Change Analysis

As you know, change is continuous on an oil and gas wellsite. Change analysis is simply the analysis of the management of change (MOC), conducted by competent persons, to make sure that change on the wellsite does not introduce new hazards or unsafe procedures in the work environment.

Change is continuous on the wellsite.

A designated person should analyze how changes on the wellsite can affect equipment, processes, and materials for hazards and potential hazards. Findings should be documented and plans developed to minimize or design out the new hazards.

Changes in the following general categories need to be reviewed:

  • wellsite layout
  • materials
  • process technology
  • equipment

All areas on the worksite should be analyzed to more specifically analyze how changes to the wellsite layout, materials, processes and equipment, affect the work being conducted.

Analyze each of the following areas as part of the baseline survey:

  • site entrance and traffic routes/surfaces
  • covered walkways
  • protection from falling objects
  • danger areas
  • storage and personnel areas
  • hazardous materials/dangerous goods
  • barriers and fences
  • loading and unloading areas
  • bays and ramps
  • working, slopes for excavators, dump trucks etc.
  • safety signage
  • protection of pedestrians
  • site security
  • housekeeping and cleanliness
