Management of Change MOC

They are many types of MOC checklists currently in use in the industry. The following key aspects are used in developing robust MOC procedure (CCPS, 2007)  

PSSR (conducted before the modifications are commissioned) is also a part of the MOC procedure. Any new items identified during the PSSR may require further rounds of review and approvals by the reviewers. Completed MOC is an important part of process safety management it needs to be filed in the facility s process safety and project files, and stored for the lifetime of plant operations. These forms are required for future MOC audit and also are useful during future PHA studies. CCPS (1995) and CCPS (2007) presented MOC process and useful check lists. Note that a proper MOC procedure could have avoided the Flixborough incident outlined in Section 3.2 (CCPS, 2007). 

This chapter presented a comprehensive overview of all process safety aspects applicable for revamp projects. It provides a quick reference for practicing engineers and also students. Note the following key points for achieving sustainable revamps. 

Proper application of hazard analysis methods and PHA (What-if, HAZOP, FMEA) in pre-FEED and FEED stages is very important to develop safer and cost-effective designs 

Plot plan, layout, area classification, pressure relief and fire safety design reviews are crucial to make revamp projects safer

On the other hand, there are a number of elements of fire prevention that overlap with elements of other programs. For example. Incident Investigation, Management of Change (MOC), Process Safety Information (PSI), and Process Hazard Analysis (PHA) input required for fire prevention can be derived from these same elements of the Process Safety Management (PSM) program. 

It is important to document the assumptions used in determining the inventories for the FHA. The inventory list should be maintained throughout the lifecycle of the facility by the Management of Change (MOC) process.

The safety impact of design and construction changes to a project performed after the final HAZOP or What-If reviews and prior to commissioning are identified as part of the facility Pre-Startup-Safety-Review (PSSR) and Management of Change (MOC) procedures.
