You Accepted the Vessel's NOR. You Accepted the Start of Laytime.
Quote from chief_editor on June 11, 2026, 5:30 pmAccepting a vessel's Notice of Readiness starts the laytime clock. Port agents who accept NOR without charterer authorization can create demurrage liability the charterer did not intend.
A grain trader who had chartered a Handymax for loading wheat from Novorossiysk received a claim for $47,000 in demurrage three weeks after the voyage completed. The claim was based on the laytime calculation starting from NOR acceptance — which, according to the shipowner's calculation, occurred at 09:00 on a Monday morning. The trader believed NOR had been accepted on Tuesday afternoon, which would have produced a laytime calculation showing dispatch rather than demurrage.
Investigating the discrepancy, the trader found that their port agent in Novorossiysk had sent an acknowledgment of the NOR to the vessel's master at 09:00 Monday. The port agent had not checked with the trader before doing this. The agent's practice was to acknowledge NOR upon receipt as a matter of routine, without distinguishing between commercial acceptance of laytime and administrative confirmation of receipt.
The two actions — acknowledging receipt of the NOR as a communication and accepting the NOR as the triggering event for laytime — are different commercial and legal acts. The port agent had conflated them. The difference in this case: 30 hours of laytime, at $1,567 per day: $1,958. The total demurrage claim was $47,000 because subsequent delays compounded onto the earlier start.
NOR Acceptance Is a Legal Act With Commercial Consequences
A Notice of Readiness is the formal communication by which a vessel's master declares that the vessel is ready in all respects to load or discharge cargo. The moment the NOR is validly accepted — by the charterer, their agent, or the terminal — laytime begins counting. Every hour from that moment counts against the laytime allowance.
Accepting a NOR requires: verifying that the vessel is actually at the location required under the charterparty (within port limits for WIBON clauses, at the berth for berth charterparties), verifying that the vessel is actually ready to load or discharge (holds cleaned, holds inspected and approved if required), and — crucially — verifying that commercial acceptance is appropriate at that time.
A port agent who routinely acknowledges NOR without checking any of these conditions is creating laytime liability that the charterer has not authorized. The agent's acknowledgment, sent to the vessel's master, may be treated by the shipowner as the NOR acceptance that starts laytime. Whether this characterization is legally correct depends on the charterparty terms and the applicable law, but defending the characterization in arbitration costs money and takes time.
The practical instruction that port agents at major commodity export and import terminals need to receive from the charterer: do not acknowledge or accept NOR without explicit authorization from the charterer for each vessel and each voyage. This instruction needs to be part of the port agency mandate for every voyage where laytime management matters — which is every voyage where the cargo volume, vessel size, and port conditions create meaningful demurrage exposure.
The Time Zone Problem in NOR Management
For commodity traders managing voyages across multiple time zones, the NOR timing question involves an additional complication: the vessel's master may tender NOR at a time when the trader's office is closed and the port agent is the only available point of contact. In the early hours of a London morning, when a vessel arrives at a Pacific port and the master tenders NOR, the London trader is asleep. The port agent, operating local business hours, is the only active commercial presence.
Port agent mandates that specifically address NOR handling in out-of-hours situations — specifying what the agent can do autonomously, what requires the charterer's authorization regardless of time, and how to contact the charterer in urgent situations — prevent the Monday morning acknowledgment problem. Agents who have clear instructions behave consistently. Agents who have no instructions about NOR handling will do what seems administratively reasonable, which may not be commercially appropriate.
