Abstract

Lean maintenance practices have gained prominence for enhancing operational efficiency, reducing waste, and improving overall performance in maintenance, repair, and overhaul (MRO) environments. Lean principles have shown success in various industries, but their applicability and effectiveness in the unique context of maritime MRO workshops is still relatively unexplored. This research employs a mixed-method research approach, which entails qualitative and quantitative data-gathering through interviews, structured questionnaires, and observations. The assessment of a South African maritime valves and pumps MRO workshop revealed a predominant reliance on reactive maintenance, with no implementation of lean maintenance practices. This approach could lead to significant inefficiencies, including the increased downtime of valves and pumps, higher maintenance costs, and operational disruptions. To address these problems, it is recommended that comprehensive lean maintenance training and standardised maintenance processes be implemented, enhanced data use be invested in, and a culture of continuous improvement be fostered.
