Availability increase: A model in maintenance optimization for spare parts at Hydro Karmøy

Abstract

With increasingly focus on efficiency, reliability and safety, the industry faces new challenges in areas where conservative thinking and outdated methods are current. This report analyses, debates and compares established routines with new thinking and research in an effort to create a model for optimized spare part management. The report is centered around keywords like:  Reliability Centered Maintenance  Failure Mode Effects and Criticality Analysis  Decision Logic  Preventative and Corrective maintenance The methods that are used is literature study, experiences from skilled personnel and a continuous contact with personnel at Hydro Karmøy. In the report there are used a case from the PILOT project at Hydro Karmøy, specifically transport of Oxide, with focus on critical components on the tankers. This to demonstrate the effects a correctly analyzed spare part management can have on efficacy and reliability when using the correct tools. As a step towards a more streamlined spare part management system, there have been developed a customized computer program that will perform many of the more demanding calculations and decisions. This program is fully interactive and customizable to fit the actual requests. Because of the reports limitation in terms of time and available information, the group have not had the opportunity to test the program. It is therefore recommended that it will be performed a test of the program, on basis of the theory the group has presented in the report. Trough solid research, calculations and analysis the group also provides recommendations to further areas of work to ensure that Hydro Karmøy´s maintenance program will be an industry standard, both internal and hopefully externally as well.
