Reliability Centered Maintenance : Different Implementation ApproachesAl Haiany, Haidar January 2016 (has links)
Mining equipment are becoming very sophisticated and complex. At the same time, mining companies modernise its operation by increased mechanisation and automation (Dhillon, 2008). That requires well-developed and planned maintenance strategy. A proper maintenance strategy and appropriate maintenance actions, are essential to keep equipment safe & reliable, decrease the overall costs, and it helps to eliminate workplace hazards. Maintenance strategies and maintenance actions, in turn, are changed and developed more than any technology (Moubray, 1997). Changing and developing of the maintenance can be due to many factors, perhaps due to the complexity of the systems or due to the development of the technology. One of the best research (developed technology) that has been done in this area is the research by Nowlan and Heap about Reliability Centered Maintenance (RCM) in 1978. RCM is defined as, “a zero-based, structured process used to identify the failure management strategies required to ensure an asset meets its mission requirements in its operational environment in the safest and cost – effective manner” (Regan, 2012). The RCM is one of the best powerful asset management strategies. RCM can be applied to any asset, nuclear power plant, aeroplane, or truck ship. According to (Nowlan & Heap, 1978), the main goal of implementation an RCM process is to provide the stated function of the facility with required reliability and availability at the lowest cost. In this master thesis, an RCM analysis process has been described in details. Moreover, two types of implementation approaches of an RCM analysis process have also been described. The intention of describing these two approaches is to see what the differences between them are and which one can be recommended for using in mining. The first approach is according to (Hinchcliffe & Smith, 2004) and the second approach is according to (Regan, 2012). Moreover, in this master thesis, there are also two case studies that have been analysed. The intention of analysing these two case-studies is to see how the RCM has been implemented. As a result of the research carried out in this master thesis, some basic streamline RCM analysis process has been recommended for using in mining. This recommended RCM analysis process could be applicable to be used in every industry section. The result of this work can be summarised that RCM is an applicable tool which can be used in mining for selecting the right maintenance approach for different equipment, systems or subsystem. RCM analysis process is discussed from different perspective. In the discussion, the misconceptions about the implementation of an RCM analysis process have been discussed. Altogether, Reliability Centered Maintenance is one of the most powerful asset management strategies that can be used in every industry section. If the RCM is applied by right people and by the right way, the result can be profitable for the mining companies.

Initiation of RCM on C20 trains at TBT Stockholm ABFarooq, Muhammad Omar, Vallabh, Samarth January 2010 (has links)
This thesis is an effort to implement Reliability Centered Maintenance “RCM” for C20trains at Tunnelbanan Teknik Stockholm AB. In depth study is performed along withmaintenance team of TBT at center of excellence, a facility for maintenance workshop. RCM is a philosophy or framework to ensure efficient working of assets according todefined and required operating context. In general, the successful implementation ofRCM can achieve improvements through lesser maintenance, operating techniquechanges, and generating inclusive maintenance plan. RCM is also one of the best toolsavailable to identify and prevent equipment failures. Therefore TBT has decided tointroduce RCM to ensure effective services with great confidence and precision. The selection of critical system of C20 train was obligatory to initiate implementation ofRCM, and the door system was considered a very complicated system with maximumfailures that results in traffic disturbances and stoppages. Through literature study,depots & workshop visits, brainstorming engineers & train drivers etc, the requiredtasks to be performed were lay down. A template that illustrates details such as FMECA,risk analysis, current maintenance strategy and the recommended actions wasprepared and new maintenance regime along with the changes in work instructionswere proposed. The cost effectiveness as well as safety assessment was carried out.Moreover, the efficacy of RCM analysis is directly proportional to quality and accuracyof available failure data, and the proposed time scale for thesis was underestimated andthe reason behind was the convolution of CMMS as well as poor quality of failure data. The study results are officially approved by all stakeholders, i.e. SL, MTR Stockholm,MTR HK and TBT. This work can guide the officials to take imperative decisions foroptimization of maintenance practices, also the study for C20 door system can be theroadmap for comprehensive implementation of RCM at TBT Stockholm AB.
