Refinery Heavy Lift & Column Erection Specialist

Heavy lifts that other contractors won't underwrite

Erecting a 60-metre, 350-ton column inside an operating refinery is not a crane job — it is an engineering exercise. Ground bearing capacity, outrigger spreads, tail-crane choreography, weather windows, exclusion zones, PTW interfaces with the operating unit, and a millimetre-accurate landing on the foundation bolts: each one has to be planned, signed and underwritten before the boom comes out. As a specialist column erection contractor, HAIL has done it more than 40 times — including 350+ ton lifts at 60-metre elevation — without a single dropped load incident. Our reactor erection and refinery column installation teams operate across Gujarat's industrial belt from Vadodara to Jamnagar, Hazira, and Dahej.

What we erect

Owned crane fleet

For super-heavy lifts beyond owned capacity, we work with India's leading heavy-lift crane suppliers under pre-arranged tie-ups, so the schedule never slips waiting for a crane.

Engineered lift planning

• Ground bearing capacity (GBC) survey and outrigger pad design.
• Crane configuration drawings, boom-and-jib geometry, capacity-vs-radius checks.
• Rigging gear take-off — slings, shackles, spreader bars certified to load.
• 3D lift studies for tandem and tail-crane operations.
• Method statement, JSA, PTW interfaces and HSE briefing pack.
• Weather window and wind-speed cut-offs.

Erection methodology — from laydown to first bolt

Every column erection and reactor erection follows a documented, auditable sequence that our engineering and rigging teams have refined over 40+ critical lifts. The methodology applies equally to distillation columns, hydroprocessing reactors, FCC regenerators, kilns, boilers, and heavy vessels.

1. Pre-lift engineering: Lift study with centre-of-gravity calculation, dynamic load factors, wind load analysis, and crane capacity-vs-radius verification. For tandem lifts, we model boom interference zones and synchronised hoist-speed envelopes.
2. Ground preparation: Soil bearing capacity assessment at every outrigger location. Crane pads — steel plates on compacted gravel or reinforced concrete — are designed to distribute outrigger loads below allowable ground pressure. On soft soils or near underground services, we use load-spreading mats with monitoring.
3. Rigging and tackle: All slings, shackles, trunnions, spreader beams, and lifting lugs are selected for a minimum 5:1 safety factor. Certificates are verified, and any item showing wear, deformation, or corrosion is rejected. Rigging gear take-off is issued as a formal document signed by the lifting engineer.
4. Laydown and pre-assembly: Equipment is received, inspected for transport damage, and positioned on sleepers in the laydown area. Internals, tray support rings, nozzle reinforcement pads, and instrumentation brackets are pre-installed at ground level wherever possible to minimise work at height.
5. Crane set-up and function test: The crane is positioned per the lift-study plot plan. Boom length, jib configuration, and counterweight are set. Pre-lift function checks cover all motions, limit switches, load moment indicator (LMI), anti-two-block device, and emergency stop.
6. Lifting and uprighting: The column is rigged at engineered lift points. A tail crane lifts one end while the main crane hoists the top, uprighting the column from horizontal to vertical in a controlled swing. Wind speed is monitored continuously — operations abort above 30 km/h.
7. Setting and alignment: The column is lowered onto anchor bolts on the foundation pedestal, guided by tag lines and a banksman. Nozzle orientation is checked against the piping layout north arrow. Precision alignment is verified with spirit levels and laser instruments before anchor bolts are torqued to specification.
8. Grouting and handover: Non-shrink epoxy grout is poured under the base plate and cured for 24-48 hours. Rigging is removed only after bolting is complete and grout has gained strength. The erected equipment is formally handed over to the piping and mechanical team.

Equipment types we erect

As a full-scope heavy lift crane contractor, HAIL erects every category of static process equipment found in refinery, petrochemical, fertiliser, and power plant environments:

• Columns and towers: Crude distillation columns, vacuum columns, fractionation columns, absorber towers, stripper columns, debutanisers, and splitters — heights from 15 metres to 60+ metres.
• Reactors: Catalytic reactors, hydrocracking reactors, hydrotreating reactors, FCC regenerators, ammonia converters, and reformer tubes. Reactor erection often involves tight clearances in existing process units.
• Heat exchangers and air-fin coolers: Shell-and-tube exchangers up to 100 tonnes, plate-type exchangers, air-fin cooler banks, and condenser bundles. We also perform bundle pulling and re-tubing.
• Drums and vessels: Knock-out drums, reflux drums, surge drums, separators, accumulators, and flash drums — both vertical and horizontal orientations.
• Boilers and HRSGs: Package boilers, waste-heat recovery boilers, and HRSG modules for power and co-generation plants.
• Flare stacks and chimneys: Self-supporting and guyed flare stacks erected by lift-and-stand or sectional step-up jacking method.
• Pipe rack modules and structural steel: Pre-fabricated pipe rack bents, equipment platform modules, and large structural assemblies for modular construction and refinery revamp projects.

Safety practices for heavy lift operations

HAIL's safety record — zero dropped loads across 40+ critical erections — is built on non-negotiable procedures enforced at every site, whether it is a greenfield plot or a live refinery unit in Vadodara, Jamnagar, Hazira, or Dahej:

• Permit to Work (PTW): Every lift inside an operating plant carries a formal PTW covering crane exclusion zone, overhead power lines, adjacent live equipment, hot-work clearance, and emergency evacuation routes.
• Toolbox talk and JSA: A job safety analysis is conducted before each critical lift. The toolbox talk covers roles (crane operator, rigger, banksman, supervisor), communication signals, wind-speed cut-offs, and abort procedures.
• Engineered lift study: No critical lift proceeds without a signed-off lift study. This document covers equipment weight, CG location, crane capacity chart verification, rigging geometry, and dynamic factors.
• Third-party verification: For super-critical lifts, HAIL engages RINA Consulting or an equivalent independent verifier for rigging design review and lift-study audit.
• Real-time weather monitoring: Anemometers are deployed at boom tip height. Operations pause when sustained wind exceeds 30 km/h or gusts exceed 40 km/h.
• Post-lift inspection: After every erection, the equipment is inspected for lifting damage — dents, scratches on machined surfaces, weld cracks at lug locations — before rigging removal.

Locations we serve

HAIL's column erection contractor India operations are headquartered in Vadodara, Gujarat, with active project reach across India's western industrial corridor. Our crane fleet and erection crews have mobilised to refineries and plants in Jamnagar (Reliance Jamnagar complex), Hazira (ONGC, L&T, Shell corridor), Dahej (PCPIR petrochemical zone), Koyali (IOCL Gujarat Refinery), Barauni (IOCL Bihar), and multiple chemical and fertiliser sites across Gujarat, Rajasthan, and Maharashtra. As a Vadodara-based heavy lift crane contractor, we offer faster mobilisation and lower transit costs for projects across western India.

Reference projects

• IOCL Barauni Refinery — Coker-B Revamp: heavy equipment erection, multi-discipline EPCC inside live unit.
• IOCL Gujarat Refinery — N-Butanol Project for Thyssenkrupp Industrial Solutions: equipment fabrication and erection inside a live refinery.
• 40+ critical heavy equipment erections across refinery, fertiliser and chemical industries — leadership-led.
