Oil Storage Terminals & Refineries Solutions

Integrated Engineering Excellence for Critical Assets

At EDOPEC, we recognize that the reliability and long-term performance of midstream and downstream assets depend on uncompromising engineering quality and operational discipline. With more than 22 years of specialized experience, we deliver integrated, end-to-end engineering solutions covering the full lifecycle of oil storage terminals, tank farms, and refinery process units—ranging from crude oil to refined petroleum products.

As a single-source EPC (Engineering, Procurement, Construction) contractor, we execute projects from conceptual design through commissioning and final handover. Our expertise in both greenfield and brownfield developments ensures that all assets are engineered, constructed, and maintained in full compliance with international standards and local regulations, including API 650 / 620, ASME, NFPA, and NACE. This disciplined approach guarantees maximum safety, operational efficiency, and extended asset lifespan.

Core Technical Competencies & Solutions

  Atmospheric & Pressurized Storage Tank Engineering

We provide complete engineering, fabrication, and erection services for hydrocarbon storage tanks across various operating conditions.

• Atmospheric Tanks (API 650)
  Design and engineering of Fixed Roof, External Floating Roof, and Internal Floating Roof tanks for crude oil and petroleum products.
  Our portfolio includes landmark projects such as the Istanbul Grand Airport (IGA) Fuel Terminal, featuring 30,000 m³ JET A-1 storage tanks.

 Tank Internals & Safety-Critical Equipment

The safety and efficiency of storage tanks rely on precision-engineered internal systems. We design and supply a complete range of critical components:

• Floating Suction Arms
  Robust 16”–24” Floating Suction Arms designed to extract product from the cleanest tank level.
  Manufactured using high-grade materials such as S355JR (ST52-3) with durable swivel joints, proven through successful deployments at Türkmenbaşı Oil Refinery and Nordic Storage (Sweden).

• Flame Arrestors & Pressure/Vacuum Vents (PVV)
  End-of-line Flame Arrestors and PVVs engineered for safe tank breathing operations.
  All units are tested in accordance with TS EN ISO 16852, ensuring reliable flame propagation prevention.
  Extensive references include OMV Petrol Ofisi, TÜPRAŞ, and IGA Fuel Terminal projects.

• Quality Assurance & Compliance
  Every supplied component is delivered with:

  • Inspection & Test Plans (ITP)

  • Full material traceability (e.g., AW-7075 Aluminum, AISI 304 Stainless Steel)

  • Dimensional inspection reports

  • Performance and certification documentation
    Ensuring strict adherence to project and regulatory requirements.

 Pipeline & Terminal Integration

We engineer the infrastructure that connects storage and processing units into a fully operational system.

• Pigging Systems
  Design and fabrication of Pig Launcher & Receiver Stations for pipeline diameters ranging from 8” to 32”, enabling efficient cleaning and inspection.
  Successfully delivered for major operators including OPET and Aytemiz.

• Loading & Unloading Systems
  Engineering of top and bottom loading arms, tanker access gangways, and transfer systems to ensure safe and efficient product handling.

 Asset Integrity & Corrosion Management

Long-term asset protection is achieved through advanced corrosion control strategies.

• Cathodic Protection Systems (NACE Compliant)
  Design and implementation of Impressed Current (ICCP) and Sacrificial Anode (SACP) systems for:

  • Tank bottoms

  • Buried pipelines

  • Marine and offshore steel structures

  Our experience includes large-scale projects for BOTAŞ, TÜPRAŞ, and STAR Refinery, covering both onshore and offshore environments.
