Settle Laytime and Demurrage Claims Faster With Fewer Disputes

Build laytime statements from clean evidence so demurrage claims are calculated once, agreed quickly and paid without months of back-and-forth.

In short
Most demurrage disputes come from evidence gaps: SOF conflicts, NOR questions and missing exceptions.
Lock the charter party laytime terms first, then reconcile all SOFs before calculating anything.
Submit complete claims with documents well inside the time bar, and track every claim to settlement.
The problem

A vessel waits five days at anchorage. The owner sends a demurrage claim. The charterer replies months later disputing the NOR tender time, rain stoppages and shifting time. The agent's statement of facts differs from the terminal's. Everyone digs through emails, and the claim sits unpaid while both sides argue about hours.

Laytime calculation is rarely the hard part. The hard part is agreeing which facts and which clauses apply. When the SOF, NOR, pumping logs and charter party exceptions are scattered, every claim gets built from scratch, errors creep in, and some claims miss the time bar entirely and are lost.

Why it happens
01Conflicting statements of facts from master, agent and terminal with no reconciliation
02Laytime, exceptions and NOR terms re-read from the charter party for every claim
03Supporting documents missing at submission, which invites rejection and delay
04No tracker for time bars, so claims are filed late or forgotten
How to fix it
1
Extract laytime terms once
For each fixture, record laytime allowed, commencement rules, NOR conditions, excepted periods, demurrage and despatch rates and the claim time bar in one structured summary.
2
Reconcile every statement of facts
Compare the master's, agent's and terminal's SOFs line by line. Resolve conflicting times with logs or emails before calculating, and record which source you accepted and why.
3
Calculate with every deduction shown
Build the laytime statement showing each event, exception applied and clause reference. A counterparty that can follow your logic has far less to dispute.
4
Submit complete, track to payment
Send the claim with charter party extracts, NOR, SOFs, logs and calculation together, well inside the time bar. Track status, queries and responses until settled.

Extracts laytime terms, flags SOF conflicts, drafts the laytime statement with clause references
Human gate
Demurrage analyst confirms disputed times and approves the claim before submission
Outcome
A documented claim filed on time and a tracker of every open claim
What to measure

Questions
What is the difference between laytime and demurrage?

Laytime is the time the charter party allows for loading or discharging without extra payment. Demurrage is the agreed amount the charterer pays the owner when that time is exceeded. Despatch, if agreed, is paid by the owner when cargo work finishes early.

Why do demurrage claims get rejected?

Common reasons are disputed NOR validity, conflicting statements of facts, exceptions not applied, missing supporting documents and claims submitted after the time bar. Most can be avoided by reconciling evidence before calculating and submitting a complete pack.

What is a demurrage time bar?

Many charter parties include a clause requiring demurrage claims, with specified supporting documents, to be submitted within a set period after discharge. If missed, the claim may be lost. Check the exact wording in each charter party, as terms vary.
