Design, Procurement, and Installation of Cathodic Protection System – 12” x 14.5km Shagamu Phase 3 Gas Pipeline

Project Overview

JOCALSH INTERNATIONAL was contracted by TGNL/Sellyfak to execute the design, procurement, and installation of a full Cathodic Protection (CP) system for the 12” x 14.5km Phase 3 gas pipeline located in Shagamu. This pipeline forms a critical part of the region’s gas distribution network, and the CP system was designed to ensure long-term protection against external corrosion.

The project required precise engineering, sourcing of quality materials, and expert installation to ensure compliance with both local and international standards, including NACE SP0169. Our team successfully delivered the project under tight timelines and within specification.
