Demurrage, done from documents
Laytime calculated from your documents, not by hand.
Upload the SOF, NOR and charter party or recap. Demca reads them, builds the timesheet and calculates demurrage or despatch. You check the lines, then export a finished document for your counterparty.
First calculation takes minutes. No card required.
Today it looks like this: a two-page SOF retyped into Excel line by line, every row checked against the exceptions list in the charter party, formulas rebuilt for each voyage. One wrong line is thousands of dollars in a claim — and it is the counterparty who notices.
How it works
Upload
You need SOF, NOR, charter party or fixture recap to upload in most popular formats (pdf, scans, photos or even emails are also fine).
Review
The extracted timesheet and calculation terms on one screen. Lines where extraction is unsure or the reading is arguable are flagged — you stay in control of every line.
Export
Excel with live formulas, or a PDF ready to send to the counterparty.
It pays for itself on the first voyage.
Hours → minutes
A manual calculation takes hours of a broker's time. A calculation in Demca takes minutes.
1 wrong line
A single missed or misclassified timesheet line is hundreds or thousands of dollars conceded in a claim.
Evidence
Every figure carries a reference to the document it came from — the claim can be defended line by line.
Why the numbers can be trusted
The calculation logic is coded from English case law on laytime and demurrage — not reinvented, but taken from the sources the industry actually relies on.
Every rule is covered by tests, and the calculation engine is separated from interpretation. A figure is reproducible and does not depend on how the question was phrased.
Every value in the calculation links to the exact place in the document it was taken from. You can defend the claim line by line.
Data & security
Your charters stay yours.
We built Demca assuming the first question you'll ask is where your documents live — here are the answers.
Encrypted everywhere
Data is encrypted in transit and at rest.
Record-level isolation
Your organisation sees only its own voyages. Source documents sit in private storage with individually granted access.
Never trained on
Client data is never used to train models. Never, under any conditions.
DPA on request
A data processing agreement is available — just ask.
