Environmentally sustainable turnaround maintenance: A review of best practices

Turnaround maintenance (TAM) involves the planned shutdown of oil, gas, and petrochemical facilities for inspection, repair, overhaul, and restoration of asset integrity. While essential for safety, reliability, and operational continuity, TAM can generate environmental impacts such as waste, emissions, noise, energy use, water consumption, and material demand. This paper reviews literature on environmental sustainability in TAM and identifies practices that improve performance across planning, execution, monitoring, and close-out. A structured review was conducted using Scopus, Web of Science, and Google Scholar, covering English-language articles published between 2000 and 2024. From 65 initial articles, 25 peer-reviewed studies were selected based on relevance, methodological quality, and contribution. The findings show that sustainable TAM depends on early environmental planning, environmental management systems, waste minimization, emission control, resource efficiency, digital monitoring, stakeholder coordination, competent contractors, and continuous improvement. The review consolidates TAM-specific practices, control factors, indicators, policy implications, and future research directions.
