LNG scheduling & ADP software.
Same contract, different timing: millions in profit difference. Traders today pick the months by intuition.

PER CONTRACT YEAR, PURELY FROM WHERE THE DELIVERY WINDOWS LAND
The calendar decides profit or loss.
01 · THE PROBLEM
You sell four cargoes over six months and you choose the delivery months. That choice alone can swing $10M+ in profit, because the buy-sell spread shifts with seasons, demand and global events. And the schedule space is far too large to test by hand.
PRICES ARE UNCERTAIN: THE OPTIMAL SCHEDULE TODAY MAY NOT HOLD TOMORROW

02 · THE METHOD
Enumerate
All cargo-to-month combinations the contracts allow, SPA-compliant.
Subdivide
Start, mid and end of month: the pricing blend differs, and it is worth money.
Reprice
Monte Carlo across 1,000 price paths, against three or more sourcing markets.
Rank
By expected profit, computed in under 15 seconds. Fallbacks valued for every negotiation round.
Four cargoes to Japan: $100.2M, found in 13 seconds.
03 · THE RUN
A published example run: four cargoes delivered to Japan in the second half of 2026, priced across US, Qatari and European sourcing. The engine evaluated 3,060 schedules and returned the optimal programme in 13 seconds, with an average spread of +$7.37 per MMBtu.
VAR 5% OF THE OPTIMAL PROGRAMME: STILL PROFITABLE
04 · THE CLAIM
Spreadsheets can test 3 options.
X-ADP tests all 61,000 in seconds.
Six cargoes across twelve months with start, mid and end subdivisions create 61,000+ possible schedules, each priced against three or more sourcing markets under uncertain prices. Exhaustive enumeration with Monte Carlo repricing replaces intuition with a ranked list.
What the engine found in the Japan run.
05 · THE FINDINGS
Front-load to summer
JKM is highest in July and August; the spread compresses into winter.
Start-of-month wins
The pricing blend pulls in the higher prior-month forward, worth $2.2M extra across the programme.
US Gulf is the cheapest source
HH at $3.60 plus liquefaction and shipping lands at $9.60, against a JKM sale above $17.
A manual approach misses the timing value
Traders pick delivery months by intuition; the calendar effects above never surface in a three-option comparison.

Common questions.
08 · FAQ
- What is an annual delivery programme (ADP)?
- The yearly schedule of LNG delivery windows that buyer and seller agree under an SPA. Where those windows land decides a large share of the contract year’s value.
- How does ADP optimisation work?
- X-ADP enumerates every contractually feasible programme, reprices each with Monte Carlo across 1,000 price paths and ranks the list by expected profit. You negotiate from the top of the list, with fallbacks already valued.
- Why does the delivery month matter that much?
- The buy-sell spread moves with seasons, demand and global events. In the published Japan run, July-start earned +$8.11 per MMBtu against +$6.55 for October-start; the month choice alone can swing $10M+ per contract.
- What happens after the ADP is signed?
- X-LNG keeps the agreed programme optimal through the year: diversions, sub-lets, cancellation calls and slot changes are re-planned against it as the market moves.
