Assessment of corrosion protection practices on Nigerian National Petroleum Corporation pipe lines in Ondo State for security of life and properties.

Abstract

This study was designed to assess the corrosion protection practices on Nigerian National Petroleum Corporation (NNPC) pipelines in Ondo State for security of life and properties. A descriptive survey design was adopted for the study. Three research questions and twohypotheses guided the study. The respondents randomly sampled were 80 Pipeline MaintenanceTechnicians and 30 Engineers who have served for at least 6 months. Mean scores were used to answer research questions while independent t-test was used to test the hypotheses. The findings revealed among others that: NNPC complied with most of the policies concerning pipeline design standards, physical routine checks on pipes, computer monitoring system were adopted as maintenance strategies and that fusion-bonded epoxy (FBE) coating as one of the modern ways of corrosion protection techniques is being complied with. It was therefore recommended among others that preventive maintenance should be carried out on weekly basis to prevent breakdown of pipeline system and on occasions of rupture or spillage due to corrosion, breakdown (corrective) maintenance should always be emphasized, external corrosion should be tackled using fiberglass reinforced polymer (FRP) for the security of life and properties of people leaving around NNPC pipelines.
