Overhaul and Maintenance in Refineries

An oil refinery, also known as a petroleum refinery, is a manufacturing facility that converts crude oil into products including petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel, and fuel oils. Overhaul is a frequently used word in industry and especially in maintenance. By definition, an overhaul means a thorough checking and performing the required repairs or reparations of all machinery, equipment and parts in an industrial unit. We use the term frequency in complex Industries including oil production industry, aviation industry, ships and vessels, trains, airplanes , etc.

There are a large number of installations, equipment and machinery in the refinery that are always working to refine the crude oil and produce petroleum products.

Overhaul in oil refining companies is a total checking of installations , machines and equipment and doing needed repairs. For instance, it includes distillation columns, atmospheric towers, heat-exchangers, pumps, compressors, vessels, tubes and so on.

State of Overhaul Maintenance in Oil Refining companies

State of the art overhauls in Oil refining companies include a planned Shutdown. It provides a suitable condition for implement a special maintenance project which lasts up to several weeks!

It is a comprehensive shutdown of the operational unit and extends to the whole processes to check or repair all installations and machinery. This means, stopping all production processes in that unit. Subsequently, it will change the overall production plan of the refinery.

Production plans are very daily-variable in oil refineries; Overhaul project manager should use a suitable methodology to be able to make timely, fast, evaluated and agile changes. It means that overhaul project needs a high level of agility to make more consistency with production plans.

What’s the problem?

Currently, overhaul projects are managed by Waterfall method in some companies. In most refineries (specially in Third-World countries), despite the agility of production projects, unfortunately maintenance and overhaul projects are Waterfall type.

 Waterfall Model methodology is a Liner Sequential Life Cycle Model. It followed in the sequential order.

 Agile methodology is a practice that helps continuous iteration of development of overhaul results and testing in the repairs process. In this model, development and testing activities are concurrent, against the Waterfall model. Agile method allows more communication between Stakeholders, overhaul team members, overhaul manager, and product owner.

The problems seen in this method of overhaul can be discussed in two general areas:

1- Lack of flexibility in the Waterfall overhaul project to make changes during execution:

Overhaul project team only moves to next phase of testing or repairing if the previous step completed successfully because Waterfall is a linear and sequential approach.

2- Imposing more and newer costs in case of change in the time of major repairs by Waterfall method :

Although there are several kinds of costs in each project for instance, material supplying and human salaries but the main cost is production reducing during the overhaul implementation. In order to decrease incurring final overhaul costs, we should use an appropriate project management method to make more coordination with the production management plans.

Which Methodology in Refineries? (Waterfall or Agile?)

There are some advantages and disadvantages for using Waterfall or Agile methodology to implement the overhaul.

By Waterfall methodology we can complete the overhaul project almost on predicted time. There is a Straightforward planning and designing due to the agreement on deliverables at the start of the overhaul project. Dedicated resources can work in parallel for their specific tasks. It also is more suitable for material supplying costs or human costs (because there are no additional costs related to iterative tasks or development). There are also clear measurements of progress. perhaps, it is better design with whole-system approach.

Currently, in most refineries (specially in Third-World countries), despite the agility of production projects, unfortunately maintenance and overhaul projects are Waterfall type. Although overhaul projects in the oil industry require large budgets and the number of team members in each project is large, but it seems necessary to change the approach of projects from Waterfall to Agile Project Management.

Agile methodology has more flexibility to receive feedbacks and do repair improvements by iterative tasks. so, Agile Project Management in Refineries is an important step in this direction. Although it may increase the duration of some sub-projects or tasks but there are some strategic reasons that can motivate project managers to implement the overhaul project by Agile methodology!

Why Agile Project Management in Refineries

Agile Project Management is more flexible than Waterfall. By an Agile method, the overhaul project can adjust with the unpredicted situations for instance, ordered changings about the start date of project implementation or providing new requests during implementation.

Sometimes, Stakeholders (which here are the Product Operations Management team) or Product Owner (here, the Technical Inspection and Quality Control office) requests some fundamental changes; They also may order some additional requests during the tasks or sub-projects! In this situations, Waterfall management method cannot make rapid changes or it may be very costly but Agile methodology can do it.

In addition, sometimes for various reasons, the time of the overhaul project implementation may temporarily be canceled or postponed to the future due to the Government orders! So, by Agile Project Management we can prevent increasing the high-risk costs (particularly about the goods and materials supply costs, warehousing costs).

Therefore, creating the maximum coordination between the overhaul planning and production plans highlights the need for agility of overhaul project. Agile methodology is needed to make an ability for adapting to unforeseen and instantaneous conditions.

Obviously, reducing the total cost of carrying out an overhaul project requires performing the project within an optimal range and it needs having a good appropriateness and coordination with the production plans and company policies. There are some parameters which causes the production plans and company policies to be so daily variable. So, an agile overhaul can make a suitable adjustment with these variable situations. But, what are parameters exactly?

Parameters which cause the daily-variable situations:

As mentioned, there are some factors which cause the daily-variable situations in a refinery. The production plans change frequently due to their high dependence on these various parameters:

Parameters which cause the daily-variable situations:

1-Orders issued by the Government: 

General policies announced by the Government is one of the most important parameter that change production plans daily. The Government orders depends on some variables for instance:

  • Volume of daily total petroleum producing in country.
  • Country’s daily requirement for each product.
  • Keeping a balance between the total daily volume Crude Oil extraction in the country and the daily consumption of crude oil by Refining companies.
  • Maintaining the proportions set in crude oil exports and also export and import of petroleum products.
  • General policies about storage capacity of crude oil and also petroleum products affected by forecasting the need in the coming months.
  • caution in all estimations and calculations of production and consumption volumes of crude oil and petroleum products.
  • Considering the different Geo-political situations in the regional-international dimension in the future.

2- Environmental phenomena and conditions: 

  • Some environmental phenomenal such as air pollution in the region that leads to the need to reduce production processes in some industries- Refineries, for example.
  • Seasonal condition of air temperature is also another environmental phenomenal element which affects the decisions. As the weather cools, the demand for petroleum products increases; With the arrival of the warm seasons, the demand for petroleum products decreases. The variability of demands directly affects the production and supply of petroleum products. So, this is another factor in the variability of production programs.

3-Routine and daily changes of some operating conditions in refineries:

  • Daily variety of empty capacities in the storage tanks in the oil refineries and Oil Products Distribution Companies.
  • Occurrence of some unforeseen conditions in case of failure of some key machines and equipment without replacement (pumps, compressors, etc.).

Agile Overhaul Implementation Steps 

Using agile Overhaul to solve maintenance challenges in refineries will require organizations to rethink traditional ways of working and leverage new and enhanced management methodologies capabilities. In author opinion , this process should incorporate six elements. 

1- Integrated dynamic planning

By an integrated dynamic planning, an overhaul project manager can use scenario analysis and plan manipulation to optimize sub-projects and tasks. He can do it based on the received datasets from Product Management department of refinery and logistics constraints across the overhaul value chain and life cycle.

By only targeting critical areas for checking of installations , machines and equipment and doing required repairs , much of the overhaul implementation can be consistent across a given field area. It can makes results delivery execution more iterative and efficient as there are fewer changes occurring.

2- Data-Driven, Analytics-led design optimization

Cognitive analytics and machine learning provide capabilities to more quickly identify variable factors -as mentioned- which most affect overhaul planning. Thus it helps avoid decreasing refinery products during the overhaul implementation -as opportunity cost of developing repairs in overhaul- with optimal planning.

Overhaul planning team members should:

  1. Apply machine learning to optimized planning for smarter targeted management.
  2. Pushing the performance testing repaired machineries .
  3. Enabling more consistent aspects of overhaul planning in the agile project delivery approach.

3- Digitalization

Decluttering or eliminating manual and time-intensive processes can free up engineers and field leadership to focus on more value-added activities.

Digitizing workflows can enable process automation, create faster and easier links across tasks, and improve collaboration by bringing the right information to the right people at the right time. This combination can improve efficiency, ease scalability, and increase standardization across workflows.

4- Real-time drilling & completion (D&C) monitoring & control

Using remote operation centers (ROC) to conduct real-time monitoring and control of D&C (foe example, HSE principles training, industrial discipline, teamwork principles, new specialized repair skills, etc.). It helps workers to more rapidly learn before overhaul and also react throughout the overhaul results delivery process.

This institutionalized approach to real-time data and analytics can:

  • Improve good execution and good results.
  • Apply learning and experiences to the next overhaul in the refinery.
  • Improve resource utilization and knowledge transfer to the future workforce.

5- Continuous and automated feedback loop

Machine learning can help project management team better determine the impact of good planning on good performance during the early life of overhaul.

Digital facilities can also enable project controllers to :

  • more quickly uncover key findings.
  • Automate sharing with relevant engineers and stakeholders.
  • Feed information back into an integrated, dynamic plan that maximizes good and field potential.

6- Integrated Overhaul team & Refining Product Management department platforms

It’s time for the traditional interactional relationship between Refining Product Management and project management team members evolve to meet the new realities of pace and scale in unconventional challenges.

As planning team members establish integrated data platforms that strengthen cross-functional collaboration, there is significant value potential in extending this to the work space to create a more transparent and efficient operating model. This can make value creation a shared goal.

1- Satisfactions.

The satisfaction of the Stakeholders and Product Owner:

Agile overhaul can satisfy Stakeholders (which here are the Product
Operations Management team) by accelerating the completion of the project and
the early delivery of the Production operational unit.

Also it can satisfy the Product Owner (which here is the Technical
Inspection and Quality Control office) through iterative and continuous
delivery execution results of sub-projects or tasks.

They are happier when they receive results at regular intervals than they
wait for a long time to complete the main project , while in Waterfall methods,
they have to wait until the end of the project and wait for the final whole
project results! (The first principle of The Twelve Agile Manifesto
Principles
.)

2- Accommodate changes and Frequent
deliveries.

Accommodate changing requirements and Frequent deliveries throughout the
development process (according to the request of the stakeholders):

The ability to avoid delays when a requirement or feature request changes;
While in the Waterfall method, there is no such flexibility during the
implementation phase of project and all sub-projects and tasks must be
performed exactly according to the predefined plans! (The second and
third principles of The Twelve Agile Manifesto Principles
.)

3- Collaborations.

The best Collaboration between the Overhaul Stakeholders and technical team
throughout the project:

Better decisions are made when the Stakeholders and technical team are
aligned. (The fourth principle of The Twelve Agile Manifesto Principles).

4- Interactions.

Enable face-to-face interactions – Communication while in the Waterfall
method, such a feature is rarely possible! (The sixth principle of The
Twelve Agile Manifesto Principles
.)

5- Pace.

Supporting a consistent Technical and Maintenance pace :

Teams establish a repeatable and maintainable speed at which they can
deliver working repaired equipment and Machines, and they repeat it with each
release; again, in the Waterfall method, such a feature is rarely possible! (The
eighth principle of The Twelve Agile Manifesto Principles
.)

6- Agility.

Attention to details of right technical skills and good implementations:

It enhances agility and ensures the team can maintain the pace, constantly improve
the Results
and sustain change. so, this is possible in a Agile Overhaul
project managing. (The ninth principle of The Twelve Agile Manifesto
Principles
.)

7- Self-organization & Motivation.

Agile Maintenance implementation leads to making Self-organizing, Skilled
and motivated team members that encourage great planning, requirements, and
implementations:

So, regular communications with other team members and sharing ideas that
deliver quality results will take place unlike the waterfall method, which does
not give team members a chance at such opportunities! (The eleventh
principle of The Twelve Agile Manifesto Principles
.)

8- Efficiently.

Finally, receiving regular feedback and reflections will help team members
work more efficiently! (The twelfth principle of The Twelve Agile Manifesto
Principles
.)

Conclusion  

Agile Project Management is a new approach in overhaul of oil refinery
units. Overhaul project managers can use this method instead of Waterfall
method to reach some better results.

Overhaul implementation in an operational unit of refinery stops production
processes in that unit. Subsequently, it will change the overall production plan
of the refinery. so, the overhaul project should adjust with the production
plans. On the other hand, there are some factors which cause production plans
encounter with unpredictable situations and change frequently. So, Agile
Project Management has more flexibility than Waterfall to adjust with these
variable and unforeseen situations.

In addition, by Agile methodology changing requirements and frequent
deliveries throughout the development process are reachable. It also will make
more interactions and collaborations and team members will have more pace,
self-organization & motivation and it leads to increase efficiently.

Finally, all above results make reduction of total cost of carrying out the
overhaul project. You may get further details about the implementation and
