Wärtsilä

A New Era of Measurement with Metronor

Wärtsilä’s significant position in the global market can be explained by the fact that 1% of the world’s energy is
produced in Wärtsilä’s power plants, and that every third ship on the high seas is fuelled by Wärtsilä power.
Noteworthy is also Wärtsilä’s service program. For example, every second ship worldwide is serviced by Wärtsilä.
Wärtsilä’s success is reliant upon its ability to constantly innovate and develop new products. With the help of a
Metronor DUO measuring system, they are now able to do so with increased efficiency and quality assurance.

Large Volume Inspection - A Key Factor t
Contributing to Wärtsilä’s Success

Development engineer Tero Kujamäki states that quality is
one of the factors key to Wärtsilä’s success. “After all, Wärtsilä
works in sectors which require absolute performance. For
example, power plants need to produce energy every single
hour, and ocean ships cannot stop due to engine failures.”

“Metronor is also used in the production line where it
determines the quality of the end product, for example
measuring hole patterns on different levels. These were
time-consuming measurements that also used to be difficult
to perform using traditional methods. By using the Metronor
system, we are able to measure big blocks with high accuracy as
well as save valuable time”, states Kujamäki.

t Effective Tools Equals Multiple Savings
Kujamäki is also impressed with Metronor’s inspection reports.
“We are able to take advantage of Metronor’s reports and the
clarity of the 3D verification. Previously, the results of
measurements needed to be recorded manually which resulted
in different measurement protocols. After purchasing Metronor,
results can be understood at a single glance and color
coordination means that everyone in the organization can
understand the results. In the long run, we believe that
Metronor has helped us to achieve multiple savings. First of all,
inspection times have been reduced significantly.” Kujamäki also
recognizes the benefits of process optimization, material savings
as well as reduced machining bring to the organization.
To ensure efficiency and quality, Wärtsilä acquired a Metronor
DUO measuring system equipped with 3 cameras, LED-pad and
LED-kit as well as PowerINSPECT inspection software. The
Metronor system is already delivering great benefits to the
Finnish giant. “Before purchasing Metronor, scanning inside
large engine blocks was a laborious combination of laser
measurement and traditional instruments. Metronor’s
efficiency and clarity enhance the manufacturing process with
additional speed”, says Kujamäki.
“Metronor is for instance used for casting block measurements.
We do quality checks on subcontractors’ casting blocks on
arrival so we can determine if they are acceptable for
machining. Metronor is very suitable for this type of
application. It is commonly known in the industry that poor
stock geometry can lead to scrapping or extensive re-work. If
stock excess is not accurately recognized, extensive and
unproductive ’cutting air’ may well be the result. We utilize
Metronor diversely for measuring excess material and
alignment of the casting block on the machine and thereby
significantly reducing time spent and general costs”, he says.
