OPTI-TANKER · Tanker Scheduling Optimizer
OPTI-TANKERis a tanker scheduling optimizer — it builds and replans 90-day voyage schedules for oil & gas majors and cargo owners.
OptiTanker replans through every disruption — where most of the cost saving actually lands.
Built for the people who own the cargo, not the ships that move it.
Why this is universal
What this means for your P&L
Tanker classes OptiTanker schedules
Each class brings its own draft, LOA and beam constraints — and its own match with the load and discharge ports it can reach. OptiTanker honours all of them before it ranks a single voyage.

Outcome figures: Solverminds internal product review, 2026-05-28.
The "multiple" conundrum, solved
Five vessels. Five grades. Eight load and discharge ports. Eight weeks. Every grade-to-grade transition flagged for tank cleaning. Every voyage costed and ranked. Generated in under 10 minutes.

What's inside
OptiTanker replans through every disruption — where most of the cost saving actually lands.
Built for the people who own the cargo, not the ships that move it. Oil & gas majors, commodity traders and cargo owners run 90-day tanker plans across multi-grade cargo, multiple load and discharge ports, and tens of millions in TC commitments. OptiTanker collapses the planning cycle to minutes — and per the published white paper, the majority of cost saving accrues not from the first plan, but from the rebuilds after every disruption.

VLCCs in service
Very Large Crude Carriers — the workhorses of long-haul oil shipping, each carrying up to 320,000 DWT.
~60%
Of world oil moves by tanker
The other 40% moves by pipeline. Every barrel that ships hits a tanker schedule and a port-pair cost equation.
What this means for your P&L
Every chartered day on a profitable voyage. Spot tonnage only when TC fleet is genuinely maxed out.
Demand forecasts at every discharge port. Stock stays above safety, contracts stay intact, customers stay yours.
Incompatible grade transitions auto-flagged and cleaned. Multi-million-dollar cargo claims, prevented.
Every candidate voyage ranked by cost-per-ton-mile. The cheapest valid assignment, every single time.

Verified deployment · global oil major
A global oil major deployed OptiTanker on its tanker scheduling operation. Anonymized at the customer's request. Below are the verified results — and the saving compounds with fleet size.
Outcome figures: Solverminds internal product review, 2026-05-28.
The majority of the cost saving accrues not from the first plan, but from the rebuilds after every disruption — congestion, vessel breakdown, weather, blocked canals. OptiTanker replans in minutes, and the savings stack up over every month of the year.
Your TC fleet · today
OptiTanker maximizes charter utilization across your fleet. The only "idle" you'll see is necessary tank cleaning between incompatible grades — auto-scheduled, never wasted.
