Abstract – In many cases, Management of Change (MOC) programs are overly burdensome and could be ineffective. The application of MOC at the early stage of process design is simpler and easier compare to at later design stages. MOC methodology should be applied to engineering design deviations and variances, as well as to preplanned changes. An improper relief header design can lead to outcomes that pose a significant threat to the operators and the equipments in the immediate vicinity of the failure location.
This paper highlights the application of MOC during engineering design and construction, the use of available technology to support MOC, and how MOC application helps to execute the revised design. The improper design of relief header is also presented as the case study.

Keywords: management of change (MOC), change, engineering design deviation, relief header design, revised design

1. Change and Management of Change

First introduced formally by nuclear power industry, Management of change (MOC) has been quickly spread to the defense energy [1]. The meaning of MOC refers to the making of changes in a planned and managed or systematic fashion. The intention of MOC is to implement new methods and systems more effectively in an ongoing organization. The changes to be managed lie within and are controlled by organization. Hence, the second meaning of managing change is the response to changes over which the organization exercise little or no control.

MOC procedures have stolen attention due to the introduction of requirements within the new OSHA 1992 and EPA 1998 process safety management regulations in US. Recently, ISO 9000 quality initiatives have provided future significance to the need for process change control management. While many firms applied MOC only to equipment and field operational procedures changes, some big chemicals producers are also applied MOC on personnel.
