The change in course recently taken by the Swedish Armed Forces results in an increased use of equipment, and thereby increased requirements of preventive maintenance. This paper aims to examine the current responsibilities for preventive maintenance in an army unit. The intended effect of this examination is to disclose possible flaws, and to help make routines for preventive maintenance more effective. The questions asked in this paper are; Who, in an army unit, is responsible for the routine maintenance? When is this responsibility valid? What demands does the technical service have on responsibilities for the routine maintenance? How are these demands met? How ought to be responsible for the routine maintenance? To answer these questions the author has chosen to use a descriptive method to show the current facts. A theorizing method is chosen to, from described facts, clarify the demands of the technical service on routine maintenance. A comparing method is chosen to compare responsibilities and the different responsibility-posts. This paper presents the following conclusions; Much of the current literature, concerning the subject, is in dire need of being synchronised and updated. Routines for how the supply-responsibility is to be most effectively distributed in the unit ought to be established. The user ought to be given more responsibility to choose what routine maintenance should be carried out.

The objective of this study is to propose an approach that assists facility managers in obtaining the needed information to establish a proactive roof maintenance plan. Two main methodologies are used in this research. The first approach, Historical Maintenance Data Analysis (HMDA), investigates and pinpoints the root cause of roof leaks by thoroughly collecting and analyzing roof maintenance records. HMDA hypothesizes that a mathematical model can be developed to reveal relationships between potential roof leak causes and leak incidences. The second approach, Roof Service Life Prediction (RSLP), investigates the applicability of the Factor Method in roof maintenance. The use of RSLP for leak predictions is based on the assumption that the first-time leak has a linear relationship with the estimated service life (ESL) of the roof. This research demonstrates that roof maintenance records can be used to predict and identify major factors that are likely causes of roof leaks in a mathematical causal model. Roof leaks are not totally random events and can be predicted. In this study, three parameters (Age, Workmanship, and Roof Repair) have a significant impact on the roof leaks probability within the first three years of a roof life. A unit change of workmanship and roofs age increases the odds of a roof leak. On the other hand, changes in roof repair decrease the odds of a roof leak. The Factor Method performed in the RSLP confirms the existence of a relationship between the ESL and the first-time leak. The correlations discovered are positive and significant to highly significant. The extents of correlation are found to be low to medium. The finding also illustrates a relatively simple and useful factor method technique that can be applied to the roof maintenance decision-making process. The estimated service life of a roof provides a reasonable estimation of a maintenance-free period. When ESL information is used in conjunction with knowledge obtained from HMDA, the new synthesis of knowledge will expand the facility maintenance professionals ability to develop and schedule a proactive roof maintenance plan.

Thesis (MTech (Business Administration))--Peninsula Technikon, 2001 / Maintenance of locomotives is the main function of Bellville Locomotive Traction Depot in the Western Cape. Therefore, it is important to have a sound maintenance plan in place, to prevent a negative impact on the availability and reliability of locomotive supply for hauling power to train services. The purpose of the research is to determine the causes of the increased frequency of maintenance through a case study relating to 35-class locomotives. The abnormal increased frequency of wheel change and inter-bogie control repairs on 35-class diesel locomotives is investigated. A research survey was adopted, which included questionnaires and personal interviews based on the literature search. The target group is L&N section, which includes below-deck maintenance, overhaul and change out, repairs to locomotive bogies, frames, wheels, snubbers, inter-bogie control and traction motors. Sixteen people are responsible for all below-deck repairs and service of 52 locomotives. The results of the research will expose the shortcomings of the maintenance plan and propose solutions. This will be achieved by testing the effectiveness of the existing maintenance plan at Spoornet through the identification of the causes for the abnormal increase in wheel changes and inter-bogie control repairs on 35-class diesel locomotives. The outcome from this case study research will be to quantify the benefits arising from the effective application of a maintenance plan.

M.Ing. / Maintaining and repairing building stock, repair and replacement of the infrastructure, has been a facet of the European building industry for more than 50 years. Deterioration of structures to a level that renders them unusable is a more recent occurrence in South Africa. World-wide changes in the proportion of construction expenditure on new construction and repair and refurbishing of existing structures has occurred only the last two decades. Today, nearly 50 % of such expenditure is on repair and renovation in comparison to proportions of 30 % of previous years. Projections indicate that this trend will continue at least to the next coming century. 1171 Such a substantial proportion of construction expenditure must be expected to influence the market for repair materials, specialized techniques and services. Therefore, a good understanding of the all range of modern concrete repair materials, associated techniques and services as well as latest developments in concrete rehabilitation technology is a prerequisite for designers and users of concrete structures. The following pages attempt to present the basic background of modern concrete repair approaches with regard to the intended use of building structures. They will also deal with the management of a repair project with realkalisation as a remediation strategy. The present condition of the Rand Afrikaans University main campus buildings will serve as a case study model.

Yes / Oil and Gas plants consist of a set of heat exchangers, which are used in recovering the waste heat from product streams to preheat the oil. The heat transfer coefficient of exchangers declines considerably during the operation period due to fouling. Fouling in heat exchangers is a complex phenomenon due to the acceleration of many layers of chemical substances across tubes of heat exchangers resulting from chemical reactions and surface roughness. In this paper, the fouling process was determined as a critical failure in the heat exchanger. Failure is an accelerated fouling layer across the heat exchanger tubes, which can be the reason for the clogging of tubes. Hence, a risk assessment was conducted using the Risk-Based Inspection (RBI) approach to estimate the probability of fouling in heat exchangers. The results showed that the RBI approach can be used successfully to predict the suitable time to shut down the plant and conduct the fouling cleaning process.
