Have you ever waited for a bus that didn’t arrive on time? Or sat on a train platform thinking, why don’t these trains arrive at the scheduled time? So, do you think that ships arrive on time to the ports?
In international shipping, time is everything. Every extra hour a ship spends her time at a port means lost money. Delays are not only financial losses but also disrupt global supply chains. Thus, ships must arrive, load, discharge, and sail again without delay. But when things don’t go as planned, costs begin to build up.
That’s where the terms demurrage, dispatch, and detention come into play. Think of these terms as a “time management tool” in shipping. When you delay, you have to pay. When you save time, you earn. In simple words. Time lost is money lost, and time saved is money gained.
These are three of the most commonly used words in shipping contracts. But they often confuse newcomers in the industry. Understanding these terms helps both shippers and receivers to manage their operations efficiently and avoid unnecessary expenses. Let’s see what these terms are.
What Is Demurrage?
Let’s start with Demurrage. This is one of the most commonly used and most misunderstood words in shipping.
Definition
In simple terms, demurrage is a charge for delay. It is the fee you pay when a ship, or a container, stays at the port longer than the agreed time. This is like paying rent for extra time used at the port.
When a ship arrives at a port, both the shipowner and the charterer agree on a fixed number of days for loading or unloading cargo. We call this period laytime. When cargo operations go beyond it, the shipowner charges demurrage for every additional day the vessel remains in port.
Example of Demurrage
Imagine a bulk carrier arrives at the Port of Colombo to discharge 30,000 tonnes of rice. The laytime is 5 days for unloading. However, due to equipment failure, it takes 7 days. The extra 2 days count as demurrage.
If the agreed demurrage rate is $2000 per day, the total payment should be $4000. Simply, it is because the ship stayed at the berth longer than planned.
Why Is Demurrage Charged?
The purpose of demurrage is not to punish It is to ensure that ships aren’t waiting unnecessarily at ports. Each extra day a ship spends in port costs the shipowner time that could earn money on another voyage. Demurrage acts as a financial penalty to encourage efficient cargo handling and minimize delays.
Demurrage in Container Shipping
In containerized shipping, demurrage applies when a container stays inside the port beyond the allowed free storage days. For example, if the port allows five free days and the container remains for ten days and the port charges demurrage for the extra five days.
Common Issues for Demurrage
- Port congestion or labor strikes
- Bad weather conditions like rain, storms, fog
- Lack of equipment like cranes or trucks
- Poor coordination between agents and stevedores
- Equipment failures
What Is Despatch?
Now let’s move to the despatch. Despatch is the opposite of demurrage.
If demurrage is a penalty for being late, then despatch is a reward. It is like a bonus paid to the charterer when loading or unloading finishes earlier than the agreed laytime.

Example of Despatch
Say a vessel has 6 days of laytime to load cargo. The operation finishes in 4 days, saving 2 days. The shipowner pays despatch money to the charterer. Usually, the despatch rate is half of the demurrage rate.
If the demurrage rate is $2000 per day, despatch rate would be $1000 per day.
Why Despatch Matters
Despatch encourages charterers, stevedores, and terminal operators to handle cargo swiftly and efficiently.
- Shipowners can depart early and take another job.
- Charterers receive a reward for efficiency.
- Ports experience less congestion
- Trade flow becomes faster and smoother.
What Is Detention?
Detention is another time-related charge. It applies mainly in container shipping. Detention refers to a penalty for delay outside the port.
After the consignee picks up the container from the terminal, the shipping line allows a fixed number of free days to return. Usually it is between 5 to 7 days. If the consignee or importer keeps the container longer, detention fees start to apply.
Example of Detention
Imagine you’re an importer. You pick up a container from the Colombo Port on the 1st of the month. The shipping line gives you seven free days to return the container. However, due to a delay, you have to return the container on the 10th of the month. There are 3 days of delays, and these 3 extra days count as detention. The shipping line charges for each late date.
Why Detention Is Charged
Containers are valuable assets owned by shipping lines. Each shipping line has a limited number of containers. If consignees hold containers too long, it causes equipment shortages and disrupts the flow of trade. Thus, detention is charged;
- In order to make sure containers circulate quickly and are available for other shipments.
- To prevent importers from using containers as temporary storage.
- To maintain the flow of container supply around the world.
Difference Between Demurrage, Despatch, and Detention
Now that you understand the three terms individually. Although these three terms are closely related, they serve different purposes in shipping contracts.
| Aspect | Demurrage | Despatch | Detention |
|---|---|---|---|
| Definition | Penalty for exceeding laytime during loading/unloading | Reward for completing operations before laytime expires | Penalty for keeping containers or equipment beyond free time |
| Who Pays? | Charterer or consignee (importer/exporter) | Shipowner | Consignee or shipper |
| Where It Applies | Inside the port | Inside the port | Outside the port |
| Type | Penalty | Reward | Penalty |
| Purpose | Compensate for delay. | Encourage efficiency. | Ensure container circulation. |
Demurrage and dispatch apply mainly to bulk shipping under a charter party. Detention and demurrage (in the container context) apply to containerized trade under bill of lading terms. Together all three are connected to time.
Final Thought
Shipping is a time-bound industry. A small delay at one port affects shipping schedules across multiple countries. That’s why demurrage, dispatch, and detention play such an important role in maritime logistics. Together, these three principles create balance in the shipping world.
So next time when you hear about a ship waiting at port, think beyond the waves and cranes. Behind every delay or early completion there is a financial story.
Frequently Asked Questions (FAQ)
Laytime is the agreed number of free days or hours allowed for loading or discharging cargo at a port. Once laytime ends, the shipowner applies demurrage if the work still continues.
This depends on the type of charter party. However, in most modern contracts, dispatch is standard practice, as it benefits both parties.
The charterer or consignee pays demurrage to the shipowner. They cover the cost of extra time the ship spends in port.
The shipowner pays dispatch when the charterer finishes loading or unloading early. The rate is usually half of the daily demurrage rate.
Yes. Plan cargo readiness carefully, ensure timely customs clearance, and coordinate with port agents to finish operations on time.
Yes, they can be negotiated before signing the contract. The rates and free days vary depending on trade routes, port conditions, and the relationship between shipper and carrier.
Weather delays, known as “weather working days.” It may or may not count toward laytime. This depends on the contract. Some agreements exclude weather delays, while others count them as part of total laytime.
