Tanker deck at night under a clear starfield

Key takeaways

  • Define the programme each proposal must serve before ranking hire rates.
  • Apply the actual delivery, duration and redelivery conditions.
  • Add only costs retained under the specific proposal and comparison scope.
  • Check whether the offers provide equivalent usable employment.
  • Keep contractual interpretation separate from the illustrative arithmetic.

Begin with the service the charterer needs

The charterer should identify the cargo programme, required availability and intended ending position. Each vessel proposal can then be assessed against that requirement.

Do not assume two daily hire indications purchase the same service. The vessels may be offered on different opening conditions or for different durations. Their permitted use and the responsibilities retained by the charterer also require review under the actual terms.

The comparison should state what the business needs to accomplish and whether each proposal can accomplish it. A low rate for an unsuitable or unavailable vessel is not a usable alternative. Establish feasibility before trying to repair the price comparison with financial adjustments.

Where an alternative requires a different programme, show that change openly. It may be worthwhile, but it should not be presented as equivalent employment simply because the cargo volume appears similar.

Put delivery and redelivery into the time boundary

Identify when the model begins counting the charterer's relevant commitment and when it ends. Use the actual proposed terms and supported operating plan, with qualified interpretation where their effect is uncertain.

The desired cargo movement may occupy only part of that commitment. Additional time can be needed within the proposed arrangement before the cargo work begins or after it ends. Whether a particular period is payable or which party bears a related cost depends on the actual agreement, not a universal rule in this article.

Keep the operational estimate and contractual basis connected. A physical completion date does not by itself establish the end of a payment obligation. Equally, do not add time merely because it appears in a generic model if the actual arrangement does not support that treatment.

The analyst's task is to use the agreed or clearly assumed basis consistently, not to decide legal rights from a spreadsheet label.

Use a like-for-like comparison table

Comparison fieldQuestion to answer for each offerWhy it matters
Programme servedWhich cargo movements and availability requirements fit?Establishes whether the alternative is useful
Delivery basisWhere and when does the relevant commitment begin?Defines the starting boundary
DurationWhat paid or otherwise relevant time is assumed?Converts a daily rate into a commitment
Redelivery basisWhat ending condition must the plan satisfy?Captures the full proposed scope
Retained costsWhich necessary expenses remain with the charterer?Prevents comparison of incomplete totals
Conditional termsWhich facts could change the offer or its use?Identifies the actual decision uncertainty

Populate the table from the proposals. Do not use a standard-form name as a substitute for checking the negotiated terms and amendments that apply to the employment.

Illustrative case: higher hire, lower complete cost

ILLUSTRATIVE fictional offers. A charterer compares two feasible proposals serving the same defined programme. For this model only, all listed days are payable at the stated hire rate, and the additional costs belong to the charterer under the fictional proposals.

Offer A charges USD 18,000 per day over 40 days. It requires USD 80,000 of additional delivery-related services and USD 100,000 of redelivery-related services within the model boundary.

Offer B charges USD 20,000 per day over 35 days. Its corresponding additional services cost USD 40,000 and USD 60,000. These amounts are invented and do not represent customary cost allocations.

Cost componentOffer AOffer B
Daily hireUSD 18,000USD 20,000
Payable days in the model4035
Hire totalUSD 720,000USD 700,000
Delivery-related servicesUSD 80,000USD 40,000
Redelivery-related servicesUSD 100,000USD 60,000
Complete listed costUSD 900,000USD 800,000

B's daily rate is higher, yet its hire total is USD 20,000 lower because the model includes fewer paid days. Its other listed services cost USD 80,000 less, making the complete difference USD 100,000 in B's favour.

The result follows only from the defined offers. If B cannot actually complete the programme within its assumed duration, or if a necessary service is omitted, the comparison must change. The table is not a reason to prefer higher daily rates generally.

Check whether the duration difference is real

A shorter estimate deserves scrutiny because it can drive both cost and availability. Ask which supported difference produces it. Is the delivery position different? Does the operating programme differ? Are the relevant service windows confirmed?

Do not compare a cautious duration for one ship with an optimistic duration for another without explaining the basis. Use comparable confidence and scope, or show separate scenarios that reveal the uncertainty.

Also distinguish the expected duration from any contractual commitment. If the proposal contains a minimum period or another relevant condition, assess its actual effect with the appropriate review. An operational estimate below that commitment should not automatically reduce the modelled payment.

Where the alternative requires extra repositioning outside the apparent programme, include the supported time and costs in the appropriate boundary. Otherwise the lower total may be created by stopping the calculation too early.

Keep retained expenses consistent

The hire total is only one component of the comparison. Identify the necessary expenses that remain with the charterer under each actual offer. Do not assume the same allocation across proposals simply because both are described as time charters.

Check that every additional cost has a purpose. An allowance for a service already included elsewhere can duplicate expenditure. An omitted necessary service can make a proposal appear artificially attractive.

Where a cost is conditional, state the event and basis that make it relevant. Keep the base commitment and conditional scenario separate rather than hiding both inside an unexplained contingency.

The final recommendation can then explain whether the advantage comes from hire, duration, service scope or a combination. This is more useful for negotiation than asking only for a lower headline daily rate.

Interpret the remaining trade-offs

Even a complete cost comparison may leave differences in flexibility or timing. An offer might better fit the programme's uncertain cargo sequence, while another has a lower supported cost but a narrower usable scope.

State those differences without inventing a monetary value for them. If the business has an approved method for valuing an option, apply it transparently. Otherwise show the cost comparison and the qualitative reason the decision maker might accept a premium.

The recommendation should identify the condition that could reverse the ranking. That might be a revised duration, a changed service scope or confirmation that an alternative is no longer available. The comparison remains useful only while its underlying offers and assumptions remain applicable.

Common mistakes

One mistake is ranking hire rates before checking whether the vessels serve the same programme. Another is comparing expected operating days with a different contractual commitment without reconciling them.

A third error is stopping the calculation at cargo completion while ignoring the actual ending condition. Finally, do not assume standard cost allocations or payment treatment without reviewing the relevant agreed terms.

Frequently asked questions

Is the lowest daily hire the lowest employment cost?

Not necessarily. Duration and retained services can reverse the ranking, as the fictional example demonstrates.

Should delivery and redelivery costs always be added?

Include the costs relevant to the actual proposal and chosen boundary. Their allocation is not universal and should not be inferred from the example.

How should uncertain duration be handled?

Use supported estimates and show coherent alternatives where the uncertainty could change the result. Keep operational timing distinct from the actual payment commitment.

Can different vessel proposals be compared at all?

Yes, if their ability to serve the requirement and their complete relevant costs are made clear. Material differences should remain visible rather than being forced into apparent equivalence.

What should a negotiation focus on after this comparison?

The driver of the complete difference: rate, duration, service scope or a specific condition. A smaller headline rate reduction may matter less than resolving a consequential scope or timing issue.
