ABB recommends the use of Layer of Protection Analysis (LOPA) for SIL Determination. A calibrated risk graph can also be used for initial screening of simple low consequence scenarios where the required risk reduction is likely to be in the …

Calculation of a target SIL is based on individual SIFs (or generic SIFs). This is an important concept, as without having a clear definition of each SIF, and a target SIL for each of those SIFs, SIL verification becomes an impossible task.

To help you achieve functional safety lifecycle compliance in accordance with the relevant IEC safety standards, we provide Greenfield & Brownfield safety project execution, operation, and maintenance service support for installed Safety Instrumented Systems (SIS).

The following sections provide guidance on; − Responsibilities – the responsibilities of End User/ Operators and Engineering/Equipment suppliers in providing, compiling and demonstrating that the target SIL has been achieved − Identification of Hazards and SIL Determination – identifying the safety instrumented functions, and assigning ...

The ABB Ability™ System 800xA ® High Integrity safety system is TÜV certified for SIL3 and was designed with a flexible architecture, in a single configuration.

ABB works with our clients to create a workable and robust Achieved SIL report in line with the compliance requirements of the standards. By supporting end users and/or EPC’s develop the Achieved SIL documentation we provide the following benefits:

Our tools such as TRAC and TRAM are designed to help you execute and document SIL assessments and maintain your safety performance through alarm and trip management.

flexible and scalable SIL compliant design. The modular design of the hardware platform supports safety applications from small to large, single or redundant, with local or remote cabinet installations in configuration

This training is targeted to control and systems engineers, instrumentation and application engineers who are responsible for the selection of devices for Safety Instrumented Functions (SIFs) and/or verification of the achieved SIL of the SIFs.

The new ABB Ability™ Safety Plus for hoists, SIL 3 Hoist Monitor (SPHM) provides accurate safely limited speed, position control, acceleration and deceleration for a mine hoist, replacing a traditional system.
