Mapping and Surveying of Existing Pipelines for NNPC Retail

Project Overview

JOCALSH INTERNATIONAL was engaged by NNPC Retail Limited to execute a detailed mapping and surveying project of existing pipeline infrastructure across Lagos and Port Harcourt. The goal was to provide accurate, up-to-date geospatial data and pipeline routing information for integration into the client’s asset management system and for regulatory compliance.

The project involved the use of modern surveying technologies including Differential GPS, Geographic Information Systems (GIS), and ground verification methods. Our team ensured minimal disruption to operations while capturing precise positional data, alignment details, and environmental conditions along the pipeline corridors.
