Private charter party intelligence.

CharterWise reads the agreement and works the voyage on the same machine. The aim is simple: show the owner what can move TCE, the charterer what can move landed freight, and both sides which clause created the exposure.

The contract is the operating model.

Cargo intake, vessel readiness, bunkers, canal costs, port restrictions, sanctions and payment terms can move a voyage before laytime begins. Yet the wording and the workings are still reviewed apart.

They belong in one chain: clause, trigger, evidence, probability or quantity, financial effect, risk bearer, action and deadline. The agreement stays on your hardware; an external lookup receives only the minimum field it needs.

How the boundary works

Seven moving parts

Bring the voyage into line.

Work the variables together. See what moves owner TCE, charterer landed freight and the risk between them.

Seven voyage variables move from independent orbits into one working line, which becomes a key and opens the fixture.

From clause to voyage result.

ReadingThe form, the amendments and every rider resolved into one usable record.OpenClose

Start with the document as it is: PDF, scan or photograph. CharterWise reads it page by page and identifies the form.

Printed clauses, struck amendments and riders stay in context, including the clause each rider overrides.

A scanned line becomes a usable term without the document leaving the machine.
ExposureWhat changed, who carries it and why it matters.OpenClose

The agreement is checked against the clause schedule for its form. Missing wording and deviations are surfaced with severity and plain-English reasoning. Rider overrides remain connected to the printed clauses they change.

Each material finding should answer four questions: what triggers it, what evidence can measure it, who bears it and what it may do to the voyage.

Part II · Printed terms

Clause 1. Cargo quantity

Charterers shall load a full and complete cargo of one hundred and seventy thousand one hundred and sixty-five thousand metric tons, five per cent more or less in Owners’ option, subject to the Vessel’s safe sailing draught.

Rider · Clause 29

Notwithstanding Clause 1, quantity shall be limited by the maximum permissible sailing draught at the loading port. Any shortfall caused by that limit shall not count as deadfreight.

The economics often sit in the alteration or rider, not the printed form.
ComparisonTwo fixtures, compared on wording and economic effect.OpenClose

Compare two agreements clause by clause and isolate what is identical, what moved and what disappeared.

A useful comparison goes beyond a redline. It asks what the changed wording does to the economics and which side of the fixture moved.

At USD 10.50 per tonne, the 5,000-tonne difference moves gross freight by USD 52,500 before any deadfreight claim.
One wording change; equal and opposite exposure for owner and charterer.
Voyage workingsThe contract terms and operating assumptions in the same calculation.OpenClose

Freight, cargo quantity, bunkers, port costs, commissions and time sit in an editable voyage working that recalculates as the assumptions move.

That working should not stop at one number. It should show the downside around owner TCE and charterer landed freight, with every assumption open to challenge.

For investors

The agreement starts to calculate.

Chartering desks work with three separate objects: the signed wording, a voyage estimate and the evidence outside both. CharterWise joins them. A clause is linked to its trigger, the evidence that can test it, the party carrying the exposure, the financial effect and the action due.

CharterWise can read a scan or PDF, keep riders beside the printed terms they alter, compare agreements and recalculate the voyage as assumptions change. Contract text stays on customer hardware. Document review and voyage calculation become one workflow.

Owner outcome

Tighter TCE.

Earlier visibility of freight at risk and fewer voyage days left unpriced.

Charterer outcome

Tighter landed freight.

Earlier visibility of payable exposure and fewer costs discovered after fixing.

No blanket savings percentage belongs here until live voyages supply the evidence. The performance test is simple: compare forecast and actual owner TCE, compare forecast and actual charterer landed freight, and count the dollar value of material exposure found before signing.

Faster document review saves time. The larger opportunity is decision control: a clause can change the working before the fixture is signed, and every forecast can be checked against the voyage that followed. If CharterWise narrows that gap, the value appears directly in dollars per day and dollars per tonne.
