Key takeaways

  • Compare the same accepted grades and required quantities in every option.
  • Identify whether a package discount depends on buying both grades.
  • Include separate service costs created by a split purchase.
  • Confirm that the chosen combination can actually fit the call.

Fujairah context: different grades within the supply network

The port identifies dedicated FOTT bunker-barge berths serving MGO and low-sulphur fuel-oil operations. Port of Fujairah oil facilities

The presence of this infrastructure does not confirm a particular supplier's inventory or delivery window. For the buyer, the useful question is whether the offered grade combination reaches the vessel on the agreed basis, through one package or separately defined supplies.

For a current transaction, the package comparison basis is not provided; obtain current verified information. Record each grade's confirmed quantity, price scope and delivery conditions, including any dependency between the quoted lines.

Identify the dependence between price lines

A supplier may quote each grade separately while making the overall commercial offer conditional on buying the package. Ask whether either line can be selected alone at the same price. Do not assume that a quotation formatted as separate rows creates independent options.

Conversely, a package may contain a weak price for a smaller grade that is obscured by an attractive main-grade price. Calculate the full amount instead of ranking the offer solely on the largest parcel's unit rate.

The comparison should use the vessel's appropriately confirmed requirements. Changing the grade mix merely to make a package appear attractive can disconnect the calculation from the actual purchase decision.

Calculate the complete combination

The following example assumes that both fictional grade descriptions meet the accepted specifications. All offers are assumed available for the intended call; actual feasibility still requires confirmation.

ILLUSTRATIVE: A combined offer covers 500 tonnes of VLSFO at $600 per tonne and 80 tonnes of MGO at $850 per tonne, with the defined delivery service included. Its total is $368,000: $300,000 plus $68,000.

Separate offers provide VLSFO at $590 per tonne and MGO at $840 per tonne. Fuel alone totals $362,200: $295,000 plus $67,200. However, the split arrangement adds $9,000 of separately quoted service costs, taking its total to $371,200.

The combined package is therefore $3,200 lower on the included basis. The split's fuel saving is $5,800, so it only remains lower-cost if its additional service expense is below that amount, with all other assumptions unchanged.

The result is specific to the defined package. It does not imply that combining suppliers is always better, or that the additional service cost has any particular prevailing Fujairah value.

A comparison with one unconfirmed grade is still conditional. Do not count its saving as secured while the missing supply may change the entire arrangement.

Test quantity changes before accepting a discount

A package initially built around an estimated MGO quantity may need revision when the vessel finalises its requirement. Ask whether the quoted unit prices, minimums and included services survive the new mix.

Likewise, a split option can lose its economic advantage if the smaller order attracts a different service charge. Refresh the complete comparison rather than changing only one fuel-price cell.

Keep the reason for any revision clear. A higher total caused by a larger required quantity is different from a higher price for the same purchase. The desk should be able to explain each effect to the decision-maker.

Fictional case: the package survives a smaller distillate order

A fictional operator seeks both VLSFO and MGO for a Fujairah call. Its first worksheet combines the lowest quoted unit price for each grade without checking whether those prices are independently selectable.

The enquiry reveals that one attractive VLSFO line requires the full package. The vessel then confirms a smaller MGO requirement. The buyer obtains revised offers for the actual quantities and includes the separate service expense of splitting the purchase.

The chosen package is based on the usable revised terms. The desk preserves the grade-level evidence so that a later invoice can be reconciled without treating the combined total as an unexplained lump sum.

Common mistakes

Do not assemble a theoretical purchase from price lines that cannot be selected independently. Other errors include ignoring extra services, evaluating the whole package on one grade and preserving an old discount after the quantity mix changes. Infrastructure availability does not prove the quoted combination is ready for the call.

Frequently asked questions

Is a combined supplier always less expensive?

No. Compare the complete, feasible propositions at the actual required quantities.

Can separate quotation rows be accepted independently?

Only if the supplier's terms support that interpretation. Confirm any package condition.

Should a quantity change trigger a fresh comparison?

Yes, where it affects price, minimums, inclusions or delivery conditions.

Does the example establish a current Fujairah service charge?

No. Every numerical input is fictional and illustrates the effect of splitting a purchase.
