ABSTRACT This paper presents the results of a study conducted to determine whether unit-oriented construction drawings, which are being developed and used by shipbuilders using modern zone-oriented, or modular, construction techniques, will satisfactorily substitute for system-oriented detailed arrangement drawings in the Navy's life-cycle maintenance management process. The study concluded that modular construction drawings will provide the necessary data in a more usable format, and thus are the preferred approach for the Navy's use. However, the study also identified several additionally needed features that are not now being provided in unit-oriented drawings, but which must be included in order to meet the needs of planning and maintenance activities during the operational life of a ship. A number of other observations about drawing use and maintenance are provided.

The Relationship

The chapter explains in detail the maintenance management model (MMM) taken as a reference for the development of the book. The chapter is based on the eight phases of the MMM. The first three blocks determine the effectiveness of the management; the following blocks assure the same efficiency and continuous improvement in the following way: Blocks 4 and 5 include actions for the planning and scheduling of maintenance, including, of course, the capacity of planning of department of maintenance. Blocks 6 and 7 are dedicated to the evaluation and control of the maintenance and the cost of assets throughout their life cycle. This chapter of introduction briefly summarizes the process and the reference frame necessary for the implementation of the MMM. This chapter also presents the relationship between the eight phases of the maintenance management model proposed and the general requirements of the asset management standard ISO 55000 to show how the gradual implementation of the MMM largely covers the requirements of the standard ISO 55000.

Plant Life Cycle

For the past couple of decades there has been a change of emphasis in the world nuclear power from that of building new Nuclear Power Plants (NPP) to that of taking measures to optimize the life cycle of operational plants. National approaches in many countries showed an increase of interest in Plant Life Management (PLIM), both in terms of plant service life assurance and in optimizing the service or operational life of NPP. A strong convergence of views is emerging from different National approaches, particularly in the area of the economic aspects of NPP operation and in the evolution in the scope of NPP PLIM. The latter can directly affect the cost of electricity from NPP in an increasingly competitive environment. The safety considerations of a NPP are paramount and those requirements have to be met to obtain and to extend/renew the operating license. To achieve the goal of the long term safe, economic and reliable operation of the plant an Integrated Life Cycle Management Programme (ILCMP) is necessary. Some countries already have advanced PLIM Programmes while others still have none. The ILCMP objective is to identify all that factors and requirements for the overall plant life cycle. The optimization of these requirements would allow for the minimum period of the investment return and maximum of the revenue from the sell of the produced electricity. Recognizing the importance of this issue and in response to the requests of the Member States the IAEA Division of Nuclear Power implements the Sub-programme on “Engineering and Management Support for Competitive Nuclear Power”. Four projects within this sub-programme deal with different aspects of the NPP life cycle management with the aim to increase the capabilities of interested Member States in implementing and maintenance of the competitive and sustainable nuclear power. Although all four projects contain certain issues of PLIM there is one specific project on guidance on engineering and management practices for optimization of NPP service life including decommissioning. This particular project deals with different specific issues of NPP life management including aspects of ageing phenomena and their monitoring, issues of control and instrumentation, maintenance and operation issues, economic evaluation of NPP life cycle management including guidance on its earlier shut down and decommissioning. The paper describes in detail the full scope IAEA activities on different issues of NPP life management and some of its achievements in this field during the nearest past as well as plans for the future.

Lifecycle Management

Features of the lifecycle management process at an electrical network company are described, including a limited budget of repair programs, availability of legal costs, semantic heterogeneity of the subject area terminology, and a significant amount of accumulated historical data. An electrical network equipment life cycle period can be identified in which the total cost of equipment repairs will in the future exceed its capital replacement by new equipment with similar indicators. This gives grounds for drawing up a repair program and makes it possible to use not only technical, but also the economic and historical data of the production assets management system and the accounting information system. The aim of the study is to make the electrical network equipment life cycle management process more efficient by applying a decision making support system in managing the life cycle of equipment at electrical network companies with taking into account economic indicators. The existing electrical equipment life cycle management procedure based on technical indicators (the technical condition index, failure consequences, and failure probability) is analyzed. The equipment maintenance and repair schedule drawn up according to this procedure often includes equipment with overestimated indicators and entails excessive repair costs. The article presents an algorithm using which it is possible to determine the optimal replacement period for a group of homogeneous equipment at an electric network enterprise based on monitoring the change in the equipment state depending on repair costs. An ontological model of the electrical equipment life cycle management process is developed. A decision making support system in managing the life cycle of electrical network company equipment has been developed, the use of which makes it possible to reduce the costs in considering the electrical network equipment operation for the long-term future.
