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.

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.

Yokogawa Technical Report
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.

Overview:

Instrumentation devices and equipment serve for plants as the eyes, ears, nose, tongue, and skin, which are responsible for the five senses, and act as the central nervous system and brain do for human beings. The reliability and availability of such devices and equipment are the most important requirements of customers.

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.

Yokogawa Technical Report
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.

Webinars

    Overview:

    Safety systems are often regarded as a mandatory item to have installed in your process plant. Selecting a safety system is mainly focused on implementation in the most efficient and cost effective way. Decision makers do not always realize that a safety system needs to be implemented by expert staff and it needs to be maintained over decades of its life span. Furthermore, implementing your safety system the right way, will not only be cost-effective, but can also add to the efficiency of your process. During this webinar, Jan de Breet will discuss the extra benefits Yokogawa offers you with its ProSafe-RS Safety Instrumented System.
