The present <strong>VGB</strong>-Standard covers all aspects of preservation. This standard provides operators, manufacturers<br />
and planners with a basic framework on how and to what extent the steam turbines, gas turbines and<br />
generators are to be treated.<br />
The editorial team has decided to take the steam turbine and the generator from the <strong>VGB</strong>-R <strong>11</strong>6 “Preservation<br />
of Power Plants” (republished as <strong>VGB</strong>-S-<strong>11</strong>6-00-2016-04-EN “Preservation of Power Plants”),<br />
to add a section on the gas turbine and to publish both together in this revised <strong>VGB</strong> standard “<strong>VGB</strong>-<br />
S-036-00-2017-04”.<br />
This <strong>VGB</strong>-Standard can be used analogously to protect other plant components in the power plant against<br />
corrosion. It is prepared to the best of our professional knowledge, but does not claim to be complete.<br />
By its very nature, this <strong>VGB</strong>-Standard is a recommendation and therefore cannot replace the expertise of the<br />
users.<br />
In principle, however, in addition to the recommendations and measures for protecting the assets by preservation<br />
as described below, the manufacturer’s instructions and the specifications from the operating manuals<br />
must also be observed.<br />
