Engineering Procurement, Construction/Fabrication, and Installations

At OAJ & Company Investment Limited, we deliver end-to-end Engineering, Procurement, Construction/Fabrication, and Installation (EPCI) solutions for Nigeria’s oil, gas, and heavy industry sectors. By unifying every phase of infrastructure development under an integrated project management framework, we optimize project timelines, control costs, and ensure strict compliance with international engineering standards and Nigerian Content Development requirements.

From initial design concepts to final commissioning, OAJ provides turn-key solutions that support upstream, midstream, and coastal maritime operations.

Our Core EPCI Capabilities

1. Detailed Engineering & Technical Design

Our engineering team utilizes advanced technical design protocols to turn complex requirements into execution-ready structural, mechanical, and electrical blueprints.

• Scope: 3D structural modeling, process piping layouts, mechanical system schematics, and electrical instrumentation designs.

• Value: Front-End Engineering Design (FEED) and detailed engineering optimized for constructability and operational safety in harsh offshore and coastal environments.

2. Strategic Sourcing & Procurement

Leveraging robust local and international supply chain networks—and reinforced by our operational synergies across the West African energy market—we source high-grade materials and technical components efficiently.

• Scope: Sourcing specialized line pipes, heavy machinery, specialized valves, electrical systems, and structural steel.

• Value: Strict quality control, vendor verification, and seamless logistics clearing to eliminate downtime and supply chain bottlenecks.

3. High-Precision Construction & Fabrication

We execute heavy steel fabrication and specialized equipment assembly in certified yards and workshops using industry-best fabrication protocols.

• Scope: Cutting, high-integrity welding, assembly of structural steelwork, piping spools, process skids, and modular packages.

• Value: Rigorous non-destructive testing (NDT), structural integrity checks, and precise workshop craftsmanship before field deployment.

4. Site Transport, Installation & Commissioning

Our marine logistics asset base and field personnel ensure safe mobilization, heavy lifting, structural erection, and pre-commissioning testing at complex onshore and offshore locations.

• Scope: Heavy-lift transport, structural positioning, mechanical mounting, tie-ins, hydro-testing, and system pre-commissioning.

• Value: Flawless execution on-site, minimizing operational downtime while meeting rigorous HSE and NIMASA compliance benchmarks.
