Marine energy management is the application of systematic methods to measure, register and analyze the energy usage of oceangoing vessels in specific.
The goal of marine energy management is to
*''maximize the (electrical or mechanical) energy generated from the minimum amount of
fossil fuel
A fossil fuel is a hydrocarbon-containing material formed naturally in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, oil, and natural gas. Fossil fuels m ...
'', and
*''maximize the useful work obtained from the minimum amount of generated energy''. The IMO is the international body responsible for code regulation.
These are two separated optimization problems.
Marine energy management can both be applied on board and onshore. It is a complex problem, due to the number of inter-related energy systems on board vessels, such as the
propulsion
Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. The term is derived from ...

HVAC
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HV ...

logistics
Logistics is generally the detailed organization and implementation of a complex operation. In a general business sense, logistics manages the flow of goods between the point of origin and the point of consumption to meet the requirements of ...
involved in transporting goods from one port to another, also have big effects.
Marine energy management can be addressed on board through measuring devices, monitoring systems and decision-support systems. It can be addressed onshore through data analysis, leading to change in operation on board.
