PM 2<br />
“Shotton PM 2 partnership with <strong>Voith</strong><br />
has been a very successful process.<br />
In practical terms this partnership has<br />
meant that we have had a <strong>Voith</strong> start<br />
up engineer on site since the start up.<br />
This has allowed us to bring up any<br />
issues with the new equipment immediately<br />
and problems have been solved<br />
much faster. Also, issues left from the<br />
project have been followed up in a very<br />
professional way and feedback has<br />
been quick and actions have been taken<br />
to correct problems as soon as possible.<br />
We have been able to address any<br />
additional training issues immediately<br />
and this is still ongoing. <strong>Voith</strong> engineer<br />
has become an important member of<br />
our area team.”<br />

● the gap due to the missing breaker<br />
stack was closed by dryers and<br />
DuoStabilizers,<br />
● four DuoCleaners were added for the<br />
first dryer groups,<br />
● a water-jet tail cutter and<br />
● a HiVac were installed.<br />
The particular challenge was that many<br />
existing parts had to be reused and,<br />
therefore, the time frame was very tight<br />
due to extensive adaptation work.<br />
PM 2 went into operation after a short,<br />
effective start-up. The first weeks after<br />
start-up were convincing and promising.<br />

The speed distinctly exceeded the self-set<br />
target. The number of sheet breaks, the<br />
duration and number of unscheduled<br />
shutdowns showed that there was further<br />
need for optimisation.<br />
In the subsequent optimisation phase in a<br />
system partnership between UPM Shotton<br />
and <strong>Voith</strong> <strong>Paper</strong>, measures and improvements<br />
were worked out that helped<br />
PM 2 toward stable running and high efficiency<br />
within a few months.<br />
In the meantime, the specific production<br />
of PM 2 is stably above 2.00 km 2 /m/d.<br />
