The safe operation and high level of availability of turbine plants place high demands on the quality and cleanliness of the lubricating and control oil used.

By collecting and evaluating the vast experience gained during the operation, installation, modification and revision of gas and steam turbine oil plants and incorporating them into this VGB-Standard, the intention is to contribute to the operational safety and availability of the plants and to avoid errors when flushing oil systems. The measures to be taken in respect of planning, ordering, installing, modifying and revising turbine oil systems should be coordinated intelligently.

Given the large number of oil system designs, it is not possible to cover every detail. These instructions for oil flushing can therefore only provide a framework for those criteria which must be followed. Partners concerned may use them in whole or in part and this must be agreed between the parties in each individual case.
