Management of change in the oil and gas industry

Expecting the Unexpected

“Plans are worthless, but planning is everything” This quote from president and former general Dwight D. Eisenhower is justifiably renowned because it applies to any process complex enough that a plan might be worthwhile.

In the oil and gas industry, everything has a plan because the consequences of failure in terms of the Environment, Health and Safety (EHS) are simply too high not to have one.

These come in the form of procedures, operating parameters, processes, guidelines, layouts, instructions, and even detailed workflows supported by EHS software. But as noted by the general, every plan no matter how well made eventually runs into something unanticipated.

What Causes a Change in Plans?

During normal operations, most processes are reasonably routine, have a high level of repeatability, and can be scheduled or reasonably predicted.

However, some things are not within the scope of control – for example, if raw materials fail to arrive as scheduled and the plant has to slow or change production.

Any changes, even those that are expected or intended can create a disruptive knock-off effect on standardized processes. These most often come in the form of disruptions to normal processes caused by:

  • Scheduled repairs
  • Maintenance and testing
  • Turnarounds
  • Upgrading or replacing equipment
  • Changes in staffing levels or of specific staff members

Examples of consequences due to the changes can include:


  • Changes in the projected start and stop time of the disruption
  • Changes in available service and maintenance equipment or availability
  • Changes in the scope of work due to the discovery of new or different problems than originally expected
  • Unexpected repairs or breakdowns
  • Time or location critical disruptions to other parts of the facility during planned work
  • Crew or shift changes

Why is Managing Change so Critical?

Processes and equipment are designed to operate under a range of set conditions that are assumed to stay the same. During the sorts of disruptions listed above, many of the assumptions go out the window, and procedures risk not operating at full capacity.

Recognizing when a situation has changed sufficiently to require a management process and what changes should take place are critical to avoid future or immediate EHS issues.

Oil and Gas Safety

Gaps in Change Management

In analyses by the chemical safety board, OSHA, state safety councils, and other investigators break down the two key areas of communication, and crew or shift changes.

Changes or irregularities are often identified reasonably well by the people who find them initially, but the information is not always passed on to all stakeholders.

Word of mouth and person to person reminders are not a replacement for alerting the crew as a whole and documenting the new situation for future use so that everyone involved in the work is aware.

Alternately it may be well documented but communicated incompletely or without sufficient urgency or attention drawn to the most critical points to ensure that everyone understands how things have changed and why it matters.

MOC Process for Oil and Gas

Bridging the Gaps

Consistent, repeatable, reliable, and easy to use systems for tracking and transmitting information in the MOC process is critical for success.

  • Consistent: So that it is clear to all users what to do and what not to do in a MOC situation
  • Repeatable: The same processes for MOC should be used so that it is familiar (even if the changes to be communicated and documented are not)
  • Reliable: So that it is easily available when changes are found and when they must be understood by parties later

Gaps in MOC processes and communication occur when it is easy to continue due to the existing processes and procedures for documenting and communicating.

They will continue to exist unless the solutions that close the gap are consistent, repeatable, reliable, and easy to use.

This is not because people lack the will or desire to do the right thing but simply that getting MOC right is one of many competing priorities for the limited time allotted.


Schedules change, key people may have to switch their focus to other tasks, employees move. Proper documentation, communication, and workflows are critical to avoid disruptions.

Having a well-organized MOC system in a continuously operating plant or facility is critical to ensure swift, safe, and effective completion of the work done.
