The Notice of Readiness: The Most Disputed Document in Shipping

Every major demurrage dispute begins somewhere. In the vast majority of voyage charter party claims, the starting point is not the cargo, not the port, and not the rate. It is a single document that determines when the laytime clock begins to run. That document is the Notice of Readiness (NOR), and its deceptively simple function, notifying the charterer that the vessel has arrived and is ready to perform, generates more litigation in the English courts and before London arbitration tribunals than almost any other element of voyage chartering.

This post is a breakdown of what the NOR is, what makes it valid, what happens when it is not, and why getting it right matters enormously for both shipowners pursuing demurrage claims and charterers managing their liability exposure.

What the NOR Is and What It Does

A Notice of Readiness is the master's formal notification to the charterer or their agents that the vessel has arrived at the agreed destination and is ready in all respects, physically and legally, to load or discharge cargo. Its function under a voyage charter party is to serve as the trigger for the commencement of laytime. Until a valid NOR has been tendered, laytime does not run, and the owner cannot begin accumulating the right to claim demurrage if cargo operations overrun.

The NOR has two distinct purposes that sometimes pull in different directions. First, it starts the laytime clock. Second, it establishes whether the vessel has arrived within the agreed laycan, the window of time within which the vessel must be ready at the load port. Failure to tender a valid NOR within the laycan may give the charterer the right to cancel the charter entirely. These two purposes are governed by the same document, which means a defective NOR can simultaneously expose the owner to both a demurrage shortfall and a cancellation risk.

Under English law, there is no mandatory prescribed format for an NOR. A written statement from the master confirming that the vessel is ready to load or discharge is generally sufficient, provided it is factually accurate at the time it is given. However, charter party forms frequently impose specific requirements, regarding the method of delivery, the timing of tender, the office hours within which the NOR may be given, and the location from which it may be served. These requirements are strictly enforced, and deviations from them can invalidate the notice entirely.

The Three Requirements for a Valid NOR

For a NOR to be valid under English law, three conditions must be satisfied at the time the notice is tendered:

The vessel must be an "arrived ship." The vessel must have reached the agreed destination as defined by the charter party, whether that is a named port, a berth, a dock, or a specific anchorage. This distinction matters significantly. In a port charter, the vessel need only arrive within the port limits to tender a valid NOR. In a berth charter, the vessel must be at the specific berth before NOR can be given. Whether a vessel qualifies as an arrived ship is determined by the three-part test established by the House of Lords in The Johanna Oldendorff (Oldendorff (EL) & Co GmbH v Tradax Export SA [1973] 2 Lloyd's Rep. 285): the vessel must be within the port area, it must be at the immediate and effective disposition of the charterer, and it must be waiting at a location that is the usual waiting place for vessels of that type.

The vessel must be physically ready. The cargo holds, pumps, cranes, and all equipment required for cargo operations must be ready to perform at the moment the NOR is tendered, not at some anticipated future point. The vessel must be prepared to obey the charterer's loading or discharging instructions whenever those instructions are given. In The Tres Flores (Compania de Naviera Nedelka SA v Tradax International SA [1973] 2 Lloyd's Rep. 247), the Court of Appeal held that an NOR tendered while pests were present in the vessel's cargo holds was invalid. The holds required fumigation before the vessel could receive the chartered cargo, and Lord Denning confirmed that both as a matter of contract construction and at common law, the vessel was required to be ready to load before a valid NOR could be given. The charterer's willingness to treat completion of cleaning as the commencement of laytime did not rescue the owner's position. The first NOR was null.

The vessel must be legally ready. This means all regulatory, customs, immigration, and health clearances necessary to commence cargo operations must be in place. Free pratique, the authorization to conduct normal intercourse with the shore, is the most commonly encountered requirement. Some charter parties permit NOR to be tendered before free pratique is granted, with specific wording to that effect. Without such a clause, an NOR tendered before free pratique has been granted may be invalid on legal readiness grounds.

What Happens When an NOR Is Invalid

The consequences of tendering an invalid NOR are severe and, under English law, largely unforgiving. An invalid NOR does not start laytime. Laytime will not commence until a valid NOR is tendered and the other charter party conditions for commencement are met. This means that every hour between the invalid tender and the valid re-tender is time the owner has lost, or in other words, time that cannot be recovered by arguing that the charterer knew or should have known the vessel was ready.

The Court of Appeal addressed this directly in The Happy Day (Glencore Grain Ltd v Flacker Shipping Ltd [2002] 2 Lloyd's Rep. 487). The vessel was chartered to carry wheat from Odessa to Cochin. The master tendered an NOR that was subsequently found to be invalid. The Court of Appeal confirmed that the invalid notice was a nullity when given and ineffective to commence laytime, even if the charterers knew or ought to have known of the vessel's subsequent readiness. An owner who tenders an invalid NOR cannot rely on the charterer's commercial awareness of the vessel's condition as a substitute for procedural compliance. The owner must tender a further, valid NOR, and laytime runs only from that point.

The Happy Day also addressed the doctrine of waiver in this context, which is the most significant exception to the harsh consequences of an invalid NOR. The court held that a charterer can waive the invalidity of an NOR, but the circumstances in which this occurs are narrowly defined. In The Happy Day itself, the court found that although the NOR was invalid, the charterers had accepted it through their agents upon commencement of discharge, and laytime commenced at that point. However, the court was clear that such an acceptance, in circumstances where the charterers were unaware of the inaccuracy in the NOR, could not bind the charterers. They would not be prevented from later disputing the effect of the notice. Waiver requires actual knowledge of the defect and a clear election not to exercise the right to a valid notice. Silence in response to an NOR, or commercial engagement with cargo operations, is not automatically sufficient to constitute a waiver.

Method of Tender and Charter Party Formalities

Beyond the substantive requirements of arrival and readiness, the procedural requirements for tendering an NOR are a frequent source of dispute in their own right. Charter party forms commonly specify the methods by which an NOR may be delivered, letter, fax, telex, or telephone.

In a case involving an amended BPVoy3 form, the Commercial Court was asked to consider whether an NOR tendered by email constituted a valid notice. Clause 19 of BPVoy3 specified delivery methods including letter, facsimile, telegram, telex, radio, or telephone. The court held that email was not a valid method of tendering NOR under that clause, as only the methods expressly listed in the charter party were permissible. This is a striking illustration of how literally English courts read the procedural requirements of charter party clauses, particularly where significant financial consequences attach to compliance.

The timing of NOR tender within specified office hours is another area of dispute. Where charter parties require NOR to be tendered during normal local office hours, a notice served outside those hours may not be effective to commence laytime until the next working period, even if the vessel is fully arrived and ready. The financial consequence of a notice served at 6pm on a Friday under a clause specifying office hours of 08:00-17:00 Monday to Friday can be substantial, potentially meaning the laytime clock does not start until Monday morning.

WIBON, WIPON and the Risk of Port Congestion

In the current disrupted shipping environment, where port congestion is a major operational reality for vessels trading anywhere near the Arabian Gulf or using alternative routing via the Cape, the allocation of congestion risk in the NOR framework is particularly relevant.

In a berth charter party, a vessel that has arrived at the port but cannot proceed directly to the berth due to congestion is generally not yet an "arrived ship" in the legal sense, meaning no valid NOR can be tendered until the berth is available, and laytime does not run during the waiting period. This is commercially significant for owners, as the time spent at anchor waiting for a berth is entirely at the owner's risk and cost unless the charter party modifies the default position.

Two standard clauses address this directly. WIBON (whether in berth or not) permits the owner to tender NOR and commence laytime even when the vessel has not yet reached the designated berth, provided that the reason for the delay is port congestion. WIPON (whether in port or not) goes further, permitting NOR to be tendered from the usual anchorage outside port limits entirely. These clauses transfer the congestion risk to the charterer and are among the most commercially significant clauses in any voyage charter party. Owners trading in congested ports who do not have WIBON or WIPON protection may find themselves absorbing significant waiting time that they assumed would count toward their demurrage entitlement.

A related clause, "reachable on arrival" or "always accessible," goes even further than WIBON or WIPON by requiring the charterer to warrant that the vessel will be able to proceed directly to the berth upon arrival. If the berth is not accessible for any reason, including congestion or weather, the owner may be entitled to damages for detention, and laytime will run from the vessel's arrival. In a market where Jebel Ali is congested, where alternative Gulf ports are operating under drone attack risk, and where vessels are waiting at anchorage for extended periods, the presence or absence of these clauses in the charter party is the difference between a recoverable claim and an unrecoverable loss.

The Practical Discipline Required

For masters and owners, the NOR is not an administrative formality. It is a legal document that must be factually accurate at the moment of tender, compliant with the specific requirements of the charter party form in use, delivered by a permitted method, and tendered at the right location. If there is any doubt about whether the vessel is fully ready, physically or legally, do not tender the NOR. A premature NOR is a nullity, and you will need to tender again once readiness is actually achieved. The golden rule in practice is to tender NOR promptly on genuine arrival and readiness, and to re-tender without delay if circumstances change or if the first tender is called into question.

For charterers, an invalid NOR is a legitimate and powerful defense to a demurrage claim. If a vessel tendered NOR at the wrong location, outside permitted office hours, by an impermissible method, or before it was physically or legally ready, that notice is a nullity. Be alert to these deficiencies, particularly in ports where free pratique delays are common or where congestion means vessels are tendering NOR from anchorage under berth charter terms. However, be equally aware that commencing cargo operations without raising the invalidity of the NOR may constitute a waiver of the defect, and that waiver is difficult to claw back once operations are underway.

For cargo interests and freight forwarders, the NOR is the document that determines when your counterparty's demurrage clock started running. If demurrage is being claimed against you under a bill of lading that incorporates the charter party terms, understanding whether a valid NOR was tendered, and when, is the first question to ask. Defects in the NOR that were not raised at the time are not always fatal to a later challenge, but the further removed from the event, the harder the argument becomes.

The NOR is a small document with large consequences. Getting it right is not complex. It requires attention to the charter party, awareness of the vessel's actual condition, and procedural discipline. Getting it wrong, even for the most procedurally straightforward reasons, can be the difference between a successful demurrage claim and a complete bar to recovery.
