Functional Safety – IEC 61508
Ensuring that a safety related system adequately performs the
required safety functions under all stated conditions within a defined
period of time.
Assessing the risk reduction required for a tolerable level of risk.
How likely is it that the function in question will perform its
assigned task when needed?
ID: ID: Autronica Fire and Security AS 13
It should be noted that a SIL number applies to a complete function
(SIF), i.e. the field sensor, the logic solver and the final element. It is
therefore incorrect to refer to any individual item or equipment having a
safety integrity level.
An individual component can be certified for use in a particular SIL
application, but such a certificate constitutes only part of the verification
effort, since the target SIL must be verified for the complete SIF.
How does SIL relate to individual components?

The Kristin gas and condensate field came on stream on 3rd
November 2005.
The field has been developed with 12 production wells in four
subsea templates, tied back to a semi-submersible production
platform.
Kristin is currently producing 10 million cubic metres of gas per
day. Daily production capacity from the field is 125,000 barrels
of condensate and just over 18 million cubic metres of rich gas.
The Kristin reservoir is located almost 5,000 metres below
ground.
Design and lifetime follow-up according to IEC 61508/61511.

The review consider dangerous faults (DU) from testing and operation (when needed).
This is in accordance with
IEC 61508/61511 definitions.
2 flame detectors was not connected to logic in SAS (2010).
1 point gas detector gives alarm, but not high alarm (2008).
1 manual call point problem with mechanical switch problem (2010).
1 heat detector in sauna physically damaged (2006).
2 detectors covered, 1 detector not connected to logic in SAS (2006). 2 detectors had wrong type mounted (2007).

The SINTEF report:
Self-Verifying Detectors
SINTEF Report no.: STF48 F93033 (Restricted)
The SINTEF research institute was asked to make a theoretical study of
the self-verification idea based on offshore statistics and technical
support from oil companies.
The research scope was to compare the different methods of testing
and to do life cycle cost calculations.
About SINTEF: The SINTEF Group is the largest independent research organisation
in Scandinavia. Every year, SINTEF supports the development of 2000 or so
Norwegian and overseas companies via our research and development activity.
