Cargo ships burn between 20 and 400 tons of fuel per day, depending on ship size, speed, and engine type — a large container ship can use as much fuel in a day as roughly 1,000 cars. This guide breaks down real consumption figures by ship type, what drives that number up or down, and how operators are cutting it.
What Is the Average Fuel Consumption by Ship Size?
Fuel consumption depends heavily on ship type and the speed it operates at. The table below breaks down typical daily consumption by category.
Container Ship Fuel Consumption
| Container Ship Type | Ship Capacity (TEU) | Fuel Consumption per Day (metric tons) |
|---|---|---|
| Small feeder | Up to 1,000 | 5-40 mt/day |
| Feeder | 1,001–2,000 | 20-70 mt/day |
| Feedermax | 2,001–3,000 | 40-100 mt/day |
| Panamax | 3,001–5,100 | 50-200 mt/day |
| Post-Panamax | 5,101–10,000 | 100-250 mt/day |
| New Panamax (or Neopanamax) | 10,000–14,500 | 100-250 mt/day |
| Ultra Large Container Vessel (ULCV) | 14,501 and higher | 200-400 mt/day |
Real-world examples give a clearer picture than averages alone.
CV ELBELLA
CV ELBELLA is a self-sustained cellular container vessel built in 2006, with a summer deadweight of about 23,351 MT and a capacity of 1,740 TEU — classed as a feeder container ship. At about 20 knots, it consumes approximately 60 MT of IFO plus 4.0 MT for auxiliary engines.

Fuel Consumption Per Nautical Mile
Daily consumption figures don’t account for how far a ship actually travels in a day — per-mile figures normalize for that, useful when comparing routes or voyage costs directly.

|---|---|---|---|---|
| Feeder Container Ship | 500 TEU, 15 kn | 15–20 | 0.6–0.8 | 0.041–0.055 |

Fuel Types Used on Cargo Ships
Most cargo ships run on heavy fuel oil (HFO) or marine gas oil (MGO), with LNG and biofuels gaining ground under tightening emissions rules.
- Heavy Fuel Oil (HFO) — the most common, roughly 80% of fuel burned fleet-wide. Cheap, but high in sulfur and other pollutants.
- Marine Gas Oil (MGO) — lighter, lower-sulfur, more expensive than HFO. Standard inside Emission Control Areas (ECAs) in North America and Europe.
- Liquefied Natural Gas (LNG) — cleanest-burning of the mainstream options, but requires dedicated equipment and limited bunkering infrastructure.
- Biodiesel — renewable, biodegradable, but costlier than HFO/MGO and not yet widely adopted.
- Hydrogen — zero-emissions, but expensive to produce and requires significant new infrastructure.
- Methane — lower emissions than fossil fuels, produced from biomass or natural gas, still an emerging option.
What Factors Influence Ship Fuel Consumption?
Ship size and weight: larger, heavier ships need more power to move, so they burn more fuel. The Emma Maersk, one of the world’s largest container ships, carries up to 15,500 TEU and burns roughly 250 tons/day at 25 knots — against 20–25 tons/day for a Handysize ship at 12 knots.
Engine type and efficiency: diesel engines dominate the industry for reliability and efficiency. Gas turbines can use up to 30% less fuel but cost more to operate; steam turbines are largely obsolete except on some LNG carriers.
Speed: fuel use rises sharply with speed — a ship burning 10–20 tons/day at 10 knots can jump to 50–100 tons/day at 20 knots. The relationship isn’t perfectly linear, since hull resistance drops as speed increases past a certain point, but as a rule, faster costs more.
Weather and sea state: rough seas and strong currents increase resistance. A ship burning 30–50 tons/day at 15 knots in calm water can rise to 70–100 tons/day in heavy seas.
Cargo operations and heating: running cranes and pumps during loading/unloading adds 2–5 tons/hour on a 50,000-ton vessel. Heating viscous cargo like heavy fuel oil to 60°C can add 0.5–1 ton/hour — up to 120–240 tons across a 10-day voyage.
Fuel Efficiency Improvements
- Slow steaming — reducing speed can cut fuel use by up to 30%, at the cost of longer transit times.
- Hull coatings — low-friction coatings can reduce fuel consumption by up to 10% by cutting drag.
- Propeller design — optimized pitch, diameter, and materials can save up to 5% on fuel.
- Fuel switching — moving from HFO to MGO or LNG cuts emissions, though at higher fuel cost and infrastructure requirements.
- Engine upgrades — modern or retrofitted engines can deliver fuel savings of up to 20%.
Environmental Impact of Cargo Ship Fuel Consumption
Shipping accounts for about 2.5% of global greenhouse gas emissions, according to the International Maritime Organization (IMO), driven mainly by CO2 emissions from heavy fuel oil. The IMO has set a target of cutting shipping emissions at least 50% by 2050 versus 2008 levels under MARPOL and related energy-efficiency standards, driving industry interest in LNG, biofuels, and alternative propulsion.
Frequently Asked Questions
How much fuel does a cargo ship use per hour?
It varies widely by size — a feeder container ship burns roughly 0.6–0.8 tons per hour, while a large New Panamax container ship at speed can use 6–8 tons per hour.
What is marine fuel consumption measured in?
Typically metric tons per day, though per-hour and per-nautical-mile figures are also used to compare vessels or estimate voyage costs.
How much fuel does a container ship use?
A small feeder (up to 1,000 TEU) uses roughly 5–40 tons per day, while an Ultra Large Container Vessel (14,500+ TEU) can burn 200–400 tons per day depending on speed.
What fuel do most cargo ships use?
Heavy fuel oil (HFO) accounts for roughly 80% of fuel burned across the global fleet, with marine gas oil (MGO) required in Emission Control Areas and LNG adoption growing.
How can cargo ships reduce fuel consumption?
The most effective methods are slow steaming (up to 30% savings), hull coatings (up to 10%), and engine upgrades (up to 20%), often combined for compounding effect.
