Dhamra LNG Terminal: India Cryogenic Pipe & Fitting Demand

2. What a 5 MTPA Regas Terminal Physically Requires

A standard LNG-import terminal of this size physically contains:

• 2 LNG storage tanks (typically 160,000 - 180,000 m³ each, full-containment)
• LNG unloading arms at the jetty
• BOG (boil-off gas) compressors + recondenser
• Submerged combustion vaporizers (SCV) or open-rack vaporizers (ORV) for regasification
• Send-out pipeline to the national grid

Translate that into the typical pipe / fitting BOM:

• 9% Ni (ASTM A553) for cryogenic LNG service (storage outlet, vaporizer feed)
• 304 / 316L SS (ASTM A312 / A403) for BOG and N₂ purge
• Low-temp carbon steel (A420 WPL6 fittings, A350 LF2 flanges) for send-out gas after vaporization
• ASME B16.9 elbows / tees / reducers
• ASME B16.5 RTJ flanges for send-out pipeline tie-in
• ASME B31.3 process piping code for plant
• ASME B31.8 for the cross-country send-out pipeline

3. The Pipeline-Construction Lesson

Dhamra's start-up history is instructive:

• Original target: mid-2021
• Revised: mid-2022 (COVID delays)
• Revised again: 2023 (associated trunk-pipeline delays)
• Commissioning: H1 2023
• First cargo: April 2023
• Commercial operations ramped through 2024 to ~ 50 % utilisation by early 2025

The delays were driven largely by the associated trunk pipeline construction, not by the terminal itself.

For LNG-import projects globally, the connecting trunk-line scope (and its fittings, induction bends, hot-tap tees, mechanical connectors) is often the critical path, not the storage tanks or the regas equipment. Tanks are well-known engineering. Connecting 200+ km of cross-country pipeline through populated land — that is the schedule risk.

For pipe-fitting suppliers, this means:

• Hot-tap and connection fittings are time-sensitive line items
• Induction bends for cross-country pipeline are long-lead
• Pipeline metering station fittings and launching/receiving traps are bespoke

4. Utilisation Reality and What It Means for Buyers

Dhamra's ~ 25 % utilisation in 2024 meant slower fittings replacement / MRO demand at first — but the ramp to ~ 50 % by early 2025 (and ~ 55 % later) accelerates spares and turnaround cycles.

Expansion from 5 MTPA to 10 MTPA is "not imminent" per CEO Lamba (Feb 2025), but it is the next demand wave to watch.

5. Takeaway for International Fittings Suppliers Eyeing India

India's LNG-import market is following a multi-terminal expansion path. Currently planned/under-construction Indian regas terminals include Jafrabad (Swan Energy), Chhara (HPCL), Mundra (Adani-Mundra LNG), Dhamra-2 expansion (when triggered), and several smaller projects.

For international suppliers:

• BIS / IBR compliance is mandatory for any pressure equipment going into Indian sites — Bureau of Indian Standards mark + Indian Boiler Regulations approval
• IOCL / GAIL / Petronet AVL approval cycles typically 6-12 months
• Vendor qualification on a current Tier-1 terminal (like Dhamra) significantly de-risks future Indian regas wins
• Site documentation in English (mandatory) + sometimes Hindi
• Local agent typically required for Indian PSU procurement
