In recent years OPENpredictor
The best support a company,
busy in consolidating its market
position, can get is when
customers actively recommend
its products and services.
In this issue of Dynamics News
we are happy to share two
such examples with you from
different corners of the world.
Electricité de France, the
world’s largest power producer,
have now actively worked with
Rovsing Dynamics since 2004
and applied OPENpredictor on
many of their plants.
EDF’s engineering unit have
implemented an e-monitoring
set-up, and uses information
from the condition monitoring
system to provide operational
support and recommend future
maintenance activities, based
on the anticipated machine
degradation. The concept has
so far proven well.
Equally important statements
were given as conclusion
on an appraisal meeting in
the Guangdong Province in
China, where highly esteemed
Chinese professors reviewed
the OPENpredictor system
recently commissioned on
the Meixian power plant. We
were happy to learn that the
evaluating expert team issued
a positive statement concluding
that “All in all, OPENpredictor
is an advanced system in
the world marketing place,
deserved to be adopted by our
domestic establishments.”
The below update on our
efforts in the maritime industry
includes several new systems
on order and a pending marine
approval of our condition
monitoring system.
We are happy to share the
news with you – enjoy your
reading.
Thea Larsen
CEO
has found its way to more
and more applications in the
maritime industry. Owners of
container ships, oil tankers,
ferries and supply vessels have
chosen the system to monitor
e.g. bearings and other critical
components of the main engine,
turbochargers and thrusters
as part of a condition based
maintenance strategy and to
avoid open-up inspections.
Therefore, Rovsing Dynamics
is in the process of having
Bureau Veritas type approve
the OPENpredictor system for
online condition monitoring of
bearing wear and other faults
on vessel machinery.

REMOTE MONITORING OF
EDF’S THERMAL & HYDRO POWER PLANTS
By Jean-Christophe Licheron, EDF
specialized organization, DTG
is able to assist the group’s
power plants in anticipating
future degradation of monitored
machines and thus to execute
condition based maintenance.
interrupting their operation
• monitor the development
of specific phenomena and
anticipate their further
development until the next
planned maintenance stop.
Jean-Christophe Licheron
from the DTG engineering
unit of Electricité De France
(EDF), explains how they use
OPENpredictor for remote
condition monitoring of
power plants in France and
abroad.
DTG is an engineering unit
within the EDF Group, which
provides support for the
group’s electricity producing
operations (hydraulic, nuclear
and thermal power plants) and
also for external electricity
operators, local authorities
and government organizations
in France and abroad. The
team’s main tasks cover three
areas: measurements, diagnosis
and expert assistance. DTG
is specialized in the fields of
hydro-meteorological forecasts,
monitoring of engineering
works, thermodynamic
performance, electric materials,
mechanical behaviour,
environment and topography.
Besides providing operational
support, DTG also contributes
to three other essential areas
related to power production:
safety, productivity and
environment.
E-monitoring
supports operations
E-monitoring is a special
condition monitoring service
offered by DTG. Thanks
to dedicated tools and a
In 2004, EDF’s research and
development organization chose
the OPENpredictor system for
monitoring of the vibrations of
the major rotating machinery
at various power stations.
The first installations of the
OPENpredictor system were
carried out on gas turbines
(Norte Fluminense in Brazil
and Saltillo in Mexico) and on
steam turbines and other large
components such as pumps and
fans on the power stations of
Suez and Port Saïd in Egypt.
Remote diagnosis
Since 2005, DTG has also
acquired several portable
OPENpredictor condition
monitoring systems, used on
EDF’s power stations in France.
These mobile systems, installed
temporarily at different sites,
make it possible to
• identify certain nonreproducible
phenomena
• carry out vibration monitoring
on key components without
The cooperation and regular
interaction between EDF DTG
and Rovsing Dynamics allow a
continuous development and
adaptation of the monitoring
tools for continuous progress
in the area of detecting and
predicting faults on rotating
machinery.
Support for
maintenance planning
The experience gained these
recent years shows that the
OPENpredictor system fulfils
EDF’s needs for vibration
monitoring of the rotating
machinery of its power plants.
Moreover, the possibility
of installing the system on
a permanent as well as a
temporary basis, using portable
systems, makes it possible
to utilize these systems on
a wide variety of machinery
components on hydro, thermal
and nuclear power plants. On
the basis of measurement data
transmitted automatically and
daily to DTG, regular trend
analyses and alarms emitted by
the OPENpredictor systems
enable DTG’s expert team to
assist the group’s power plant
operators in their planning of
future maintenance activities.

e-monitoring staff to provide the plant operators’ with remote
expert diagnostic support

The appraisal seminar was hosted
by the Meixian Power Plant in
the Guangdong province, the
first to install OPENpredictor
in China. Here, a plant engineer
demonstrated to the experts
how the system is used for
online condition monitoring of a
steam turbine generator.
With insight into the practical
usage of the system, the
expert team was presented
with the scientific principles,
mathematical models and
analysis tools behind the
condition monitoring technology
and its patented automatic fault
detection (AutoDiagnosis). To
illustrate this, Rovsing Dynamics’
Technical Director Ole Doessing
used live data from the system

CONDITION BASED MAINTENANCE SEMINAR IN ABU DHABI
On February 5, Rovsing
Dynamics hosted a seminar in
Abu Dhabi in the United Arab
Emirates together with our
local representative, Nama
Development.
The purpose of the seminar was
to share OPENpredictor case
studies and prove the value of
the system to operations and
maintenance managers from
the oil & gas and the water &
power industries in the region.
They use OPENpredictor
as a predictive maintenance
information system to monitor
critical recirculation pumps
and fans at the al Taweelah
desalination and power plant
located between Abu Dhabi and
Dubai. Mr. Samson explained
how the system is used to assist
the plant’s condition based
maintenance strategy.
OPENpredictor in
the oil & gas industry
The seminar also included
a presentation on how
OPENpredictor on-line
condition, performance and
reliability monitoring of gas
turbines and compressors on
gas compression stations has
significantly improved the
reliability and availability of
oil and gas production. The
fact that the investment in
OPENpredictor typically pays
back itself within less than one
year, proves the value of this
proactive approach.
