring as well as
recurrent inspections, the 8.2 Group has already inspected more than 3,000 sets
of rotor blades. Due to the vast know-how concerning the use of fibre-reinforced
composites the 8.2 Group is considered a specialist in this sector.
Rotor blades are inspected by:
» rope access technique (for all heights)
» platform (as far as available and as far as possible
according to respective hub heights)

Construction Surveillance:
Evaluation and Expertise Reports
During the surveillance and evaluation of wind turbine foundations 8.2 experts
inspect the conditions of foundations and determine existing damage. The 8.2
support contains optimized construction consulting during design and construction
of wind turbine foundations.
8.2 helps to prevent damage by continuous monitoring and Quality Assurance during
the construction phases via the inspection of access roads, foundations and towers.
We develop refurbishment concepts to eliminate damage at wind turbine foundations.
Measurement of Unfixed Tower-Restraint
The measurement of unfixed tower-restraint at foundations is the most important
initial point for the evaluation and the planning of refurbishment. This measurement
method is to be used to check the fixed anchorage of the tower in the foundation.
One advantage of this measurement method is that the elastic elongation
of towers can be detected and eliminated. The output provides exact results.

Special Discipline
Quality Assurance and Control of Foundation Construction,
Cable Works and Access Roads:
With several years of professional experience our 8.2 team is now working actively
in this area and in the control of construction works with foundation as well as the
control of providing cable and access roads. The on-site building control is part
of quality assurance, thus guaranteeing an operation without problems until the
erection of the wind turbine and resulting in a minimum of standstill times during
transport and erection of the wind turbine.

– all in one!
Technical Inspections
Working as independent experts the 8.2 team performs technical inspections of
your photovoltaic plant and clarifies proficiently any technical problem. However,
the actual work already begins with the contract control right before the erection
of the photovoltaic plant. All requirements of the building permit will be checked
with regards to their respective fulfilment and the delivery of the plant according
to contract will be controlled. The results of any possible quality defect can thus
be reduced to a minimum due to continuous construction monitoring and factory
acceptance tests of components.
