An Indian tank builder set up to work outside India
HAIL (Hirva Anwesha Infratech Limited) designs, fabricates and erects API 650 and API 620 storage tanks for clients outside India, working either as a direct contractor to the plant owner or as a fabrication-and-erection subcontractor to the EPC main contractor holding the licence. Our engineering office and 33,000 sq.ft. fabrication workshop sit in Gujarat — within a few hours' road haul of Mundra, Kandla, Hazira, Dahej and Pipavav ports — which is the practical reason Indian tankage reaches overseas sites at competitive landed cost.
We are direct about our overseas record: our completed cross-border delivery is the IOCL petroleum terminal at Amlekhgunj, Nepal, described in detail below. Beyond that, what we bring to an international enquiry is code compliance, fabrication capacity and an erection organisation that has built tankage to the same standards your specification will call up. If you need a contractor with a decade of delivered projects inside your specific country, we will say so rather than waste your tender cycle. Separately from the company's own list, HAIL's leadership carries pre-HAIL delivery experience across the UAE, Oman, Bahrain, Kuwait, Qatar, Indonesia and Malaysia — relevant to how we plan, and stated as leadership experience rather than a HAIL reference.
Codes and certifications that travel
An overseas tank enquiry is usually filtered on standards before anything else. These are the codes we build to and the approvals we hold:
Tank & vessel codes
API 650 welded atmospheric storage tanks · API 620 low-pressure and cryogenic tanks · BS 7777 double-wall cryogenic · ASME Section VIII Division 1 pressure vessels under U-Stamp · IS 803 · API 653 for repair, alteration and reconstruction.
Welding & NDT
Welders qualified to ASME Section IX with documented WPS and PQR. Radiographic, ultrasonic, magnetic particle and dye penetrant examination; vacuum box testing on floor seams; full hydrostatic and pneumatic testing with charted records.
Quality & safety systems
ISO 9001:2015 quality management. Documented HSE system with JSA, permit-to-work discipline and toolbox routines — the regime that delivered a zero-incident record on hazardous-service work at Birla Copper, Dahej.
Third-party inspection
We work routinely under TPI. Lloyd's Register, Bureau Veritas, TÜV, RINA, SGS and owner-nominated inspectors are accommodated at stage-wise hold points, with material and weld traceability maintained throughout.
Coatings
Surface preparation to SA 2.5, coating systems to NACE and SSPC specification — epoxy, polyurethane, zinc-rich primer, intumescent fireproofing, internal linings and 3LPE for buried pipework, with DFT records.
Indian statutory (where relevant)
PESO SMPV(U) licence for pressurised storage and OISD compliance apply to Indian scope. They do not substitute for your local regulator, and we work to whichever national code your project is permitted under.
Proof of cross-border delivery — IOCL terminal, Amlekhgunj, Nepal
Our overseas reference is a complete petroleum terminal delivered for Indian Oil Corporation at Amlekhgunj, Nepal, contracted through Likitha Infrastructure Ltd. It is the clearest evidence of what we can put on the ground beyond our own borders, because it involved moving material, people and quality systems across an international frontier and commissioning to Indian Oil's standards.
Scope delivered: two IFR product storage tanks of 4,100 KL each (20 m diameter × 16 m height); two IFR transmix tanks of 250 KL each; two water storage tanks of 3,000 KL each (16 m diameter × 17.5 m height); structural steel erection with electroforged gratings; above-ground and underground piping with 3LPE protective coating; pump installation; and complete painting works. The terminal was completed and handed over.
What that project demonstrates for an overseas buyer is specific: internal floating roof construction to API 650, cross-border logistics and customs handling, an erection crew working away from home base for the duration, and a documentation trail acceptable to a national oil company.
How tanks actually reach your site
Storage tanks are not shipped assembled. We supply them as engineered knock-down (shipped-loose) packages: shell plates rolled to radius and match-marked, floor and annular plates, roof structure, staircases, handrails, nozzles, manways, and all internals crated and itemised against a packing list keyed to the erection drawings.
Workshop to port
Fabrication at our Kalol workshop — plate rolling to 50 mm, CNC profile cutting, MS, SS and duplex capability — then road haulage to Mundra, Kandla, Hazira, Dahej or Pipavav. Gujarat's port density is the reason this leg is short and predictable.
Container or breakbulk
Smaller tanks and internals ship in containers. Large-diameter shell courses and pre-rolled sections move as breakbulk or flat-rack cargo. We size the split to your port's handling capability and the inland route to site.
Marking and preservation
Every piece is stencilled to the erection sequence, with heat numbers and MTC references retained so third-party inspection can trace plate to certificate at your site, not just at ours.
Incoterms
We quote FOB, CFR, CIF or DDP depending on how much of the chain you want us to carry. Erection scope can be priced separately from supply, which suits buyers who already have a local civil and rigging contractor.
Erection: our supervision, your site
Supply-only rarely solves an owner's problem — the risk sits in the erection. We offer three models, and the right one depends on local labour law and your own resources.
Full erection crew
Fabricators, fitters, ASME IX qualified welders, riggers and QA/QC staff mobilised from India under an assignment structure, with our own supervision and quality system running the job end to end.
Supervision plus local labour
We send the erection manager, welding engineer and QA/QC inspector; the semi-skilled workforce is engaged locally. This is usually the fastest route through work-permit and local-content requirements, and we qualify local welders to ASME IX on arrival.
Technical assistance
Supply plus a resident engineer for setting-out, plumbness and roundness checks, weld procedure control, hydrotest supervision and sign-off, where your contractor performs the physical work.
Our owned lifting fleet — 200 MT, 100 MT, 50 MT and 20 MT cranes — sits in India, so overseas heavy lift is normally arranged locally or by your main contractor. We plan the lift study and rigging design either way.
The documentation package you receive
On international work the dossier is as scrutinised as the steel. A standard handover comprises: approved-for-construction drawings and as-builts; material test certificates to EN 10204 3.1 or 3.2; WPS, PQR and welder qualification records; the NDT map with radiographic film and interpretation reports; vacuum box and hydrostatic test records with charts; settlement survey and plumbness readings; coating DFT and holiday-test records; calibration certificates for test equipment; and the TPI release notes at each hold point.
Tank types and capacities we build for export
Atmospheric storage — API 650
Cone roof, external floating roof (EFR), internal floating roof (IFR) and double-deck floating roof (DDFR) tanks up to 110 m diameter, for crude, petrol, diesel, naphtha, kerosene, ATF, furnace oil, chemicals, acids and water.
Cryogenic and low-temperature — API 620 / BS 7777
Double-wall tanks for ammonia, liquid oxygen, liquid nitrogen, LPG, ethylene and butene, with perlite, foam glass or resilient blanket insulation systems.
Pressurised storage
LPG spheres and mounded bullets to ASME Section VIII and IS 2825, including petal fabrication, cathodic protection, leak detection and integrated fire safety.
Static equipment
ASME U-Stamp heat exchangers, process reactors, distillation columns, separators and pressure vessels in carbon steel, stainless, duplex and exotic alloys.
The leadership team behind HAIL carries management experience of 2,000+ tanks and 300+ projects across eight countries, including an international EPCC terminal contract valued at around USD 50 million, eleven crude oil tanks of 70,000 KL each, and twenty-seven product storage tanks totalling 1.38 million KL. That experience informs how we plan and sequence large tankage.
Regions we serve
Requirements differ sharply by region — accepted codes, shipping route, local content rules and how owners contract. We have written a page for each:
Middle East & GCC
UAE, Oman, Qatar, Saudi Arabia, Kuwait and Bahrain — short sea freight from Gujarat, approved-vendor realities and the subcontract route into operator-approved EPC contractors.
Africa
East and West African fuel terminals, tank farms and mining or fertiliser infrastructure — port routing, local-content structuring and supervision-led erection.
South & Southeast Asia
Nepal, Bangladesh, Sri Lanka, Vietnam, Indonesia and Malaysia — where our completed Amlekhgunj terminal is a direct, checkable reference.
What we need to quote
To return a firm price we need the tank schedule (number, diameter, height, capacity, service fluid), the governing code and any client specification, roof type, material of construction, design temperature and pressure, seismic and wind data for the site, nozzle schedule and general arrangement if available, the required scope split between supply and erection, delivery port and Incoterm, and the inspection and documentation regime. Budget enquiries are welcome with far less — diameter, height, service and destination are enough for an indicative figure.

Frequently asked questions — overseas tank construction
Do you build storage tanks for projects outside India?
Yes. We fabricate and erect API 650 and API 620 storage tanks for overseas projects, working either directly for the plant owner or as a fabrication and erection subcontractor to the EPC main contractor. Our completed cross-border delivery is the Indian Oil petroleum terminal at Amlekhgunj, Nepal, comprising two 4,100 KL IFR product tanks, two 250 KL transmix tanks and two 3,000 KL water tanks, plus structural steel, 3LPE-coated piping and painting.
How is a storage tank shipped to an overseas site?
As an engineered knock-down or shipped-loose package. Shell plates are rolled to radius and match-marked, floor and annular plates cut to size, and the roof structure, staircases, handrails, nozzles, manways and internals crated against a packing list keyed to the erection drawings. Smaller tanks ship in containers; large-diameter shell courses move as breakbulk or flat-rack. We load from Mundra, Kandla, Hazira, Dahej or Pipavav, all within a short road haul of our Gujarat workshop.
Which international codes does HAIL build to?
API 650 for welded atmospheric storage tanks, API 620 and BS 7777 for low-temperature and cryogenic tanks, API 653 for repair and reconstruction, ASME Section VIII Division 1 under U-Stamp for pressure vessels, and IS 803. Welders are qualified to ASME Section IX with documented WPS and PQR. Quality management is certified to ISO 9001:2015 and coatings follow NACE and SSPC specifications.
Will you send an erection crew to our country?
Yes, under one of three models. We can mobilise a complete crew of fitters, ASME IX welders, riggers and QA/QC staff from India; or send supervision only — erection manager, welding engineer and QA/QC inspector — with the workforce engaged locally, which usually moves fastest through work-permit and local-content requirements; or provide a resident engineer for technical assistance while your contractor performs the work. Where local welders are used we qualify them to ASME Section IX on arrival.
Are you an approved vendor for ADNOC, Saudi Aramco or similar operators?
We do not currently hold those operator approvals, and we would rather state that plainly than have it emerge during prequalification. On projects for operators that maintain closed approved-vendor lists, we work as a fabrication and erection subcontractor to an EPC main contractor who already holds the approval — a normal and accepted structure. Where an owner is willing to sponsor vendor registration directly, we will complete the process.
What documentation is handed over at completion?
Approved-for-construction drawings and as-builts; material test certificates to EN 10204 3.1 or 3.2; WPS, PQR and welder qualification records; the NDT map with radiographic film and interpretation reports; vacuum box and hydrostatic test records with charts; settlement, plumbness and roundness surveys; coating DFT and holiday-test records; calibration certificates; and third-party inspection release notes at each hold point.
Can third-party inspectors witness fabrication at your workshop?
Yes, and it is normal on export work. Lloyd's Register, Bureau Veritas, TÜV, RINA, SGS and owner-nominated inspectors are accommodated at stage-wise hold points agreed in the inspection and test plan before fabrication starts. Material and weld traceability is maintained so plate can be traced to certificate at your site, not only at ours.
What is the largest tank you can supply for export?
We build API 650 tanks up to 110 m diameter. For export the practical constraint is rarely our fabrication capacity — it is the destination port's handling capability and the inland route to site. We size the shipping split around those limits, so very large tanks are supplied as more, smaller pieces with a longer field weld schedule rather than being ruled out.
