Pipeline

• STARDOM and FAST/TOOLS integrated SCADA solution for Indian Oil Corporation's multiproduct oil pipeline.
• STARDOM facilitates the total visualization of data needed for safe and reliable pipeline operations.

India's flagship natural gas company GAIL Limited integrates all India's Gas Pipelines by a Yokogawa FAST/TOOLS SCADA system.

• FAST/TOOLS SCADA system centralized monitoring & control of India's gas pipelines.
• All operation data can be directly utilized for gas allocation and billing.

One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.

Floating-point format calculations have enabled physical quantities (in engineering units) to be used in calculations.

• Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
• During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
• Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.

Remote leak detection for pipe line was needed to meet new environmental statute. However cabling earthwork is strictly restricted to protect land environment.

Recently, several ARC Advisory Group analysts and management team members had a chance to sit down with the new Yokogawa President and COO, Mr. Takashi Nishijima, and several other top Yokogawa executives to discuss the company's burgeoning presence in the worldwide upstream and midstream oil & gas industry.

Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.

Tuning PID controllers can seem a mystery. Parameters that provide effective control over a process one day fail to do so the next. The stability and responsiveness of a process seem to be at complete odds with each other. And controller equations include subtle differences that can baffle even the most experienced practitioners. 

The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

Only 5% of data is transferred into meaningful information so, asks Frank Horden, Business Development Manager, Yokogawa Global SCADA Center, USA, how to ensure pipeline management data is translated into valuable knowledge?

Eduard van Loenen and Frank Horden, Yokogawa, describe utilising a modern SCADA system as a collaboration centre platform for bringing 'real-time' operations, maintenance and business information sources together in one integrated visualisation environment.

The line of functionality between supervisory control and data acquisition and distributed control system is blurring.  These two traditionally disparate technologies are now seen as competitors in similar application environments.

Supervisory control and data acquisition (SCADA) systems have been part of the process industries for many decades and cyber security measures need to grow as technology advances. SCADA systems are used in oil and gas pipeline and other remote control and monitoring applications, such as electrical transmission and distribution, and water/wastewater.

How much do you know about pressure transmitters? Are you accurately, quickly and reliably measuring pressure? Ultimately, the drive of any good pressure transmitter is to get an accurate, reliable pressure measurement to the data user quickly. This video gives you the answers to your basic questions about pressure and pressure transmitters.
