Why Two Similar Freight Offers May Produce Different Final Voyage Costs

A rate is only one part of the offer

Two freight quotations can differ by only a few dollars per tonne and still expose the charterer to very different final costs. A headline rate is meaningful only when the offers are compared on the same cargo quantity, ports, laycan, loading terms, discharge terms, laytime basis and vessel assumptions. If one owner has priced a fast terminal and another has allowed for a slower operation, the numbers are not directly comparable.

Check what the freight includes

FIOS, FIOST, liner in, liner out and hook terms allocate cargo-handling expenses differently. The charterer must identify who pays for stevedoring, trimming, lashing, dunnage, crane hire and movement between storage and ship’s side. An apparently higher freight rate may include an operation that is excluded from the cheaper offer.

Laytime has a price

Loading and discharge rates should reflect the terminal’s real performance, not an optimistic brochure figure. Working hours, weekends, weather interruptions, congestion and cargo readiness affect the time the vessel remains in port. A low rate combined with tight laytime and high demurrage can be considerably more expensive than a slightly higher rate with realistic allowances.

The ship must fit the entire voyage

Deadweight is not enough. Draft, beam, length, air draft, hatch dimensions, hold geometry, crane capacity and outreach may determine whether the vessel can use the nominated berths and handle the cargo. Any need to shift berth, lighten the vessel, hire a floating crane or change the stowage plan must be included in the commercial comparison.

Compare offers on a voyage-cost sheet

The practical approach is to place every offer on one sheet and calculate freight, port handling, estimated time, likely demurrage exposure, agency costs and any vessel-specific extras. Kiev Shipping Ltd applies this method when providing ship chartering services, because the lowest number in the freight column is not necessarily the lowest transportation cost.

Conclusion

A freight offer should be treated as a package of assumptions. The best commercial choice is the offer whose vessel, terms and time allowances match the real cargo and ports, not automatically the one with the lowest rate.
