Tank Farm Construction & Oil Terminal EPC Contractor

What is a tank farm?

A tank farm — also called a petroleum terminal, oil depot or fuel storage terminal — is an integrated facility where multiple above-ground storage tanks are grouped together for the receipt, storage and dispatch of crude oil, petroleum products, chemicals or liquefied gases. Unlike a standalone storage tank, a tank farm is a complete operating system: it includes interconnecting piping manifolds, pumping stations, metering and loading/unloading gantries, fire-water networks with hydrants and foam systems, dyke walls for secondary containment, electrical distribution, instrumentation, tank gauging, SCADA/DCS automation and a control room.

Modern tank farm construction in India is governed by a matrix of standards — API 650 for tank design, OISD-244 for terminal layout and spacing, OISD-117 for fire protection, NFPA 11/15/30 for foam and fire-water, IS 803 for mild steel tanks, and PESO/CCOE for statutory licensing. The engineering, procurement, construction and commissioning (EPCC) of a tank farm therefore requires a contractor who can integrate all disciplines — civil, structural, mechanical (tankage + piping), fire safety, electrical, instrumentation and automation — under a single contract.

HAIL is that contractor. As a dedicated tank farm EPC contractor based in Vadodara, Gujarat, we bring the leadership experience of 2,000+ storage tanks and 300+ mechanical projects to every petroleum terminal construction assignment. Whether you are building a 4-tank diesel depot or a 27-tank crude oil terminal, HAIL delivers integrated EPCC with one schedule, one quality system and one point of accountability.

Types of tank farms we build

Tank farm design standards

Every discipline within a tank farm is governed by specific codes. As a tank farm EPC contractor, HAIL designs, procures and constructs to the full matrix of applicable Indian and international standards:

Complete EPCC scope for tank farm construction — discipline by discipline

What sets HAIL apart from a tank-only fabricator is the ability to deliver every discipline within a tank farm under one EPCC contract. Below is the detailed scope we execute on a typical petroleum terminal construction project:

Civil & structural works

The civil scope in tank farm construction is extensive — often 25 to 35% of the total project value. HAIL handles earthwork and site grading to achieve the required plot levels and oily water drainage gradients. We construct RCC ring-wall foundations for each storage tank, designed for the specific tank diameter, shell load and seismic zone. Dyke walls — brick masonry or RCC — are built around each tank group per OISD-244 dyke capacity requirements (100% of the largest tank or 50% of total group capacity, whichever is greater). We also construct pump house buildings, pipe rack foundations, control room buildings, fire-water pump house, gate house, weigh bridge foundation, internal roads, cable trenches and the oily-water drainage system with API oil-water separator.

Tankage — API 650 storage tanks

The heart of any tank farm is the storage tanks. HAIL fabricates and erects API 650 tanks for crude oil, petroleum products, chemicals and water service — cone roof, EFR, IFR and DDFR configurations up to 110 m diameter. Every tank follows our proven 12-step construction process: site survey, BOD, mechanical design, plate procurement to MTC, WPS/PQR qualification, ring-wall foundation, bottom plating, shell erection by jack-up method, roof construction, NDT (100% RT on shell seams, vacuum-box on bottom), hydrotest with settlement survey, and painting/lining/calibration. This tankage capability is the backbone of our tank farm construction service.

Tank farm piping

Tank farm piping connects every tank to the receipt, dispatch and recirculation systems. On a typical petroleum terminal, piping scope includes product headers (receipt and dispatch), tank inlet and outlet piping with block and bleed valves, pump suction and discharge piping, drain and slop piping, vapour recovery piping, vent piping, fire-water ring main, foam piping, instrument impulse lines and utility piping (service water, instrument air, nitrogen). HAIL fabricates, erects and tests all piping to ASME B31.3 / B31.4 with full radiography on critical welds. We also execute 3LPE-coated cross-country pipelines connecting tank farms to jetties, refineries or rail sidings — a critical element of oil terminal construction India projects.

Fire protection systems

Fire protection is non-negotiable in tank farm construction. HAIL designs and installs fire-water systems per OISD-117 and NFPA — fire-water ring main around the tank farm perimeter, hydrants at OISD-specified spacing, monitors for large-diameter tanks, deluge systems for LPG bullets, rim-seal foam pourers for EFR and DDFR tanks, foam chambers for cone-roof tanks, foam proportioning units (bladder tanks or balanced-pressure proportioners), diesel-driven and electric-driven fire pumps with jockey pump, fire-water storage tanks and foam concentrate storage. Our fire-protection scope meets the statutory requirements for PESO licensing of petroleum terminals.

Electrical & instrumentation

The E&I scope on an oil terminal construction India project includes HT/LT power distribution (incoming 11 kV / 33 kV, step-down transformers, LT distribution panels, MCC panels for pumps), cable laying in trenches and on cable trays, hazardous area classified equipment selection per IS 5572, earthing system design, lightning protection per OISD-141, illumination (flood lights, street lights, area lights), tank gauging systems (servo or radar type), flow meters (turbine, Coriolis, ultrasonic), pressure and temperature transmitters, level switches for high-high alarm and overflow prevention, gas detectors (catalytic and IR type for hydrocarbon vapour), and fire detection (linear heat detection for cable trenches, flame detectors for pump areas).

Automation, SCADA & control systems

Modern tank farms are automated facilities. HAIL integrates DCS/PLC-based control systems for batch transfer management, automatic tank gauging, leak detection, fire alarm and suppression logic, gas detection and emergency shutdown (ESD). We provide SCADA systems for remote monitoring — the control room operator can view tank levels, transfer flow rates, pump status, valve positions and fire alarm status on a single HMI. For multi-terminal operators like IOCL and BPCL, we configure communication links for integration with regional and head-office SCADA systems.

Dyke walls & secondary containment

Every tank within a tank farm construction project sits inside a bunded enclosure — the dyke — designed to contain the full volume of the largest tank in the event of a catastrophic failure. HAIL constructs dyke walls per OISD-244 requirements: minimum 1 m height, capacity equal to 100% of the single largest tank or 50% of the total tank group (whichever is greater), impervious lining on inner face, dyke drain valves (normally locked closed), access stairs and ramp for emergency vehicles. The dyke floor is graded toward a sump with leak-detection provisions and oily-water collection.

Tank farm construction process — from green field to first oil

A tank farm is a complex, multi-discipline EPCC assignment. HAIL follows a structured phase-gate approach refined over years of petroleum terminal construction across India:

1. Feasibility & FEED. Site assessment, soil investigation, environmental clearance support, plot plan development per OISD-244, tank sizing, P&ID development, fire-water demand calculation, preliminary cost estimate and project schedule.
2. Detailed engineering. Finalise all engineering deliverables — tank design calculations (API 650), foundation design, piping isometrics, structural drawings, electrical SLD, instrument hook-ups, cause-and-effect matrix, control narrative, MTO and procurement specifications.
3. Statutory approvals. Prepare and submit applications for PESO construction licence, PESO storage licence, factory plan approval, consent to establish (CTE) from State Pollution Control Board, and fire NOC.
4. Procurement & vendor management. Issue purchase orders for long-lead items — steel plates, piping, valves, pumps, fire-fighting packages, DCS/PLC hardware. Vendor drawing review, pre-inspection at manufacturer, and materials receipt inspection at site.
5. Site mobilisation & civil works. Establish site offices, labour camps and temporary facilities. Begin earthwork, grading, ring-wall foundations, dyke walls, roads, cable trenches and building construction.
6. Tankage erection. Fabricate and erect storage tanks in parallel with civil works — bottom plating, shell erection by jack-up method, roof construction, NDT, hydrotesting and painting.
7. Piping, fire protection & E&I. Install tank farm piping, fire-water ring main, foam systems, electrical systems, instrumentation and cable laying. This phase runs concurrently with later stages of tankage and civil.
8. Pre-commissioning. System-by-system checks — piping flushing and hydrotest, electrical continuity and insulation resistance, instrument calibration, loop checks, fire pump trial run, foam system functional test.
9. Commissioning & handover. Performance guarantee testing, PESO inspection, fire department inspection, operator training, punch-list closure and handover of complete documentation dossier including as-built drawings, test records, vendor manuals and spare parts list.

Tank farm construction for fuel depots and oil depots

Oil depot construction and fuel storage terminal projects are a core part of HAIL's portfolio. Indian oil marketing companies (IOCL, BPCL, HPCL) operate hundreds of inland depots for distribution of MS, HSD, SKO and ATF to retail outlets, bulk consumers and airports. These depots typically comprise 4 to 12 storage tanks (1,000 KL to 15,000 KL each), a truck loading facility (TLF), receipt pipeline or rail siding, fire-water system, metering skids, additive injection and a control room.

HAIL delivers turnkey oil depot construction — from site grading and ring-wall foundations through tankage, piping, fire protection, E&I and automation to commissioning. We have particular depth in the piping and metering scope that makes a fuel storage terminal operationally efficient: multi-product piping manifolds with motorised valves, positive displacement metering with batch controllers, temperature-corrected volume accounting, and SCADA integration for head-office monitoring.

For defence and strategic storage, we build hardened fuel depots with underground or mounded tankage, blast-resistant control rooms and redundant fire protection — all to military specifications alongside standard OISD and NFPA requirements.
