Buying time
to create competition.

In an emergency fuel purchase, time can change who is able to supply. Making that possibility useful requires a clear account of inventory, unloading, commercial rights and the suppliers who can actually compete.

A buyer facing a gas shortfall has two urgent decisions: secure another cargo and decide whether to reduce or substitute current gas use. Those decisions are connected. Slowing consumption may postpone the shortage long enough for another supplier to become a practical option. The value of an operating action can therefore include the competition it makes possible.

That is the question behind my research-stage paper, Buying Time to Create Competition: Demand Flexibility and Emergency LNG Procurement During the Hormuz Disruption. It develops a way to trace a buyer’s action through physical receiving constraints to the commercial alternatives available for an emergency purchase.

The distinction matters because a supplier list can give a false sense of resilience. Several firms may exist, several ships may be nearby, and several delivery dates may look plausible. The buyer still needs to know which options can work under the conditions the terminal actually faces.

Time has several meanings

Procurement involves several clocks. Suppliers need time to prepare bids. An offer remains valid for a specified period. A commercial commitment creates obligations. A vessel arrives, becomes ready and receives permission to discharge. Gas then enters storage while the terminal may continue sending gas into the network.

Calling all of this “lead time” can obscure the decision. A cargo may already be afloat when a buyer commits. An arrival date may precede the permitted unloading time. More time to submit a bid does not necessarily create another physically usable delivery opportunity. Each clock has to be connected to the event it measures.

The paper treats an operating action as a change to the path of usable stock and withdrawals. Its intended question is concrete: which cargo options become feasible after that change, and which suppliers can turn those options into acceptable offers?

Conservation changes the receiving problem

Reducing consumption preserves inventory. It can also preserve inventory that occupies the tank space needed for an incoming cargo. The same action may delay shortage while moving the window in which unloading is possible. A later opportunity may open while an earlier one closes.

The receiving model accounts for finite unloading time and simultaneous sendout. It follows stock at the start, at discharge commencement and at discharge completion. Under its specified piecewise-linear flows, these checkpoints establish whether the tank remains between its operational lower limit and capacity throughout unloading.

This gives the operational question a usable structure. Combine the receiving conditions with the allowed discharge-start calendar for each cargo. The result identifies the starting inventory levels at which that cargo can be received. Vessel waiting can be included through the calendar; gaps and isolated feasible times remain visible.

The model is a receiving benchmark. An operating recommendation also needs the costs of reducing demand, subsequent requirements, other receipts and any rebound in consumption. Those elements determine whether creating an option is worthwhile after its physical feasibility has been established.

Count alternatives at the same stock level

The central measurement problem appears when initial inventory is known only within a range. One supplier’s cargo may fit if stock is near the bottom of that range. Another may fit if stock is near the top. Counting both as possible can suggest a choice the buyer never actually has.

A simple synthetic example makes the issue visible. Suppose stock lies between zero and ten. One supplier is feasible between zero and four; another between six and ten. Both are individually possible, but there is no single stock level at which both are available as alternatives. A list of two possibilities has overstated the largest attainable choice.

The paper keeps the stock state common across suppliers. It combines each supplier’s cargo options, then counts the suppliers available at each admissible state. Checking the endpoints and the intervals between them yields the attainable counts, with witness stock levels showing where each count occurs. Multiple cargoes from one supplier remain one supplier choice.

The same discipline applies when comparing an operating action with the baseline. Both must begin from the same pre-action stock. Otherwise, an apparent improvement could be created by comparing favourable assumptions for the action with unfavourable assumptions for the baseline. Tracking supplier identities also reveals replacement that an unchanged headline count would conceal.

From feasible cargoes to participation

A physically admissible cargo still needs a supplier with the commercial right to sell or redirect it. The supplier must be qualified, invited and willing to bear the cost and exposure of making an offer. Geography, ownership of a parent company and an absent bid cannot establish those conditions by themselves.

The empirical design therefore reconstructs cargo opportunities independently of the bids received. It asks first whether a documented buyer action changes the feasible commercial options, then whether newly usable options lead to participation. Prices and eventual delivery are further outcomes in that sequence.

The current Pakistan LNG pilot contains three original evaluation reports covering four delivery windows and ten numeric quotes. These records provide a starting point for examining the procurement process. The next evidential step is to connect them to procurement-need identities, invitations, cargo rights, terminal stocks and documented operating actions.

Competition begins before the auction

The work currently establishes a conditional analytical method and an empirical research design. The pilot has yet to establish the action-to-options mechanism or a causal effect on participation, prices or savings. Its contribution is being developed at the junction where an operational possibility becomes a commercial choice.

That junction brings several disciplines into one decision. Engineering defines what can be received. Operations research maps feasible alternatives under shared constraints. Contract analysis identifies who controls the cargo and what delivery means. Procurement economics asks whether suppliers will enter, while empirical design determines which changes can be attributed to the buyer’s action.

For a buyer, the practical ambition is powerful: evaluate flexibility by the opportunities it creates, as well as the fuel it saves. A credible resilience strategy needs alternatives that can be used under the same real conditions. This research makes that requirement explicit enough to investigate, compare and test.
