Training over two half-days 16 and 17 September

The courses will be available by videoconference or face-to-face at TotalEnergies' premises at the CSTJF in Pau. The programme covers the use of ISO/TR 12489 for reliability modelling and the calculation of safety systems in the oil and gas industries, including low-carbon energy. The GRIF software suite developed by TotalEnergies will be used for the case studies.

 

ISO/TR 12489 is used in 35 countries

ISO/TR 12489 supplements part 6 of IEC 61508 (functional safety). It covers all systems with safety functions that are not necessarily subject to SIL requirements. The ISO technical report was developed by an ISO/TC67/WG4 project group and provides guidelines focusing on reliability modelling and calculation. Since its publication in November 2013, ISO/TR 12489 has already been adopted by 35 countries worldwide. This operationally focused course provides practical guidance on how to use ISO/TR 12489.

The GRIF software used to produce the case studies will be published at the second ESA RAMS conference in the Netherlands from 18 to 20 June. A unique RAMS forum for information exchange, technical discussions, definition of future directions and potential R&D areas, and networking opportunities.

 

Operating in safety

Risk management for the safe operation of assets in the world's energy industries is a fundamental challenge in the Oil & Gas industry, where the design of reliable safety systems is of paramount importance. Demonstrating the reliability of these safety systems is based on a qualitative demonstration combined with a quantitative probabilistic demonstration.
