An investigation of energy-based planned maintenance of offshore drilling mud pumps.
… fluid end has been identified as requiring more maintenance work due to component failure, compared to the power end. The most common maintenance strategies in use include breakdown maintenance, time-based maintenance and condition monitoring. Time-based maintenance, based on running hours, is …

Development of an Efficient Planned Maintenance Framework for Marine and Offshore Machinery Operating under Highly Uncertain Environment
… of marine machinery design, operation and maintenance. An important finding from the literature exposed that failure to marine machinery can cause both direct and indirect economic damage with a long-term financial consequence. Notably, many cases of machinery failures reported in databases …

Quantifying the impact of digitalization on manufacturing supply chain management (SCM) in a power generation company
… study examines the visualization effect on the unplanned machine downtime, planned maintenance, and machine utilization. The assumption of the decrease in unplanned machine downtime, increase in early-stage planned maintenance, and increase in machine utilization are tested using non-parametric …

Sustainable building maintenance within social housing
… the sustainability agenda with social housing maintenance decision making in order that the sustainability of existing social housing stock can be improved through planned maintenance (and refurbishment). The thesis presents the argument that the current single criterion, conditioned based …

Improvement of service level through lean tools in a plastics manufacturing company
… of two lean tools: the 5S methodology and planned maintenance. The implementation of this model showed significant improvements: the incidence of lost products was reduced to zero, machine availability was increased by 15%, and the service level was raised by 1.24%. This model demonstrated …

Enhancing machine availability in plastic SMEs through lean and TPM: evidence from a peruvian case study
… of Lean Manufacturing and Total Productive Maintenance (TPM) for improving equipment efficiency, yet the integration of these methodologies in SMEs remains limited. This research addressed these challenges by developing a production model integrating Lean Manufacturing tools, such as SMED …

Modelling and simulation for the joint optimisation of inspection maintenance and spare parts inventory in multi-line production settings
… to model the joint optimisation of preventive maintenance and spare parts inventory in multi-line settings. The multi-line machines are subject to failure, based on the delay-time concept, and a selection of policies are used for the replenishment of the machines’ critical component. Production …

A Conditional approach to the tribology of RNLI marine systems.
… often subjected to either under or over engine maintenance due to the unpredictable usage of lifeboats. This research has demonstrated the key lubricant properties which were affected by the lifeboat operations. Analysis of used lubricants was conducted such as Wear Debris Analysis (Analytical …

An investigation into the potential of advanced sensor technology to support the maintenance of pipeline distribution systems
… infrastructure. Traditionally, built-environment maintenance is a capital-cost-driven activity that relies either upon the subjective assessment of a built environment and infrastructure condition (i.e. a stock condition survey) to identify maintenance needs, or upon a reactive response to a …

A study of US nuclear power boiling water reactor, class IV, operating performance, 1992-1997
… The loss of generation capacity taken for planned maintenance outages and on line maintenance for minor equipment problems was not found to have a significant impact on aggregate BWR/4 performance. For plants not involve in lengthy shutdowns, the strongest impacts on cumulative capacity …
