Maintenance Engineering within Global Service.
Abstract. The aims of this thesis are the application of FMECA methodology
(Failure mode, effects and criticality analysis) and the consequent draft of a Maintenance Productive Planning, in the context of a Global Service contract. The FMECA is an analysis tecnique, that can be applied both in the design step and in the period of exercise of a machinery or a system, whose purpose is to highlight and analyse all the possible ways of breakdown, the relative consequences and order them for decreasing critical state. The Productive Maintenance Planning has as objective the formulation of planned manutentive actions to remove or limit the breakdown ways. This thesis has been developed in the Maintenance Global Services srl (Livorno) offices and in the Laviosa Chimica Mineraria S.p.A (Livorno) plant, and it is divided in four main steps. In the first one, mainly developed in the Maintenance Global Services srl offices, a failure analysis has been made and the critical machinery has been chosen; in the second step, the work has prevalently moved in the area used by the Maitenance Global Services srl inside the establishment of the Laviosa Chimica Mineraria S.p.A., and the functional break up of the machinery, previously chosen, has been made. In the third step the criticality analysis, through the application of the FMECA methodology, has been made; in the last step, taking advantage of the obtained results, the draft of a Productive Maintenance Planning was made.
