ProSafe-SLS is Yokogawa's solid-state, hard-wired safety instrumented system designed to meet the highest safety integrity requirements. The product line meets specific requirements for individual safety instrumented systems and offers all safety integrity levels (SIL 3-4) for the oil and gas, petrochemical, chemical, nuclear and conventional power industries.
ProSafe-SLS SIS is also fully integrated with Yokogawa's CENTUM VP process control system as well as the FAST/TOOLS SCADA software package.
The modular design of the ProSafe-SLS safety system 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 SIS solution when safety allows no compromise.
The ProSafe-SLS is a safety instrumented system that was designed for applications that 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, featuring Non-Safety-Critical functions such as interfacing with a Human Machine Interface, Process Control System, Sequence of Event Recording, or SCADA system.
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.

The modules that are used to build a system solution are grouped in various categories as summarized below:
Interconnection wiring actually programs the application into the system.
The Malampaya Deep Water Gas to Power project delivers gas from an off-shore gas field to three power plants near the city of Batangas (100 kilometers south of Manila) in the Philippines. The project consists of an off-shore production platform, a 504 km subsea pipeline, and an on-shore gas treatment plant.
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.
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.
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.
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.
Process Control and Safety Systems: Separate, Interfaced, or Integrated?
Jan DeBreet - 2015 ARC Industry Forum
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.
