Challenges for Customers

As global energy demands increase, plants have a mission to achieve high-quality project execution, plant operations, and maintenance.

However, companies are increasingly constrained by personnel issues, budgets, and shrinking timetables. Aside from grassroots construction activity in emerging markets, companies are also faced with the task of executing multiple projects simultaneously in disparate geographic regions.

Our Solutions

Increasingly, companies depend on Yokogawa to take on the role of main automation contractor, owning responsibility over all automation-related aspects of the project with our Innovative MAC Services (yi-MAC) method of project execution.

Yokogawa provides highly qualified and well-resourced control systems specialists to engineer, supply/procure and manage instrumentation, control systems, safety instrumented systems, and associated interfaces for all project components and facilities.


Customer Benefits

Yokogawa as a MAC assumes responsibility over all automation-related phases of the project.

The Yokogawa MAC team constructs the most suitable project organization and works directly with the end users, EPCs, and third parties. With the MAC approach of dealing with Yokogawa directly, it isn't necessary for customers to manage various automation suppliers.

Instead, customers can derive cost savings, risk mitigation, and shorter delivery times, etc. With our global engineering network and resources, Yokogawa can safely and efficiently execute projects, and then provide optimal operations support over the entire plant lifecycle.

Traditional Approach vs MAC Approach

Compared to a traditional approach, Yokogawa MAC enables drastic costs saving for the overall project.

Many of the world's leading end users, particularly in the process industries, are applying the MAC approach to their entire capital project. The MAC approach can result in project cost savings of up to 30% against a traditional approach. Costs are reduced in nearly all phases of the project, since automation suppliers are encouraged to consolidate industry and application expertise to execute projects in a consistent manner. This means developing practices and procedures that are standard and can be applied across multiple projects to reduce costs.

Yokogawa MAC Project Organization


  • 16,000 FOUNDATION Fieldbus devices
  • Main Automation Contractor (MAC)
  • DCS anywhere concept integration with site SAP system
  • Long term maintenance contract
  • Sustainable development
  • As the main automation contractor (MAC) for this plant construction project, Yokogawa Brazil engineered, installed, and commissioned an integrated control and instrumentation solution
  • Yokogawa Brazil completed the commissioning of these systems ahead of schedule and the production of green polymer was started just one week later

Nederlandse Aardolie Maatschappij (NAM) is the Netherlands' largest natural gas producer. In addition to onshore fields, NAM operates manned platforms and four unmanned monotowers in 19 offshore locations. These connect to a pipeline network that comes ashore at Den Helder. 

  • Yokogawa receives award for hot cutover of BP Sharjah plant DCS.
  • Yokogawa was selected by BP as main automation contractor (MAC) for a project to replace the Sharjah plant's existing legacy DCS with Yokogawa CENTUM VP.

Agile Project Execution is YOKOGAWA's methodology to execute all projects in a cost efficient way by removing waste.

With the release of the new CENTUM VP R6, a solution platform that exceeds the capabilities of conventional production control systems, customers can take full advantage of the new features like Network-IO providing decoupling of hardware and software and the new Automation Design Suite.


Over the past decade, companies have been using unconventional drilling technology to extract gas and liquid from the readily available shale formations in North America. As the industry gains experience, the production rates continue to rise based on better use of technology to locate resources and to decrease the time from exploration to production.


yi-MAC stands for YOKOGAWA Innovative Main Automation Contractor:

  • Full control of scope and schedule across packages
  • Realization of customer expectation
  • Single point of responsibility
  • Providing fully integrated solutions

Network-IO can help reduce projects by decreasing the amount of time needed to implement the physical part of the process control system. A system with configurable I/O allows flexible "binding," in which the soft- ware configuration of the system can be loaded into the physical system at a late stage in the project.


The ability to deliver a full scope of project execution capabilities is becoming more important than ever for automation suppliers that wish to compete on a global scale. Process automation suppliers have always had some degree of project execution capabilities, but only recently have suppliers and end users begun to realize the true economic impact that precise and comprehensive execution capabilities can have on the success of an automation project and on plant lifecycle costs.


When a project is executed following the main automation contractor (MAC) method, front-end engineering and design (FEED) is conducted before actual delivery phases such as design, implementation, inspection, and shipment, to identify risks in advance and mitigate risks in delivery phases through the standardization of the basic functions and components.


Instrumentation devices and equipment serve for plants as the eyes, ears, nose, tongue, and skin, which are responsible for the five senses, and act as the central nervous system and brain do for human beings. The reliability and availability of such devices and equipment are the most important requirements of customers.
