Oil and Gas Tenders in India: How to Win Contracts from ONGC, IOCL, BPCL, HPCL, and GAIL

A single offshore drilling rig contract from ONGC can exceed Rs 10,000 crore. A refinery expansion EPC from Indian Oil can run to Rs 30,000 crore. A cross-country pipeline construction contract from GAIL routinely crosses Rs 5,000 crore. These are not government projects in the usual sense: they are industrial mega-contracts backed by the balance sheet of some of India's most profitable companies, operating to international engineering standards, and demanding vendor capabilities that most suppliers cannot match.

That is also why the companies that do break through into oil and gas procurement find it one of the most lucrative and stable business categories available. Recurring AMCs, rate contracts, and multi-year service agreements create revenue predictability that is hard to find in competitive commodity bidding. If you have the technical capability and the patience to navigate the vendor registration process, oil and gas is worth the investment.

The Scale of India's Oil and Gas Procurement

India is the world's third-largest energy consumer. The country has 23 operational refineries with combined capacity exceeding 250 million metric tonnes per annum (MMTPA), over 35,000 km of crude oil and product pipelines, a natural gas network exceeding 22,000 km, and a growing city gas distribution (CGD) network covering hundreds of districts.

All of this requires continuous procurement. Here is the scale across the major buyers:

The combined procurement across these companies exceeds Rs 2 lakh crore annually, and this does not include procurement by joint ventures, CGD companies (IGL, MGL, Adani Gas, GSPC), and petrochemical subsidiaries.

Understanding the Buyers by Segment

Upstream: ONGC and Oil India

ONGC is India's largest oil and gas exploration and production company. It operates both onshore (in Assam, Rajasthan, Gujarat, Andhra Pradesh) and offshore (Mumbai High, Eastern Offshore), with Mumbai High remaining the flagship field.

What ONGC procures in the upstream segment reflects the full range of E&P activities:

Drilling services and rigs: ONGC is India's largest buyer of drilling services, contracting onshore drilling rigs (typically trailer-mounted, 1000-2000 HP) and offshore rigs (jack-ups, semi-submersibles) through multi-year charter contracts. Individual offshore rig contracts can run Rs 5,000-15,000 crore over a 3-5 year period, making them among the highest-value single contracts in Indian public procurement.

Subsea and offshore equipment: Christmas trees (wet and dry), wellheads, manifolds, umbilicals, flexible risers, and ROVs (remotely operated vehicles) for offshore field operations. These are highly specialised items requiring API certification.

Well services: Cementing, stimulation (hydraulic fracturing, acidizing), coiled tubing, wireline logging, completion tools. These are typically contracted to specialist service companies like Halliburton, Schlumberger/SLB, Baker Hughes, and their Indian JV partners.

Seismic surveys: 2D and 3D seismic data acquisition (both onshore and offshore), data processing, and geophysical interpretation services. ONGC is one of the largest buyers of seismic services in Asia.

Marine vessels: Offshore supply vessels (OSVs), anchor handling tug supply vessels (AHTSVs), platform supply vessels (PSVs), and diving support vessels. The Mumbai High field alone requires a fleet of 50+ vessels continuously.

Production facility construction and modification: Wellhead platforms, process platforms, FPSOs (floating production, storage and offloading), onshore processing terminals, and gathering stations.

Oil India Limited focuses on northeastern India (Assam, Arunachal Pradesh) and Rajasthan, procuring similar upstream categories but at smaller scale. OIL's northeastern operations create opportunities for vendors comfortable with challenging logistics in hilly terrain, which limits competition compared to ONGC's mainstream procurement.

Midstream: GAIL

GAIL (Gas Authority of India Limited) manages India's natural gas transmission backbone: the HVJ (Hazira-Vijaipur-Jagdishpur) pipeline and a growing network of regional and sectional pipelines totalling over 22,000 km.

GAIL's major procurement categories include:

Pipeline construction EPC: GAIL regularly issues tenders for new cross-country natural gas pipeline sections. These EPC contracts cover survey and route alignment, right-of-way acquisition facilitation, pipe procurement, welding and laying, hydrotesting, cathodic protection, and SCADA integration. A single 300 km pipeline EPC contract can exceed Rs 3,000-5,000 crore.

Compressor stations: Gas compression equipment (centrifugal and reciprocating compressors), drivers (gas turbine, electric motor), cooling systems, and associated piping. Compression equipment is typically sourced from international manufacturers (GE, Siemens, Rolls-Royce, Atlas Copco) with local civil and mechanical EPC executed by Indian contractors.

LNG terminals: GAIL's Dabhol LNG terminal and planned new terminals require specialised cryogenic equipment, insulated piping, storage tanks, and regasification equipment.

Petrochemical plants: GAIL's petrochemical operations at Pata (UP) require specialised chemical plant equipment, catalysts, and maintenance services.

City Gas Distribution (CGD): GAIL distributes natural gas in several cities through its CGD networks, procuring steel mains, MDPE pipes, pressure regulators, and CNG dispensing equipment.

Downstream: IOCL, BPCL, and HPCL

The three major downstream PSUs share many procurement categories because they all operate refineries and nationwide retail networks.

Refinery EPC and expansion: The most valuable single-contract opportunity. IOCL's planned Nagapattinam greenfield refinery (9 MMTPA), BPCL's Bina and Kochi refinery expansions, and HPCL's ongoing Barmer (Rajasthan Refinery) project are all multi-thousand-crore opportunities. Major EPC contractors for Indian refinery projects include L&T Hydrocarbon, Toyo Engineering, Tecnip Energies, and the Indian arms of international EPC firms.

Catalysts and chemicals: FCC (fluidised catalytic cracking) catalysts, hydrotreating catalysts, reforming catalysts, and speciality additives are recurring procurement items for all downstream PSUs. Indian catalyst manufacturers (Hindustan Cuso, Cecon) compete with international suppliers (BASF, W.R. Grace, Albemarle).

Pipeline materials and construction: Carbon steel pipes (API 5L grades), ball valves, gate valves, butterfly valves, pig launchers and receivers, cathodic protection systems, and pipeline coating. IOCL's pipeline network expansion requires procurement of thousands of kilometres of pipe annually.

Tankage and storage: Floating roof tanks (FRT), fixed roof tanks (FxRT), LPG spheres, aviation fuel storage, and fire protection systems for tank farms.

Retail outlet equipment: Fuel dispensing equipment, submersible pumps, automation systems, canopy structures, and underground fibre-reinforced plastic (FRP) tanks for IOCL's 35,000+ petrol pumps, BPCL's 19,000+ outlets, and HPCL's 19,000+ outlets.

Information technology and automation: SCADA systems for pipeline management, distributed control systems (DCS) for refinery process control, historian systems, cybersecurity infrastructure, and retail automation (POS, FMS, inventory management).

Technical Standards: The Non-Negotiable Qualification Layer

Oil and gas procurement is the most standards-intensive sector in Indian public procurement. Before you can even think about price, you must demonstrate compliance with the applicable technical standards.

API Standards

The American Petroleum Institute (API) standards are the global foundation for oil and gas equipment quality:

• API 5L: Specification for line pipe (carbon steel pipeline pipe). If you supply pipeline pipe to ONGC or GAIL, your pipe must be API 5L certified.
• API 6A: Specification for wellhead and Christmas tree equipment. Mandatory for wellhead equipment suppliers to ONGC.
• API 6D: Specification for pipeline valves (gate valves, plug valves, ball valves, check valves). Required for most pipeline valve supply to downstream PSUs.
• API 610: Centrifugal pumps for petroleum, petrochemical, and natural gas industries. Required for refinery and pipeline pump supply.
• API 650: Welded tanks for oil storage. Required for storage tank construction for IOCL, BPCL, HPCL.
• API 682: Pumps and shaft sealing systems (mechanical seals). Required for rotating equipment in refinery applications.

API certification requires product testing at approved third-party laboratories and audit of your quality management system. The cost and time investment is significant but is non-negotiable for most upstream and downstream equipment categories.

ASME Standards

The American Society of Mechanical Engineers (ASME) standards are required for pressure vessels, heat exchangers, boilers, and piping:

• ASME Section VIII Division 1/2: Pressure vessel design and construction. All pressure vessels in refineries must comply.
• ASME B31.3: Process piping for chemical, petroleum refining, and related industries. All piping within refinery battery limits.
• ASME B31.4: Pipeline transportation systems for liquids and slurries. Product pipeline piping.

ASME-code fabricators require QA/QC programs, third-party inspection, and certified welders. If you are an equipment fabricator, ASME U-stamp (for pressure vessels) or R-stamp (for repairs) is the entry ticket to refinery equipment supply.

NACE/AMPP Standards

NACE International (now merged into AMPP - Association for Materials Protection and Performance) standards govern corrosion protection:

• NACE MR0175 / ISO 15156: Materials requirements for equipment in H2S-containing environments (sour service). Critical for upstream ONGC procurement.
• NACE SP0169: Control of external corrosion on underground metallic piping. Required for pipeline cathodic protection design.

OISD Standards

The Oil Industry Safety Directorate (OISD) under the Ministry of Petroleum and Natural Gas issues Indian safety standards for the oil and gas sector:

• OISD-118: Layouts for oil and gas installations (hazardous zone classification).
• OISD-117: Fire protection facilities for petroleum refineries.
• OISD-219: Safety requirements for petroleum dispensing pumps at retail outlets.

OISD compliance is mandatory for all equipment installed in Indian oil and gas facilities, regardless of whether the equipment also meets API or ASME standards. Some OISD standards are more stringent than their international equivalents for specific parameters.

Vendor Registration: How to Get on the Approved List

Each oil and gas PSU maintains its own vendor registration system. Without registration, you cannot bid on most supply contracts.

ONGC Vendor Registration

ONGC's vendor registration is managed through its e-procurement portal (eprocure.ongc.co.in) with materials management handled through the Integrated Materials Management system.

ONGC registration categories align with its major material groups: drilling equipment, production equipment, chemicals, pipes and fittings, electrical and instrumentation, civil materials, and services. The registration process requires:

• Company profile with manufacturing capability details
• Statutory registrations (GST, PAN, MSME if applicable)
• Quality certificates (ISO 9001, API, ASME as applicable to product category)
• Financial stability assessment (net worth, turnover requirements vary by category)
• Technical assessment (sometimes requiring plant visit by ONGC team)
• Type test reports or performance certifications for specific equipment

For new vendors without prior ONGC experience, the first step is typically a developmental vendor registration for smaller value orders, progressing to full approved vendor status after satisfactory performance on trial orders.

IOCL Vendor Registration

IOCL manages vendor registration through its dynamic vendor registration portal. Registration categories include mechanical equipment, electrical equipment, instrumentation, civil materials, chemicals, and services.

IOCL's registration process is similar in structure to ONGC's but with different category thresholds and slightly different documentation requirements. IOCL has been actively expanding its domestic vendor base under Make in India, and new Indian manufacturers in equipment categories previously dominated by imports receive faster consideration.

BPCL, HPCL, and GAIL

BPCL, HPCL, and GAIL each have their own registration portals, and registration is not portable between companies. If you want to supply to all downstream PSUs, you must register separately with each.

However, the documentation requirements overlap significantly. If you have API 6D certification for your ball valves and a successful track record with IOCL, the BPCL and HPCL registration process for the same product category will be substantially easier.

Types of Tenders by Value and Accessibility

Global Tenders (above Rs 100 crore or for proprietary items)

For contracts above Rs 100 crore, oil and gas PSUs typically issue global tenders open to both Indian and international bidders. Technical qualifications are stringent, and contracts often require performance bonds, parent company guarantees, and third-party inspection during execution.

Global tenders for drilling services, offshore equipment, speciality catalysts, and major compressor packages attract international competition from companies like Halliburton, SLB, Baker Hughes, Air Products, Howe Baker, and others.

Limited (Approved Vendor) Tenders

The majority of recurring supply contracts go through limited tenders restricted to approved vendors. Once you are on the approved vendor list, you receive tender notifications and can bid on these orders, which are typically more stable and predictable than open competitive tenders.

Open Domestic Tenders

For routine materials (common pipes, fasteners, paints, safety equipment, office supplies), oil and gas PSUs issue open domestic tenders through their portals. These are the most accessible entry points for new vendors. They have lower technical barriers than equipment supply tenders and allow you to establish a track record that supports future vendor registration applications.

Turnkey and EPC Contracts

Large EPC contracts for refinery units, pipeline sections, and processing plants are issued through competitive bidding among qualified EPC contractors. Eligibility requirements (financial turnover, similar project experience, technical staffing) screen out smaller players. Most large EPC contracts require a consortium or JV if no single company meets all criteria.

Finding Oil and Gas Tenders

Oil and gas tenders are scattered across multiple portals:

• ONGC: eprocure.ongc.co.in (its own portal) plus CPPP for some categories
• IOCL: iocletenders.co.in plus CPPP for high-value tenders
• BPCL: bpcletenders.co.in
• HPCL: hpcletenders.co.in and hpcl.co.in tender page
• GAIL: gail.co.in tender portal
• OIL: oil-india.com e-procurement portal
• MRPL: mrpl.co.in tender section
• CPCL: cpcl.co.in tender section

Without a system to aggregate these portals, monitoring even the six major PSU portals manually is a daily effort that risks missing opportunities.

HSE Compliance: The Often-Ignored Prerequisite

Oil and gas PSUs have significantly more stringent health, safety, and environment (HSE) requirements than other government buyers. Before a contractor starts work on any oil and gas installation, the site personnel must hold:

• OISD-mandated safety induction training
• Permit to Work (PTW) system training specific to that installation
• Competency certifications for hot work, confined space entry, and working at heights
• PPE compliance (FR clothing, ATEX-rated equipment in hazardous zones)

For equipment suppliers, HSE compliance means product safety data sheets, REACH/RoHS compliance for chemicals, and classification per IEC 60079 for electrical equipment in hazardous zones.

Contractors who lose time on HSE compliance issues during execution face liquidated damages and potential contract termination. Budget for HSE compliance costs and training when pricing oil and gas service contracts.

Bidovate aggregates tenders from all major oil and gas PSU portals in real time, with alerts for your registered vendor categories and automatic tracking of corrigendums and deadline changes, so you never miss a tendering window in this high-value sector.

Frequently Asked Questions

Do I need API certification to supply to ONGC or IOCL?

It depends on the product. For safety-critical equipment such as valves, wellhead components, pumps, and pipeline pipe, API certification (API 6A, 6D, 5L, 610, etc.) is mandatory. For non-critical materials (civil materials, office supplies, general consumables), API certification is not required. Check the technical specification in each specific tender to identify which standards apply.

Can MSME companies win oil and gas tenders?

Yes. Many recurring supply categories and maintenance AMCs are accessible to MSME companies. MSME companies registered on the Udyam portal receive EMD exemptions and price preference (up to 15% for Class I local suppliers under Make in India for certain categories). However, major EPC contracts and specialised equipment categories have financial and technical turnover requirements that effectively limit participation to medium and large companies.

How long does ONGC vendor registration take?

ONGC vendor registration typically takes 3-9 months for straightforward product categories with all documentation in order. Complex equipment categories requiring plant inspection by ONGC's team can take longer. The process can be expedited by ensuring all documentation (ISO/API certificates, financial statements, GST registration, product catalogs) is complete at the time of application.

What is the typical EMD for an oil and gas PSU tender?

EMD for oil and gas PSU tenders typically ranges from 1-3% of the estimated contract value, with a maximum cap (often Rs 1-5 crore depending on the PSU and contract size). For listed companies or companies with past satisfactory performance with the same PSU, some tenders allow EMD exemption on request. MSME companies with Udyam registration are exempt from EMD for tenders where the item falls within their registered category.

Can I participate in an ONGC offshore drilling rig tender without prior offshore experience?

Large offshore rig contracts require demonstration of prior offshore rig operation experience, typically 5+ years of operating similar rig classes in international or Indian waters, safety management system certification (ISM Code equivalent for offshore units), and OISD compliance certification. Without this track record, you cannot qualify directly. The practical path for a new entrant is to partner with an experienced international rig owner as a local agent or joint venture partner, gaining operational experience before attempting to qualify independently.
