Your vessel has been at berth for two days longer than agreed. Your operations team knows. Your planning team knows. But by the time that information reaches finance, the window to act has already closed.
This is demurrage blindness. And it's costing the maritime sector more than most companies realise.
What demurrage actually costs
Demurrage rates vary by vessel type and trade lane, but daily rates of €5,000 to €25,000 are common in bulk and container shipping. A single undetected overrun of three days on one vessel can represent €75,000 in avoidable costs. Multiply that across a fleet, across a year, and the number stops being a line item and starts being a strategic problem.
Most companies don't track this accurately. Not because they don’t care, but because their systems weren't built to flag it in real time. The data exists somewhere. In a port agent report, in an email, in a spreadsheet someone updates twice a week. But by the time it's consolidated, reconciled and visible to the people who need to act on it, the laytime has already expired.
Three ways demurrage slips through
The first is late notification. Your port agent sends the Statement of Facts 48 hours after the vessel has departed. Your finance team receives it, processes it, and books the cost. Nobody questioned whether the calculation was correct, because nobody had the operational data to compare it against.
The second is uncontested claims. Demurrage claims from charterers or shipowners are often accepted without scrutiny, simply because the internal data to dispute them isn't readily available. Industry estimates suggest that a significant portion of demurrage claims contain errors or are based on disputed facts. But without real-time operational records, disputing them is nearly impossible.
The third is invisible accumulation. When demurrage isn't tracked per call, per vessel, per trade lane, it becomes invisible in your P&L. It sits inside broader cost categories, never surfacing as the pattern it actually is.
Real-time visibility changes the calculation
When your operational data flows directly into your financial system, demurrage exposure becomes visible the moment it starts building. Your planning team sees the overrun as it happens. Your finance team has the operational data to validate or
dispute every claim. And your management has a clear picture of demurrage as a cost driver, not as an occasional surprise.
That's not just better financial control. It's a fundamentally different way of managing risk in maritime operations.
At Ultimate Maritime Logistics, we've spent over 20 years building systems that bring operational and financial data together for exactly this reason. Demurrage doesn't have to be a cost you discover after the fact.
