Main Automation Contractor (MAC)

The ability to deliver the full scope of project execution in industrial automation projects is more important than ever. 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.

Increasingly, companies depend on Yokogawa to take on the role of main automation contractor, owning responsibility over the entire automation related aspects of the project.

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.

Yokogawa's main automation contractor (MAC) service delivers the full scope of project execution capabilities. Yokogawa assumes responsibility over the entire automation related aspects of the project, helping you meet budget, time, manpower, delivery, and risk management needs.

Project execution requirements are more important than ever—not only for automation end users, but also for engineering, procurement, and construction (EPC) contractors. Although projects need to be finished as quickly as possible, many EPC's are paring down their automation departments, and no longer have the time or resources to deal with multiple automation suppliers on a project. Therefore, an automation supplier with the right capabilities and experience can provide a single point of responsibility for project management, coordinating the work among multiple suppliers and subcontractors.

MAC AutomationYokogawa as a MAC assumes responsibility over entire automation related phases of the project. The Yokogawa MAC team constructs the most suitable project organization, works with directly with end users, EPC, and 3rd parties. With the MAC approach of dealing with Yokogawa directly, it isn't necessary for customers to make an effort to manage various automation suppliers.

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

Compared to a traditional approach, Yokogawa MAC enables drastic costs saving to 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 saving up to thirty percent 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.

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.

Descripción General:

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.

Descripción General:

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.
