Case Study: Effective Utilization on Customer Assets Through Long-Term Partnership (Bahrain)

Contribute to efficient and stable operation of plant by providing maintenance services of control system for more than 20 years
Reduce total cost of ownership (TCO) through life cycle with effective use of large-scale plant facilities
Preventing pollution by plant operation considering the environment and providing high quality products to society

The Bahrain Petroleum Company (M/s BAPCO) is the first refinery established in the Arabian Gulf. Since its inception, BAPCO has held a sustainable goal towards health, safety and environmental commitment. BAPCO had the 1st Distributed Control System of Yokogawa supplied in 1994 and over the last 24 years, all the Process Control Systems operating in BAPCO are maintained by Yokogawa. Yokogawa is recognized as a value-added partner in BAPCO’s quest for excellence towards environmental responsibilities. Yokogawa maintained BAPCO's Process Control System from 1997 to 2011 under the Annual Maintenance Contract and from 2012 onwards it has done so under Yokogawa's flagship concept of maintenance known as the Life Cycle Agreement (LCA), which will support BAPCO until 2022. As partners, BAPCO and Yokogawa have been successful in managing the large Process Control System installation with due diligence and the Life Cycle Agreement, which ensures that their equipment & instrument assets are always available, reliable, healthy and up-to-date and helps to reduce TCO (Total Cost of Ownership). With the continuous engagement between Yokogawa and BAPCO through the Life Cycle Agreement, maintaining the Process Control System and resolving any issues related to the system have been immensely helpful in enhancing the skillset of incumbents. The proactive approach towards the joint goal of environmental responsibility has ensured that Yokogawa is accepted more as a service solution partner rather than a mere service provider.

We believe that not only the recycling of resources but also diverse efforts to improve efficiency of the entire lifecycle contribute to a circular economy. Yokogawa with its systematic life cycle plan, obsolescence management and continuous engagement with BAPCO has safeguarded the Process Control System over the years and provided the path forward for upgrade and migration of the systems. BAPCO and Yokogawa aim for a sustainable future as common responsibilities to the industry and society.

- Message from Employee -

Yokogawa introduced the concept of a lifecycle agreement to BAPCO, listening to the pain points of the BAPCO maintenance team. Yokogawa Middle East & Africa identified concerns related to training, variable replacement costs, and performance evaluations/analyses of field instruments, providing a comprehensive proposal to BAPCO, which BAPCO management signed for multiple years. Yokogawa performed numerous modification projects and upgrades, resulting in up-to-date automation assets, improved systems efficiency, and increased stability of operations. During the delivery of lifecycle services, BAPCO contracted an additional eight Yokogawa process control systems and one safety system. BAPCO also asked Yokogawa to include these systems in the renewed contracts, as well as add mandatory lifecycle parts replacements in the lifecycle agreement renewal.

Case Study: Evolving Durability and Multi-Generational Design and Promoting Effective Use of Customer Property (CENTUM VP)

CENTUM VP, a distributed control system which provides customers with an optimized operation and engineering environment, has been developing its reliability and robustness through introducing the latest state-of-the-art technologies. The CENTUM series have been offering a smooth upgrade path from an existing CENTUM system into the latest one. It provides customers with the benefits of using the existing system yet allows them to adopt the latest technologies.

Supporting to stable operation of instrumentation systems

By updating obsolete components to maintain system functionality, transition can be achieved seamlessly.

RIO (Remote I/O) system upgrade

Realize short turn-around, reliable update to the latest system by fully utilizing existing facility assets. New devices for the RIO system upgrade are compatible with existing RIO in both function and physical form. Existing cabinets and terminal blocks can be re-used as they are; it is not necessary to change the wiring between the I/O device and the sensor or valve.
