Online Training - Reliability, Availability and Maintainability Analysis

Dilihat 1512

OVERVIEW Reliability, Availability and Maintainability (RAM) is one of the most current maintenance program used in oil and gas industry at design (FEED) stage or in operation stage. The reliability data, in terms of MTTF, MTBF will be evaluated for each individual equipment and system. The reliability of the system is determined using a reliability block diagram by considering serial or parallel arrangement of the equipment that construct the system (e.g. gas process plant). Maintainability is defined, and assumptions are made according to data history of similar equipment/system or engineering judgment. Sensitivity analysis is also performed for various cases of MTTR including logistical support for parts and materials to evaluate which factors become the major contributors to the maintainability and availability. For RAM modeling, various foreseeable scenarios, including the effect of logistic time delay, can also be developed. The major cause for unreliability and unavailability related to down time will be discussed, and the necessary steps to avoid that condition will be recommended. In this training, the OREDA (2004), BS 5760 and ISO 14224 as primary RAM sources will be consulted. MATERI
