Review of Key Factors Affecting Maintenance of Natural Gas Wayleaves to Enhance Efficiency of a Gas Distribution at GASCO

The maintenance of natural gas wayleaves is important for ensuring the safety, efficiency, and reliability of gas distribution systems, particularly as global energy demands continue to rise. This study explores the factors influencing the maintenance of natural gas wayleaves, focusing on operations at GASCO. Using a mixed-methods approach, the study collected data from 50 GASCO staff in Dar es Salaam, employing surveys, interviews, focus group discussions, and document reviews. Quantitative analysis was conducted using descriptive statistics and the Relative Importance Index (RII), while qualitative data were analysed using Content Analysis. Key findings revealed that budget constraints, environmental factors such as rainfall intensity, limited access to wayleaves, and human activities significantly impact maintenance operations. Technological adoption, manpower shortages, insufficient training, equipment failures, and regulatory compliance also influence maintenance practices, but to a lesser extent. The results show the need for improved funding, enhanced infrastructure access, weather-resilient strategies, community engagement, and targeted training initiatives to address these challenges effectively. This study provides actionable insights for stakeholders, emphasising the importance of prioritising key factors to enhance maintenance efficiency and safety. By adopting advanced maintenance frameworks and best practices, GASCO and similar organisations can strengthen the resilience of their natural gas distribution networks, aligning with sustainability and energy security goals
