The Usage of PID

"&* is implementation of process system conceptual

"&* is a more complete-"* with control system .specification/!etails !ata

"&* is input (upstream !ocument) for otherengineering/procurement/construction !isciplines(material take off equipment, piping,instruments,scope of supply checking,construction

stages,commissioning/start up sequences)

"&* is the !ata source for analysis of ha0ar!ousoperation (1#23"), risk mitigation of operation
