A project cargo move is a single engineering problem stretched across several thousand kilometres. One reactor, one transformer, one mill stand, one pre-assembled module — it cannot be split, it will not fit in a container, and every party that touches it has to work to the same set of numbers. The sequence below is roughly how a heavy lift actually moves, and the reason the sequence matters is that a decision taken late in it usually forces a change to something decided early.
Project cargo starts with feasibility, not with a price
The first real question is not “what will it cost” but “can it get there at all”. That is answered by establishing four things: the finished dimensions and weight of the built item, not the drawing; the lifting points and the centre of gravity; the route from the fabrication shop to the port and from the discharge port to the site; and the receiving capability at the site itself.
Route survey on both inland legs is physical. Somebody drives it, measures every vertical clearance, checks each bridge and culvert against the intended axle configuration, records turning radii at junctions and at the site gate, and photographs what will have to be moved, lifted or dismantled. The last kilometre defeats more project cargo shipments than the highway does.
The site-end questions belong in the same survey: is there hardstanding for crane outriggers, is there swing space, is there a laydown area, is the foundation ready to receive on the day the cargo arrives.
The lifting study
Every point at which the item leaves the ground gets engineered: out of the shop, onto the trailer, off the trailer at the port, onto the vessel, off the vessel, onto the destination trailer, and onto the foundation. Each of those is a lift plan with a crane or a pair of cranes in tandem, a rigging arrangement, a sling and shackle schedule rated for the load with the correct safety factor, spreader beams where side loading on the lugs must be avoided, and a ground bearing pressure check under the crane.
The lifting lugs on the item are designed by the fabricator for a specific rigging geometry. If the sling angle differs from that geometry, the lug load changes and the design assumption is void. This is why the lift study and the fabrication drawings have to be reconciled early, and why “we will decide the rigging at site” is the sentence that precedes a bent lug.
Packing and preservation
Breakbulk and flat rack cargo travels exposed to weather, salt air and the accelerations of a moving ship. Packing for that is different from packing for a container.
- Machined surfaces and flanges protected with preservative and covered; nozzles blanked.
- Moisture control where the item is crated — desiccant, vapour barrier, and vents where condensation is the greater risk.
- Cradles and saddles that transfer load into the structure of the item rather than into its shell, sized for the trailer deck and for the vessel’s tank top or hatch cover.
- Lashing and jacking points marked and structurally adequate, so the vessel’s crew do not improvise onto the wrong part of the item.
- Shock and tilt indicators where the equipment is sensitive and the supplier’s warranty depends on evidence.
- Marking of centre of gravity, sling positions, weight and dimensions on the outside, in a form legible to people who have not read the file.
The inland leg
The trailer choice follows from the survey, not from availability: flatbed where only width or length is oversize, semi-low or low bed where vertical clearance binds, hydraulic axle lines where gross weight must be spread across a bridge rating or where the deck height has to change en route. Oversize permissions are arranged per state, with the road-owning authority and utility clearances that the route needs, and with escorts and movement windows as the issuing authority requires. From Gujarat, project consignments commonly move to Mundra, Pipavav or Kandla/Deendayal, and the choice among them is as much about which port can physically handle the lift as about sailing frequency. The permitting and survey detail is covered in our guide to road movement of oversize loads.
Port handling and the heavy-lift berth
Not every berth can take a heavy lift. What decides it is quayside crane capacity at the required radius, or the availability of a mobile harbour crane or the vessel’s own gear; the bearing capacity of the quay apron under a crawler crane; laydown space and how long the port will allow the item to occupy it; and the gate and internal road geometry for the trailer to reach the berth at all.
Two arrangements exist. Direct delivery means the trailer arrives alongside and the item goes straight from trailer to vessel, which minimises handling and storage but requires the vessel and the trailer to be in the same place at the same time. Pre-delivery to a laydown area de-risks the road leg but adds a lift and a storage exposure.
Choosing the vessel
| Option | How the cargo travels | Best when |
|---|---|---|
| Flat rack / open top | Secured to a container-frame base on a container vessel | Cargo is over-dimensional but within the weight and footprint a flat rack can take; container service frequency is worth having |
| Breakbulk / multipurpose vessel | Stowed in hold or on deck, lifted by ship’s gear or shore crane | Cargo is too heavy or too large for flat rack; heavy-lift derricks are needed |
| Heavy-lift vessel | Purpose-built, high-capacity cranes, strengthened decks | Very heavy single pieces, or several pieces needing engineered stowage |
| RoRo | Rolled on wheels or on a roll trailer | Self-propelled or wheeled units, or where lifting the item is the risky part |
Flat rack is usually the cheapest route when it genuinely fits, because it rides a liner service. The moment a piece exceeds what a flat rack can carry, the comparison changes: breakbulk and heavy-lift sailings are less frequent, and the schedule has to be built around a sailing window rather than a weekly service. Choosing the equipment is part of the ocean freight decision, and for multi-piece consignments the mode split between sea, road and rail is worth modelling as a whole in multimodal terms.
Stowage and lashing
Sea fastening is engineering, not strapping. The vessel’s operator prepares a stowage plan and a lashing calculation based on the expected accelerations for the route and season, the item’s weight and centre of gravity, and the strength of the deck or tank top beneath it. Welded stoppers, chocks, timber bedding and wire or chain lashings are specified with ratings, and on significant lifts an independent marine warranty surveyor reviews the plan and attends the loading, issuing an approval that the cargo underwriters will usually want to see. Approving the method statement before loading day is what keeps the vessel from waiting.
Insurance
Standard marine cover written for containerised goods does not sit well over a project move. What matters is that the cover follows the cargo through every handling step including inland transit and lifting, that the sum insured reflects landed value rather than invoice value alone, that any warranty surveyor requirement is met so the cover is not prejudiced, and that delay-in-start-up exposure is considered where the item is on a construction critical path. Declare the real values and the real method; a claim tested against a method statement that was never followed is a difficult claim.
Site delivery
The final move is often the tightest. The destination-side route survey is redone close to the date because roads change. The site crane is booked against a lift plan, the ground under it is prepared and verified, the foundation and anchor bolts are confirmed ready, and the sequence of trailer positioning, rigging, lift and set-down is agreed with the site team in writing before the convoy leaves its last halt. Where the receiving structure is not ready, a planned interim storage point near site is cheaper than an unplanned one.
