In order to start up, maintain or repair plants, it is necessary to move the plant up or down in a certain order. Especially at shutdown, both mechanical and electrical measures must be taken.
To allow repairs to take place at different locations and objects, units are dynamically provided for maintenance and activation. The objects within such units always form the basis for activation and maintenance work.
For the maintenance of the plant, all measures are usually performed during operation.
For this reason, the releases for a planned shutdown or revision are predefined. Since measures in the realease can be safety-relevant, this procedure is also part of a HAZOP consideration. This connection must be considered as mandatory!
For the HAZOP process PLM-PLANET can be supplemented with further modules.
