Examensarbetet genomfördes på AstraZeneca, Snäckviken hos fabriken API. Dess ångsystem har länge drabbats av oavsiktliga avbrott och detta har inte åtgärdats trots förebyggande insatser, vilket i sin tur har resulterat i produktionsbortfall. Syftet med denna studie är därmed att ta fram en långsiktig underhållsplan på komponentnivå som ska minska samtliga avbrott i ångsystemet. För att genomföra detta var det nödvändigt med litteraturstudier, avbrottanalys, nulägesanalys, besök på Snäckviken samt intervjuer. Studiens teoriavsnitt omfattades bland annat av väsentliga begrepp såsom underhåll, tidsbaserat- och tillståndsbaserat underhåll. Dessa termer bidrog till förståelsen av arbetet och framtagningen av resultatet och i sin tur även diskussionen. Det slutliga resultatet påvisade faktumet att det fanns tre komponenter som orsakade flest avbrott i systemet, och för en av dessa skapades det en underhållsplan. Planen omfattas av en underhållsbeskrivning, reservdelar/utbyteskomponenter, tidsutförande samt underhållsreperationer som inkluderar rekommenderad utförarkompetens. / The project was carried out at AstraZeneca, Snäckviken at the API factory. Its steam system has long been affected by unintentional interruptions and this has not been remedied despite preventive measures, which in turn has resulted in production losses. The purpose of this study is therefore to develop a long-term maintenance plan at component level that will reduce all interruptions in the steam system. To implement this, it was necessary with literature studies, current situation analysis, interruption analysis, visits to Snäckviken and interviews. The theoretical section of the study included, among other things, essential concepts such as maintenance, time-based- and condition-based maintenance. These terms contributed to the understanding of the study and the result, and in turn also the discussion. The result demonstrated the fact that there were three components that caused the most interruptions in the steam system, and for one of these a maintenance plan was created. The plan is covered by a maintenance description, spare parts / replacement

The management of equipment based on Reliability-Centered Maintenance (RCM) has been widely applied with great success in several industries such as military, commodity production, civil airliners, nuclear power plant and the petroleum industry since the reprint of RCM-II written by John Moubray in 1997.The application of RCM not only increases the reliability of the equipment and the assets of a company but also promotes the overall equipment effectiveness (OEE), which includes the excellent ok yield to order and the better productivity of the equipment. As a methodology, RCM differs from the traditional equipment maintenance in the aspect of emphasis of maintaining the ¡§function¡¨ of the equipment instead of the equipment itself. Therefore, the need of equipment maintenance results from the speed and the severity of function loss, which determines the strategy and interval of equipment maintenance. This is the major difference between RCM and time based maintenance (TBM). This article discusses the critical success factors that drive the application of RCM in steel plant. The result reveals that the application of RCM could promote the reliability of equipment, cut the cost of maintenance and increase compatibility of the steel plant. In order to facilitates the implementation of RCM in the steel mill, the basic skills of the management includes the construction of vision¡Bconsensus¡Bthe set up of regulation and the cultivation of innovating culture. so as to build an effective managing teamwork features in strong execution. As for the equipment management both the standardization and the strict deviation of equipment function(6£m) are vital to sustain the excellent equipment reliability. The Integration of Maintenance Management System(IMMS) consists of three components, CMMS(Computerized Maintenance Management System) and RTMS(Real Time Monitoring System) link by RCM. RCM acts as a bridge for the information flow of maintenance management in the IMMS and promotes the effectiveness of maintenance management.
