Clients are increasingly asking for maintenance in addition to design and construction work. Clients base that decision on the total cost of ownership. Faulty maintenance leads to breakdowns, risks and a lower remnant value. That is why Nacap focuses sharply on the optimum performance of maintenance. In situations where various specialists work together during the design and construction work, efficiency is maximised by combining that knowledge and expertise for maintenance. Maintenance is important to all of Nacap's products: from pipelines (see also management and pipeline management system), cabling, electrical and mechanical installation to civil construction.
These preventative maintenance measures involve checking, measuring, testing, cleaning, replacing and repairing the part in question. The maintenance measures are worked out in more detail for each (sub-)system in the work plan. The findings are registered and incorporated in the internal analysis and maintenance reports. Maintenance measures are proposed on the basis of these reports in combination with the failure behaviour and its implications. The objects are regularly inspected for physical and functional aspects. The preventative maintenance needed to keep them running properly is carried out straight away, which includes the preventative replacement of (minor) components. Nacap works in close partnership with its wholly-owned subsidiary RAS pipeline for the testing of pipelines.
Total cost of ownership Clients want to be informed of all the costs involved in a project: as well as the design and construction costs, a very important role is played by the operational costs and maintenance costs, the plant's life cycle and the remnant value. That is why clients are becoming more and more likely to ask for the total cost of ownership in tendering procedures. Producing the best total cost of ownership (TCO) therefore involves weighing up the construction, operational costs and maintenance costs against each other. Operational costs include aspects such as energy costs and the costs for the emission of harmful substances. The management and maintenance costs have to be incorporated in the overall project at a very early stage. Making the right design choices makes it possible to optimise the costs and the maintenance efforts. Determining the maintenance strategy: Prevention or response/repair The maintenance activities can be primarily directed either at preventing faults or at promptly responding/repairing. Maintenance aimed at preventing faults is called preventative maintenance, or condition-dependent maintenance. In cases where prevention is unnecessary, unsuccessful or too expensive, the solution is reactive, fault-dependent maintenance. The problem is responded to by the fault-clearing service once a fault occurs. To make the best possible choice between preventive or reactive maintenance, it is important to carefully consider both the known and the potential costs (based on risk and impact). The implications of a fault are clarified on the basis of various fault analyses. Fault types with a sudden fault mechanism can only be maintained on a fault-dependent basis. The response time (including effective communication and registration) is extremely important to fault-dependent maintenance and efficient settlement (e.g. the immediate identification of the risks, the right equipment, the ability to obtain parts quickly).
