Reliability engineering the evaluation of the probability that an item can perform a required function under stated conditions for a given period of time. SynergenOG typically performs this study based on international codes and standards (British Standard, BS 5760), where reliability of a system is represented in terms of a Reliability Block Diagram (RBD). RBD is a pictorial representation of the logical interdependencies (parallel or series paths) required for the system under analysis to function correctly.
In order to evaluate the RBD, SynergenOG invested in the latest version of DNV GL’s software, Maros, which is an advanced Reliability, Availability and Maintainability (RAM) analysis tool specifically developed for performance forecasting in the upstream oil and gas industry.
SynergenOG built their own RBD within the Maros software, which identifies the components within the system and their operating mode. Maros predicts the performance of a system using simulation techniques. An ‘Event-Driven’ algorithm is used to create life-cycle scenarios of the system under investigation accounting for its reliability, maintainability and operating policies. By studying performance results and how they respond to altering specific parameters in the design or its logistics, it is possible to optimise the system with respect to given constraints.
