This report provides reliability data estimates for components of control and safety systems. Data dossiers for input devices (sensors, detectors, etc.), control logic (electronics) and final elements (valves, etc.) are presented, including some data for subsea equipment. Efforts have been made to document the presented data thoroughly, both in terms of applied data sources and underlying assumptions. The data are given on a format suitable for performing reliability analyses in line with the requirements in the IEC 61508 and IEC 61511 standards.

As compared to the former 2006 edition, the following main changes are included:

• A general review and update of the failure rates, coverage values, β-values and other relevant parameters;
• Some new equipment groups have been added;
• Data for control logic units have been updated and refined.
