End-to-end pipeline engineering from FEED and detailed design through to construction, hydro-testing and commissioning across Nigeria.

Pipeline Design and Construction

Service Overview

Infrastructure That Moves Nigeria Forward

Divcon Engineering delivers complete pipeline engineering and construction services for Nigeria's oil & gas sector. From small-bore facility piping to large-diameter cross-country transmission pipelines — our pipeline team has the expertise, equipment and track record to deliver reliably.

Our pipeline projects encompass the full project lifecycle: route survey and selection, environmental and social impact assessment, FEED, detailed engineering design, material procurement, construction, non-destructive testing, hydrostatic testing and commissioning.

We have successfully constructed pipelines for crude oil, natural gas, refined products and utility services across multiple states in Nigeria — working safely in challenging environments with consistent quality and on-time delivery.

Pipeline Scope

Our Pipeline Engineering Scope

01
Route Engineering
Detailed route survey, right-of-way acquisition support, geotechnical investigation and environmental impact assessment for new pipeline corridors.
02
Pipeline Design
Full detailed engineering including pipeline design calculations, pipe stress analysis, cathodic protection design and material specifications to ASME, API and DIN standards.
03
Construction
Mechanised and manual pipeline construction including clearing, grading, trenching, welding, coating repair, backfilling and surface reinstatement.
04
NDE & Testing
Non-destructive examination of all girth welds — radiography, ultrasonic testing — followed by hydrostatic pressure testing to verify pipeline integrity.
05
Valve Stations
Design and construction of block valve stations, scraper stations, pressure regulation facilities and associated civil, mechanical and instrumentation works.
06
Integrity Management
Pipeline integrity management programmes including intelligent pigging, cathodic protection monitoring, corrosion assessment and risk management.
