ProSafe-SLS

Yokogawa is the world's most experienced safety and control firm. Our commitment to providing reliable, state of the art safety instrumented systems is rooted in a wealth of installations since 1962.

The solid-state, hard-wired ProSafe-SLS covers all requirements in process industries. The product line covers specific requirements for individual safety instrumented systems and offers all safety integrity levels (SIL 3-4) for the oil & gas, petrochemical, chemical, nuclear and conventional power industries.

ProSafe-SLS safety instrumented system is also fully integrated with Yokogawa's CENTUM VP process control system together with ProSafe-RS safety system as well as FAST/TOOLS SCADA software package.


Inherent fail-safe

The modular design allows for building all kinds of applications, ranging from small HIPS systems to large ESD and F&G systems, while maintaining the fastest possible response time to follow any process demand.

ProSafe-SLS provides the ultimate solution, when Safety allows no compromise.

Safety-by-design

The ProSafe-SLS is a Safety Instrumented System that was designed for applications, which require the highest Safety Integrity Levels (SIL 3 & 4).

It employs solid-state elements to process the functional logic. This technology is capable of executing all typical Safety tasks, as well as the related supplementary Non-Safety-Critical functions. This comprises interfacing with a Human Machine Interface, Process Control System, Sequence of Event Recording system, SCADA system, etc.

The sophisticated design and superior Safety performance have created the Safety reference standard for solid-state Safety Instrumented Systems.

A radical Safety achievement, is the elimination of software for an operating system and for self-diagnostics. Instead, a unique inherent self-test technology is employed, throughout all Safety-related parts of the ProSafe-SLS system.

System Structure

8-channel digital input module

The modules that are used to build a system solution are a grouped in various categories as summarized below:

  • Input modules
  • Logic & Timer modules
  • Output modules
  • Power & Clock modules
  • Auxiliary modules
  • Communication & Interface modules

Interconnection wiring actually programs the application into the system.

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.

Many published papers discuss the benefits of subsea HIPPS and many studies show the potential cost-benefit analysis of this technology in deepwater applications. An internet search for subsea HIPPS is informative; however, little appears that discusses the systems already delivered and operating successfully.

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:

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:

    Yokogawa South Africa was appointed to design, supply and commission the Integrated Control and Safety System (ICSS) as well as the overall Terminal Management System at Sunrise Energy’s liquid petroleum gas (LPG) Import Terminal, the largest on- and offshore open-access LPG import terminal facility in Africa. Yokogawa’s Terminal Management System, Terminal Logistic Suite VP (TLSVP), was designed and developed to meet the exacting operational demands and logistic needs in terminals. Yokogawa’s experienced engineering resources ensured the project was successfully delivered, enabling Sunrise Energy to provide accurate mass balances and efficient terminal operations to its customers.
