Container ship engine shaft power
Container ship engine shaft power is the mechanical power transmitted from a ship’s main engine to its propeller for movement through water.
Also known as: container ship propulsion power

A little perspective
Container ship engine shaft power vs Cruise ship hotel electrical load: power comparison
The engine shaft power of a container ship is about 1.2 times the hotel electrical load of a cruise ship.
ENERGY EACH SECOND
Container ship engine shaft power is the mechanical power transmitted from a ship’s main engine to its propeller for movement through water.
Cruise ship hotel electrical load is the electrical power required to operate accommodation and guest services on a cruise ship, excluding propulsion.
Measurements, assumptions & sources +
Container ship engine shaft power
Defined large-engine shaft output: 60 MW; defined calculation; range 40 MW–80 MW.
A defined 60 MW shaft-power scale for a large slow-speed container-ship diesel engine near rated output. It is mechanical output, not fuel heat input, and ships operate below rating much of the time.
Defined examples — our methodology
The marked defined large-engine shaft output is calibrated. Unmeasured illustration details are representative.
Cruise ship hotel electrical load
Defined hotel-load power: 50 MW; defined calculation; range 20 MW–100 MW.
A defined 50 MW electrical hotel load for a very large cruise ship, covering accommodation and guest services rather than propulsion. Vessel size, occupancy and operating conditions dominate the actual load.

Why this measurement?
Why we use 60 MW
We compare the engine shaft power of a container ship. This is calculated from stated inputs and assumptions, not a direct measurement. The recorded range is 40 MW to 80 MW.
A defined 60 MW shaft-power scale for a large slow-speed container-ship diesel engine near rated output. It is mechanical output, not fuel heat input, and ships operate below rating much of the time.
