Calculation of Demurrage
How are Demurrage Charges calculated?
In the calculation of demurrage amount payable to shipowner, demurrage rate is multiplied by the number of days or part of day in excess of the agreed laytime. For example:
- Total Laytime Allowed 11 days
- Demurrage Rate $60,000 per day pro rata (PDPR)
- Ship exceeded laytime allowed for loading and discharging by 4 days 6 hours 30 mins
- Demurrage Payable =4d 6h 30m x $60,000 per day =4.27083 days x $60,000 = $256,250
In order to arrive at the number of days on demurrage, a calculation of the time in port must be made making reference to the time allowed (laytime) and whether time is counting or whether it is an exception and does not count. Demurrage calculation is similar to using a stopwatch in that the clock will continue to run until there is a qualifying exception and the time will stop. Therefore, in any charter-party it is important to know exactly when the agreed laytime has expired as the ship, from that point, ship will be on demurrage.
‘Once on Demurrage, Always on Demurrage’ phrase is sometimes overused and often misleading. It is crucial to note that the rules for the stopwatch change when a ship is on demurrage and careful attention must be paid to the detail of the specific charter-party when this happens.
General rule is that express exceptions to laytime do not apply to demurrage unless there is clear wording in the charter-party to that effect. Theoretically, the clock does not stop running once the ship has gone on demurrage,
For example, Asbatankvoy – Clause 7 last sentence reads as follows: Time consumed by the ship in moving from loading or discharge port anchorage to her loading or discharge berth, discharging ballast water or slops, will not count as used lay time. If the ship was moving from the anchorage to the berth and the laytime at that time had not been used up then time will not run during the period of moving to the berth. On the other hand, if lay time had expired and the ship was on demurrage then time would continue to run for such an event and the owner is entitled to demurrage for this time.
Great care must be taken over the wording of the charter-party for events which interrupt laytime to apply to demurrage.
Demurrage would not run where there is a fault on the part of the shipowner. For example, a ship breakdown, as shipowner should not be able to profit (paid for demurrage) for his own breach of contract. General exceptions clauses will not apply to demurrage unless the wording specifically supports this. Time on demurrage ends at the same time as laytime would have done, such as when completion of cargo operations in dry bulk market or when disconnection of cargo hoses in the tanker market.
When is Demurrage Payable?
Gencon Charterpary (GENCON 94) Clause 7 states ‘Demurrage shall fall due day by day and shall be payable upon receipt of the owners’ invoice.’ In this case an owner is entitled to submit an invoice every day for as long as the vessel is on demurrage. Clearly where there are long delays and large amounts of demurrage incurred the owner may want to do so to ensure that the charterer becomes liable immediately.
In practice a claim is submitted at the end of the voyage and, after a period of negotiating the details and amount, agreement is reached and one payment made for the entire claim. Absent the Gencon wording, it is generally accepted that demurrage is payable day by day. However some charterparties will include express terms about the timing of payment which will need to be examined on a case-by-case basis.
What is Demurrage?
Demurrage refers to the liquidated damages payable by the charterers to the shipowner for failing to complete the loading or discharging of the ship within the agreed laytime period.
Demurrage is not payable when the charter party expressly provides that certain periods of time lost, such as breakdown or inefficiency of the ship, shall not count for demurrage, However, the general rule is “once on demurrage, always on demurrage” i.e., if a ship is on demurrage, no laytime exceptions such as Sundays and holidays can be deducted from the computation of demurrage.

Demurrage Rate
Demurrage is the name given to the damages payable by the Charterer to the Shipowner for the Charterer’s Breach of Charterparty in delaying the ship beyond the agreed laytime. Demurrage is Liquidated Damages that means the rate per day is fixed at the time the charterparty is agreed. Furthermore, Shipowners (Disponent Owners) and Charterters know in advance their respective liabilities/earnings in the event of a delay. This is distinct from Damages at Large which would require a Shipowner to prove his losses. For demurrage, the Shipowner only has to prove that the delay falls within the terms of demurrage for the relevant charterparty. The Demurrage Rate agreed is much like the Freight Rate, Demurrage Rate will be a reflection of the running costs of the ship and the market conditions. Usually, the Demurrage Rate is agreed in the charterparty as a Daily Rate. For part of a day, the rate is pro rated as.
Once on Demurrage, Always on Demurrage
If a charterer keeps the vessel beyond the agreed lay days, this constitutes a breach of contract. Most charterparties include a clause that allows the charterer to retain the vessel for additional days to complete loading or discharging, upon payment of a predetermined daily fee called demurrage.
Historically, this extra period was referred to in court as “lay days that have to be paid for.” This term can be misleading because it obscures the fact that the charterer is actually breaching the contract, even though they can mitigate further damage by completing their contractual obligations during this period upon paying the agreed rate.
This creates an unusual situation where, despite the breach, the shipowner cannot cancel the contract and reclaim the vessel during the demurrage period unless the charterer’s failure to load is so severe that it amounts to a contract repudiation, or the delay fundamentally undermines the purpose of the charterparty. This is the case whether the charter specifies a fixed number of demurrage days or not, as in “eight days for loading, after which demurrage at $10,000 per day.”
Legally, a demurrage clause is a contract-specific creation that acts as an agreed compensation for detaining the vessel beyond the lay days. The predetermined sum is collectible by the shipowner without needing to demonstrate actual damage, and it caps the compensation for losses due to the detention.
Demurrage covers potential losses from delayed subsequent charters or from fewer voyages possible under a consecutive voyage charter-party. However, it does not limit compensation for other types of losses, such as those resulting from not loading a full cargo.
Courts can invalidate a demurrage clause if the set rate is exorbitantly high compared to the maximum conceivable loss from the breach, viewing it as a penalty rather than a fair compensation. Conversely, if the rate is unreasonably low, the shipowner cannot claim beyond this rate even if the actual losses are greater, potentially due to deliberate delays by the charterer. This can be particularly problematic when market conditions are changing rapidly, leaving the shipowner without sufficient recourse in cases of severe delay.
The demurrage rate is typically aligned with current freight rates at the time the charter is finalized. Since charters are often arranged well in advance, the demurrage rate might not reflect market rates at the time it is invoked.
The obligation to pay demurrage begins immediately after lay days end and continues non-stop, including over weekends, holidays, and other times usually excluded from laytime, such as bad weather days.
The principle “once on demurrage, always on demurrage” applies, meaning laytime exceptions generally do not affect demurrage periods unless explicitly stated otherwise. For instance, the House of Lords once ruled that a charterer could not use a strike as an excuse after laytime ended, reasoning that had the contract been fulfilled on time, the strike would not have impacted the vessel since it would have been at sea.
This rule can still apply even if the excepted event occurs before laytime ends. An exception might be explicitly stated to cover the demurrage period, for example, stipulating that demurrage is payable “at 12s 6d per hour unless detention arises from a lock-out, strikes etc.” Moreover, demurrage does not accrue during delays caused by the shipowner or actions taken for the shipowner’s benefit. However, it does accrue for accidental delays not attributable to either party. If a delay results from the shipowner’s breach of contract, demurrage may still be due if the delay’s extent was beyond what the parties reasonably anticipated as a consequence of the breach.
Demurrage as Liquidated Damages
It should be remembered that since demurrage represents the amounts which the Shipowners (Disponent Owners) and Charterers have agreed are payable by the Charterer to the Shipowner to recompense it for any losses which it has suffered as a result of the detention of the ship beyond laytime, it follows that the Shipowner may not be able to recover other losses which it has suffered as a result. These Liquidated Damages (Demurrage) represent all the damages which can be recovered by the Shipowner where the laytime is exceeded. Therefore, the Shipowner (Disponent Owner) may not be able to recover extra bunkers or port costs incurred by it as a result of the delay or even the loss of a valuable next cargo (fixture) which is cancelled as a result of the delay.
To recover other losses, the Shipowner must show that the charterer is also in breach of another provision of the charterparty. For example, in a case called Reider v Arcos (1926) Case, the Shipowner proved that, as a result of the charterer’s delay, the ship could not leave port with a full cargo because the depth of water over the bar had dropped. The charterer therefore loaded less cargo than it would have loaded if there had been no delay and the owner recovered deadfreight for the Charterer’s breach on top of demurrage.
Ship Detention
Laytime is entirely at the charterer’s disposal, as it is considered compensated within the freight cost. The charterer has the right to use the laytime as deemed fit, without the shipowner being able to object, provided the specified period is not exceeded. The method and pace of loading and discharging are solely for the charterers to determine, irrespective of whether the process is intermittently slow or swift.
The principles of laytime were notably applied in the case of Margaronis Navigation Agency v Peabody. Here, a vessel was chartered to load maize at a rate of 1,000 tons per weather working day, excluding Sundays and holidays. The charterers, having loaded all but 11 tons by late December, halted the operations to secure January bills of lading, resuming only on the next working day of the new year to complete the loading within 40 minutes. Despite finishing within the agreed laytime, the shipowners sought damages for detention, alleging that the charterers detained the vessel unnecessarily. However, the Court of Appeal supported the arbitrator’s decision that the charterers were justified in detaining the vessel until all the contracted cargo was loaded, given the trivial shortage of approximately 12 tons.
Contrastingly, the charterer cannot detain the vessel once the loading is complete, even if laytime remains. In the case of Nolisement (Owners) v Bunge y Born, the loading concluded 19 days before the lay days expired, but the charterers delayed for three days due to indecision about the discharge port, leading to a liability for two days’ detention. This highlights a potential inconsistency, as charterers could avoid such penalties by simply retaining a minimal amount of cargo.
It’s important to note that the loading phase isn’t considered complete until the cargo is both aboard and stowed. Although stowage is typically the shipowner’s responsibility and cost, it remains part of the loading process, and the charterer must ensure the cargo is delivered timely for stowage within the lay days.
With the end of the loading operation, the second phase of the voyage charter-party concludes, and any subsequent delays from unforeseen obstacles, such as ice or bad weather, fall back to the shipowner’s responsibility, meaning the shipowner bears the costs associated with such delays.
Damages for Ship Detention
When a charterparty lacks a specific provision for demurrage, a charterer becomes liable for damages due to detention for any period the vessel is retained beyond the agreed lay days. In such cases, damages are considered “at large” and are assessed by the court based on the actual loss incurred by the shipowner, following standard principles regarding the remoteness of damage in contract law.
Damages for detention are also deemed the appropriate form of compensation when a charter-party specifies a fixed number of days for demurrage, and those days have elapsed. Typically, courts will calculate damages based on the previously agreed demurrage rate. However, it remains open for either party to demonstrate that this rate does not accurately reflect the shipowner’s actual losses.
During any agreed demurrage period, a shipowner is not permitted to withdraw the vessel, unless the delay frustrates the purpose of the charterparty. Conversely, once the specified demurrage period ends, the shipowner is not obligated to stay at the port to finish loading. At this point, the shipowner may depart and is only entitled to claim damages for detention.
If only part of the cargo has been loaded when demurrage expires, the shipowner may choose to depart and seek compensation for dead freight. Conversely, if the charterer fails to load any cargo, the shipowner has the right to terminate the charter and sue for extensive damages. However, if the delay occurs at the discharging port, the shipowner’s options are limited to completing the unloading process and then claiming damages for detention.

Ship Detention in Dry Bulk Shipping
Damages for ship detention refer to the financial compensation sought by a ship owner or charterer when a vessel is unduly delayed or detained by a third party, such as a port authority, shipper, or consignee. These damages are meant to cover the losses incurred as a result of the vessel being unavailable for other potential charters, increased operational expenses, or other associated costs.
In the event of ship detention, the following steps can be taken to recover damages:
- Identify the cause of detention: Determine the reason for the delay or detention, such as port congestion, labor strikes, customs issues, or delays in cargo handling. Establish whether the detention was caused by a breach of contract, negligence, or another actionable reason.
- Document the detention: Keep a detailed record of the events, including the timeline of events, correspondence with the parties involved, and any other relevant documentation. This information will be crucial in supporting a claim for damages.
- Calculate damages: Determine the amount of damages incurred as a result of the detention. This may include the loss of income from potential charters, additional operational expenses, crew wages, and other associated costs. The calculation should be based on the daily rate specified in the charter party agreement or, in the absence of such an agreement, a reasonable market rate.
- Notify the responsible party: Once the cause of detention and the damages have been identified, inform the responsible party of the situation and provide them with an opportunity to rectify the issue. Keep a record of this communication for future reference.
- Pursue legal action: If the detention is not resolved and the responsible party is unwilling to compensate for the damages, consider seeking legal advice and pursuing a claim in court or through arbitration. Provide all relevant documentation and evidence to support your claim.
- Mitigate damages: While pursuing damages, take steps to mitigate the impact of the detention. This may involve seeking alternative charters, reducing operational costs, or resolving the issue that caused the detention.
Damages for ship detention are meant to compensate the ship owner or charterer for losses incurred due to delays or detention caused by third parties. To recover these damages, it is essential to identify the cause of detention, document the events, calculate the damages, notify the responsible party, and pursue legal action if necessary. Additionally, taking steps to mitigate damages can help reduce the overall impact of the detention.
How is Demurrage Calculated?
Demurrage is a fee charged to the charterer by the shipowner for not loading or unloading the cargo within the agreed-upon laytime. Laytime is the time allocated for these processes, usually specified in the charter party (contract between the shipowner and charterer). Demurrage calculations can vary depending on the specific terms of the contract, but the general process involves the following steps:
- Determine the Laytime: Laytime is usually stated in hours or days in the charter party. It is the period during which the ship must be loaded and unloaded without incurring demurrage charges.
- Calculate Used Laytime: Calculate the actual time taken for loading and/or unloading. This may include weekends, holidays, and other exceptions as specified in the contract.
- Identify Any Exceptions: Identify any time periods excluded from the laytime calculation as per the contract terms, such as bad weather, customs delays, or equipment breakdowns. Subtract these periods from the used laytime to arrive at the adjusted laytime.
- Compare Laytime and Adjusted Laytime: If the adjusted laytime is less than or equal to the agreed-upon laytime, there is no demurrage. If the adjusted laytime exceeds the agreed-upon laytime, demurrage is incurred.
- Calculate Demurrage: To calculate demurrage, first determine the excess time by subtracting the agreed-upon laytime from the adjusted laytime. Then, multiply the excess time by the demurrage rate specified in the charter party. The demurrage rate is usually quoted in USD per day or per hour.
Demurrage Calculation Example 1
- Agreed laytime: 5 days
- Actual laytime used: 7 days
- Weather-related delays: 1 day
- Demurrage rate: $15,000 per day
Adjusted laytime = Actual laytime used – Weather-related delays = 7 days – 1 day = 6 days
Since the adjusted laytime (6 days) is greater than the agreed laytime (5 days), demurrage is incurred.
Excess time = Adjusted laytime – Agreed laytime = 6 days – 5 days = 1 day
Demurrage = Excess time × Demurrage rate = 1 day × $13,000 per day = $13,000
In this example, the charterer would be required to pay $13,000 in demurrage charges to the shipowner.
Demurrage Calculation Example 2
Here is another example of Demurrage Calculation:
Assumptions:
- Agreed laytime: 10 days
- Actual laytime used: 14 days
- Non-working days (e.g., weekends, holidays): 2 days
- Customs-related delays: 1 day
- Demurrage rate: $15,000 per day
Step 1: Calculate the adjusted laytime Adjusted laytime = Actual laytime used – Non-working days – Customs-related delays = 14 days – 2 days – 1 day = 11 days
Step 2: Compare laytime and adjusted laytime In this case, the adjusted laytime (11 days) is greater than the agreed laytime (10 days), which means demurrage is incurred.
Step 3: Calculate demurrage Excess time = Adjusted laytime – Agreed laytime = 11 days – 10 days = 1 day
Demurrage = Excess time × Demurrage rate = 1 day × $15,000 per day = $15,000
In this example, the charterer would be required to pay $15,000 in demurrage charges to the shipowner.
Demurrage Calculation Example 3
Here’s another example of demurrage calculation:
Assumptions:
- Agreed laytime: 8 days
- Actual laytime used: 12 days
- Non-working days (e.g., weekends, holidays): 3 days
- Mechanical breakdown delays: 1 day
- Demurrage rate: $12,000 per day
Step 1: Calculate the adjusted laytime Adjusted laytime = Actual laytime used – Non-working days – Mechanical breakdown delays = 12 days – 3 days – 1 day = 8 days
Step 2: Compare laytime and adjusted laytime In this case, the adjusted laytime (8 days) is equal to the agreed laytime (8 days), which means no demurrage is incurred.
Step 3: Calculate demurrage Since the adjusted laytime does not exceed the agreed laytime, there is no excess time, and therefore, no demurrage charges are applied.
In this example, the charterer would not be required to pay any demurrage charges to the shipowner.
Demurrage Calculation Example 4
Here’s another example of demurrage calculation:
Assumptions:
- Agreed laytime: 6 days
- Actual laytime used: 9 days
- Non-working days (e.g., weekends, holidays): 2 days
- Weather-related delays: 1 day
- Demurrage rate: $8,000 per day
Step 1: Calculate the adjusted laytime Adjusted laytime = Actual laytime used – Non-working days – Weather-related delays = 9 days – 2 days – 1 day = 6 days
Step 2: Compare laytime and adjusted laytime In this case, the adjusted laytime (6 days) is equal to the agreed laytime (6 days), which means no demurrage is incurred.
Step 3: Calculate demurrage Since the adjusted laytime does not exceed the agreed laytime, there is no excess time, and therefore, no demurrage charges are applied.
In this example, the charterer would not be required to pay any demurrage charges to the shipowner.
Demurrage Calculation Example 5
Here’s an example of a demurrage calculation:
Ship details:
- Name: MV Handybulk Oceanic
- Demurrage rate: $10,000 per day (pro-rated)
- Allowed laytime: 5 days
- Actual laytime used: 7 days
In this example, we will calculate the demurrage for MV Handybulk Oceanic.
Step 1: Calculate the excess laytime Excess laytime = Actual laytime used – Allowed laytime Excess laytime = 7 days – 5 days Excess laytime = 2 days
Step 2: Calculate the demurrage Demurrage = Demurrage rate x Excess laytime Demurrage = $10,000/day x 2 days Demurrage = $20,000
Thus, in this example, the demurrage charge for MV Handybulk Oceanic is $20,000.
