Enclosed ground flares for an LNG export terminal in Louisiana.

Four enclosed ground flare systems, each a combustion chamber about 20 m across and 46 m high, built in our works, trial-assembled in full and shipped across the ocean.

Systems: 4 enclosed ground flares
Each chamber: About 20 m dia, 46 m high
Steel: About 2,200 T
Destination: Louisiana, USA
Status: In execution

The project

An LNG terminal burns off gas safely inside enclosed chambers. Each chamber had to arrive as a kit of panels and frames that would bolt up on the other side of the world without a single mismatched hole.

What we made

Detail design to the licensor’s drawings
Shell panels rolled and numbered by ring
Internal column and ring-girder frame
Noise shrouds, wind fences and platforms
Studs welded for the ceramic tile insulation
Painting and export packing

How we built it

Three-roll pinch cum pyramid plate rollsShell panels rolled to the chamber radius.
Kotec newRun10DX CNC beam drilling lineFrames and panel borders drilled on 3 faces, CNC accurate.
Deratech Supera-H 12030 fibre laserPlates and gussets cut on the 20 kW fibre laser.
Conveyor shot-blasting lineBlasted and painted in house, with a coating inspector on the floor.

Every chamber is trial-assembled to full height in our 30 m bay before dispatch, so fit-up problems are found in Ahmedabad, not on site.
