Project Cargo Handling: Moving Oversized and Heavy-Lift Shipments Safely

Project cargo is any consignment that will not move on standard equipment: over-dimensional, over-weight, or requiring specialist handling. Transformers, turbines, pressure vessels, plant machinery, wind components, industrial boilers.

The defining characteristic is that the route determines the plan, not the other way round.

Start with the route survey

Before equipment is booked or a vessel selected, the physical path from port to site must be verified end to end. A survey checks:

• Vertical clearance — flyovers, footbridges, power lines, tunnels, tree canopy
• Horizontal clearance — carriageway width, turning radii at junctions, roundabouts
• Load bearing — bridge and culvert capacity against the combined axle load
• Obstructions — toll plazas, medians, level crossings, utility poles
• Site access — the final hundred metres, which is where surveys most often fail

Where an obstruction is found, the options are a diversion, temporary removal of the obstruction with the relevant authority's permission, or a different discharge port. All three take time to arrange, which is why the survey comes first.

Permits take longer than you think

ODC movement in India requires approvals that vary by state and by route:

• RTO permits for each state the consignment passes through
• NHAI approval for national highway movement
• Police escort arrangements, often with mandated night-only movement windows
• Utility clearances where power or telecom lines must be temporarily raised
• Railway approval for level crossings

Each authority works to its own timeline. Applications should run in parallel, and they should start as soon as the route survey is complete — not once the cargo has landed.

Budget six to eight weeks for permits on a multi-state ODC movement. Compressing this is the single most common cause of project cargo overruns.

Equipment selection

The trailer is chosen from the cargo dimensions, the weight, the axle-load limits on the route and the lifting arrangements at both ends.

• Multi-axle hydraulic trailers — distribute load, steer independently, handle very heavy pieces
• Low-bed and semi-low-bed trailers — reduce total height for clearance-constrained routes
• Modular SPMTs — self-propelled units for the heaviest and most awkward pieces
• Girder bridge trailers — for exceptionally long items

The lifting plan

Loading and discharge need a documented plan covering lift points, sling and shackle specification, crane capacity at the required radius, ground bearing pressure under outriggers, and the sequence of operations.

Lifting points must be confirmed with the manufacturer. A vessel lifted at the wrong point can be damaged in ways that are not visible until commissioning.

Customs considerations

Project cargo brings its own clearance complexity:

• Multiple items across multiple containers or breakbulk lots may belong to a single project and need consistent classification
• Project Import benefits under Heading 9801 can significantly reduce duty, but require registration of the contract with customs before importation
• Temporary imports of construction equipment may qualify for ATA Carnet treatment
• Examination of oversized cargo needs to be planned — it cannot simply be moved to an examination area

Project Import registration in particular is worth investigating early. The duty saving is substantial and the registration must precede the import.

Insurance

Standard marine cover is rarely adequate. You want a policy that covers the full scope: ocean leg, discharge, inland transport, storage and, where relevant, erection at site. Ensure the sum insured reflects replacement cost and the delay-in-start-up exposure if the equipment is on a project critical path.

A realistic timeline

The permits column is what people underestimate.
