ProSafe-RS Safety Instrumented System

A World Class Safety Instrumented System (SIS) for Dependable Plant Safety

The ProSafe-RS is much more than just a shutdown system. It modernizes plant safety with dual redundant technology, a unique common architecture and high safety integrity level protection.

Complete DCS integration allows the ProSafe-RS to operate as an integrated control and safety system (ICSS) as well as a standalone safety system, providing SIS solutions for all your process safety applications.

Used in over 2,300 projects, from integrated process automation projects to standalone solutions, Yokogawa’s ProSafe-RS safety systems are built with competence, life cycle support and long-term sustainability.

Safely Tolerate Component Failure through Redundancy

maintain SIL3 operation during hardware failuresIn the real world, human error and electronics degradation create tangible risks for plants and industrial facilities. A safety system provides the best possible protection against these inevitabilities -- but not all safety systems are created equal.

Yokogawa’s patented Versatile Modular Redundancy (VMR) maintains SIL3 operation, even with multiple hardware failures across the system.

Reduce Complexity with Common Architecture

one architecture for DCS and SISThe ProSafe-RS is the world’s first fully integrated control and safety system, utilizing over 40 years of Yokogawa CENTUM technology.

One architecture between SIS and DCS allows for easier engineering and maintenance, and security functions can be configured across the entire system. With one window to manage SIS and DCS simultaneously, you can simplify the task of handling data and eliminate the need to monitor two separate systems, saving time and improving efficiency.

 

 

Operate Safely for Decades with Minimal Interruptions

safe operations without shutdownUnplanned shutdowns, spurious trips, sub-optimal testing and upgrades can cost plants millions of dollars of lost production every year.

Yokogawa’s safety solutions minimize interruptions with:

  • Highly reliable protection at all SIL levels
  • Real time dashboard, quantifying current and future risks
  • Virtual scenario testing to assess the impact of future bypasses and overrides
  • Online modification, which allows plants to continue to run during upgrade
  • Automated compliance reporting to optimize testing frequency
  • Cradle to grave service and lifecycle assurance

Overview:

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.

Overview:

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Overview:

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

Overview:

Network and system security is now a necessity in process automation industry. YOKOGAWA provides a service lifecycle solution for cyber security to ensure that the security measures and deployments are continuously enhanced, monitored and inspected.

This white paper explains the details of the security design, implementation, operation and validation solutions from the technical perspective.

LNG Industry, Summer 2012

Martin te Lintelo, Yokogawa, The Netherlands, discusses the need for better automation, measurement and control instruments to cope with the rising popularity of LNG.

Overview:

There is growing recognition of the importance of preventing serious accidents in the process control field in view of the potential scale of impact on society. The IEC 61508 and IEC 61511 international standards call for the reduction of risk using safety instrumented systems (SIS) as well as the configuration of multiple protective layers in a process control system in order to prevent major accidents.

Yokogawa Technical Report
Overview:

There are already safety systems on the market that have achieved safety integrity level SIL3 of the functional safety standard, IEC61508. However, most of them have achieved SIL3 by conversion of modules into dual-redundant or triplex form.

Yokogawa Technical Report
Overview:

The recent variety of industrial and railway accidents happening right before our very eyes make us painfully aware that "safety" must be put first and foremost. "Safety first" is a concept accepted by everyone and there is no room for disagreement. However, the author feels that, in some cases, the concrete objectives of "safety first" are not actually clear, and the grasp of the hazards is insufficient.

Overview:

In recent years it has become increasingly common for plants to be provided not only with the control layer of a production control system (DCS, etc.), but also with the protection layer of a safety instrumented system (SIS) to reduce the risk of industrial accidents. The safety instrumented system is indispensable for avoiding risks to a plant failure.

Yokogawa Technical Report
Overview:

Yokogawa proposed the VigilantPlant concept as an ideal plant that achieves fully optimized operation where all the necessary information is given to all the operators involved in the plant operation. In VigilantPlant, operators are able to quickly respond to changes in the external environment while the production activities run without any interruption.

Overview:

In Japanese industries which grew rapidly until the early 1990's, solid production techniques for creating high-quality products supported the development of manufacturing industries. However, the economic environment has been changing rapidly and tough global competition has become unavoidable. Particularly, the manufacturing industry must adapt not only to changes in economic environments but also to changes in social conditions such as emphasis on health, safety, and environment (so called HSE).

Overview:

Upgrading and renewal of plant facilities, including production control systems and safety instrumented systems, are essential for maintaining safe and efficient plant operation. Even though these activities are categorized as R&R, they require investment and customers are often required to evaluate the profitability for obtaining approval.

Yokogawa Technical Report
Overview:

Environment and safety are major topics on a global scale in recent times. As symbolized by the effectuation of the Kyoto Protocol, an interest in preserving the environment is growing worldwide, and there is also a tendency to criticize more severely, occurrences of industrial accidents that are accompanied by environmental contamination or which may cause damage, etc., to residents in the surrounding areas.

Overview:

Conventional safety instrumented system (SIS) is typically installed separated from a distributed control system (DCS) to eliminate interference from the DCS and assure safety. However, users increasingly wish to integrate SIS with DCS while maintaining the safety of safety controllers.

Overview:

Yokogawa's ProSafe-RS safety instrumented system is used for many applications as a system conforming to the safety integrity level (SIL) 3 defined in the IEC61508 international functional safety standard. To deal with temperature inputs, systems were conventionally configured using signal conditioners.

Overview:

The CENTUM CS 3000, a reliable distributed production control system, has been introduced worldwide with the objective of operating plants efficiently 24 hours a day, every day. The CS 3000 handles abnormal conditions in a plant appropriately and minimizes the chance of them developing into faults.

Overview:

Due to emerging competitors from the rapidly growing countries such as India and China and the global economic downturn triggered by the Lehman shock, many companies in the process industries are struggling to survive the severe global competition.
