Advancing the Plant Shutdown

Generally, considerable advance planning is necessary for carrying out jobs during a plant shutdown. Many spares have to be procured, extra manpower is to be arranged, some outside parties are to be engaged, and certain heavy-duty machines are to be hired (on a per hour basis at high rates usually). 

However, the plant may have to be shutdown a few days earlier in certain circumstances  

Power supply has broken down or has become erratic due to any problem in the supply grid  

Accidental deactivation of catalyst or damage to a key equipment (leak of boiler tubes) is creating environmental pollution or a heavy drop in process efficiency.
