Marine pollution is an escalating issue, particularly in shipping operations, where factors suchas oil spills, ballast water discharge, and plastic waste pose serious threats to marine ecosystems and global trade. This study seeks to assess the impact of marine pollutiononboth shipping operations and the marine environment, offering insights into its root causes, consequences, and potential solutions. This thesis describes the nature of marine pollution, its key sources and their effects whichbrings to light the escalating pollution problem and its consequences on marine biodiversity, fisheries, the economic viability of coastal communities and shipping operations. It highlightsthe regulatory measures such as Marine Pollution (MARPOL) and the Ballast WaterManagement Convention. The research methodology employs a descriptive survey design that gathers data frommarineengineers, ship operators, port officials and environmental officers. These findings areusedto propose solutions such as stricter enforcement of environmental regulations, adoptionofsustainable fuels and enhanced waste management strategies. This research emphasizes the dire need for industry-wide cooperation to diminish pollution, balance economic interests with environmental sustainability, and ensure the long-termresilience of both shipping operations and marine environment.

The pipelines that transport petroleum products across Nigeria are vital for the country’s economy and energy security. However, they are also exposed to various hazards and risks, suchas theft, sabotage, corrosion, impact damage, fire, explosion, and environmental pollution. Theserisks can cause significant losses of life, property, and revenue, as well as damage the reputationand credibility of the pipeline operators. Therefore, it is essential to conduct a hazard andoperability (HAZOP) study and a risk assessment of the pipelines to identify the potential causesand consequences of failure, and to propose appropriate mitigation measures. A Hazard and Operability (HAZOP) analysis of pipelines is a systematic and structured processused to identify potential hazards, operability issues, and risks associated with the design, operation, and maintenance of pipeline systems. This report presents the methodology and results of a HAZOP study and a risk assessment of thepipelines across Nigeria. The report also reviews the existing literature on the topic and
compares the findings with the data collected around the pipelines observed in around EdoState. The report also went ahead to calculate the third party damage index for some selected pipelinesand examines the pipeline right of way conditions in such locations. The report aims to provide useful information and recommendations for the pipeline, regulators, stakeholders, and researchers who are involved or interested in the safety and reliability of thepipelines across the State.
