A historical reconstruction of ships' fuel consumption and emissions [PDF]
Shipping activity has increased considerably over the last century and currently represents a significant contribution to the global emissions of pollutants and greenhouse gases. Despite this, information about the historical development of fuel consumption and emissions is generally limited, with little data published pre‐1950 and large deviations ...

Operational of ship influences the running cost. A old ship, day by day cash cost are higher with ageing machinery requiring constant maintenance, a rusty hull requiring regular steel replacement and high fuel oil consumption.

Ship Speed Control to Minimize Fuel Consumption
When a ship runs a fixed route in a given time, two methods are proposed to reduce the fuel consumption of the ship. The first optimization policy is to keep the engine output power at a constant level, in spite of prevailing conditions, such as wind forces, wind directions, sea conditions, draft, fouling, etc.
