Marine energy management
Encyclopedia
Marine energy management is the application of systematic methods to measure, register and analyze the energy usage of ocean going vessels in specific.
The goal of marine energy management is to
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, the auxiliary engines, refrigeration systems, HVAC
, etc. The weather and sea-state, plus the logistics
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.
The goal of marine energy management is to
- maximize the (electrical or mechanical) energy generated from the minimum amount of fossil fuelFossil fuelFossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years...

Logistics
Logistics is the management of the flow of goods between the point of origin and the point of destination in order to meet the requirements of customers or corporations. Logistics involves the integration of information, transportation, inventory, warehousing, material handling, and packaging, and...
