Preventing Unplanned Downtime

Yokogawa has the tools and experience to build control and instrumentation solutions that provide tangible benefits to oil and gas companies.

Challenges
Oil and gas wells are being drilled to greater depths and are distributed over ever wider areas, necessitating the adoption of increasingly complex technologies. Costs have risen proportionally. To help keep costs under control, it is essential to prevent equipment failures that can lead to unplanned downtime.

Our solutions
Unplanned downtime disrupts production plans and hurts the bottom line. The high availability of Yokogawa products prevents oil & gas fields from unplanned downtime, saving you money and increasing the safety of your process.
At the heart of the Yokogawa CENTUM series of distributed control system (DCS) systems is a unique “Pair and Spare” controller architecture, consisting of a redundant set of CPU modules, each of which is equipped with dual microprocessors. These two processors continuously compare their output and initiate a bump-less switchover if any mismatch is detected. By such means, CENTUM series systems attain an availability of 99.99999% (seven 9s). Other Yokogawa products such as the STARDOM RTU follow a similar design concept, utilizing the same error check and correct (ECC) memory found in high-end PCs and featuring twice the normal memory capacity to facilitate the long-term storage of gas volume data and other on-site information. This helps reduce downtime, improves system reliability, and increases maintenance efficiency by eliminating the need to travel to remote well locations.

Enabling Technologies

CENTUM VP
All of the hardware and software in the CENTUM series field control stations (FCSs) were developed by Yokogawa. With our knowledge of these systems inside and out, we have what it takes to help you maintain 99.99999% availability.

STARDOM
With features such as a 256 MHz 32 bit RISC processor, the FCN-RTU is an evolution of the field proven FCN/FCJ architecture, delivering both high performance and low power consumption. This low-cost model has four serial I/O ports and one Ethernet port, and thus meets the minimum requirements of SCADA applications.
