Appropriate maintenance action can reduce maintenance expenses and improve maintenance benefits substantially. After introducing the definition and characteristics of risk-based maintenance (RBM), the authors describe the process of risk evaluation of equipment and put forward the maintenance strategies based on risk evaluation.

Merchant shipping has undergone a great transformation over the past three decades. The shipping market is highly competitive, which coupled with high crewing and fuel costs, leads to high operational costs. One of the paramount factor involved in vessel operation is the Maintenance cost and there is a dire need to keep this cost to a minimum. Fortunately th...

The study presented herein is aimed towards improvement of nuclear power plant safety by utilizing the probabilistic safety assessment methodology. A new time-dependent unavailability model of ageing safety equipment within the nuclear industry is proposed. Equipment ageing along with effects of corrective maintenance and preventive maintenance are modelled as an integral part of the new time-d...

Nowadays providers of maintenance and support related to industrial robotics are facing major challenges. Equipment producers around the world are urged to make significant efforts in order to provide high value added services in addition to their traditional product development and manufacturing business. A focal problem with maintenance as well as support of industrial robotics is the need to...

Accidents involving rotating equipment in chemical, petrochemical, petroleum, and gas plants can result in damage to other process equipment and catalysts along with lost production. Conversely, process upsets, process instrumentation failure, or failures of other process equipment can result in damage to rotating equipment. An effective rotating equipment loss prevention program will be an int...

In manufacturing enterprises, maintenance is a significant contributor to the total company’s cost. Condition Based Maintenance (CBM) relies on prognostic models and uses them to support maintenance decisions based on the current and predicted health state of equipment. Although decision support for CBM is not an extensively explored area, there exist methods which have been developed in order ...

For the aim of system health management, equipment and components are inspected periodically by manual or automatic systems to monitor their condition and to identify their level of degradation. A decision is then taken regarding replacement or maintenance, and this is based upon an analysis of the monitored data. In this view maintenance is carried out when a measurable machine condition shows...

In this paper, we consider field service in which service providers are responsible for maintaining equipment performance. To do so, preventive maintenance work is usually required in addition to repairs. Field service managers are often faced with the conflicting objectives of maintaining a high level of equipment availability and keeping a low service cost. A condition-based maintenance (CBM)...

With the continuous development of power grid, investment equipment assets is increasing sharply during 13th Five Year Plan Period. There a growing need for maintenance as ages and varies in different types from transmission to distribution equipment. Equipment base element healthy grid development. Therefore, it important raise efficiency quality status via operation maintenance. To improve ef...
