In more specific terms….
The Principles Behind the EEDI CF is a non-dimensional conversion factor between fuel consumption measured in g and CO2 emission also measured in g based on carbon content. The subscripts MEi and AEi refer to the main and auxiliary engine respectively.
Vref is the ship speed through the water in the design condition measured in km/h at the output of the main engine as defined in this regulation and assuming the weather is calm with no wind and no waves.
DWT (Deadweight) means the difference in tonnes between the displacement of a ship in water of relative density of 1.025 at the load waterline corresponding to the assigned summer freeboard and the lightweight of the ship.
fj and fk are corrections to account for ship specific design elements such as, e.g., ice strengthening, cargo gear or reefer containers. fj and fk refer to main and auxiliary engine respectively.
SFC is the specific fuel consumption of the engines in the design condition measured in g/kWh. The subscripts MEi and AEi refer to the main and auxiliary engine respectively.
P is the installed power of the main and auxiliary engines in the design condition at a load of 100 % of the Maximum Continuous Rating (MCR) measured in kW. The subscripts ME and AE refer to main and auxiliary engine, respectively. The summation on i is for all engines with NME the number of main engines and NAE the number of auxiliary engines.
Capacity: For dry cargo, tankers, container ships and general cargo ships the capacity is the deadweight which is the difference in tonnes between the displacement of a ship in water of relative density of 1.025 at the load waterline corresponding to the assigned summer freeboard and the lightweight of the ship as defined in MARPOL Annex I, Regulation 1.23. For gas carriers the capacity is the tank-volume is the volume of gas carriers cargo tanks measured in cubic metres. For passenger ships, ro-ro passenger ships and ro-ro cargo ships the capacity is the gross tonnage in accordance with the International Convention on Tonnage measurement of ships 1969, Annex 1, regulation 3.

28. 28 Energy flow to be assessed to identify improvements for “ship as a system” The ship energy flow has to be assessed to identify the improvement areas for ships
Energy flow means mapping the purchased energy through all process to desired output. The energy flow for a whole ship is presented in a sankey diagram. You have probably seen similar diagrams and know that same illustration can be used for single process, e.g. engines.
Desired output for ships are thrust to propel the ship, el power and steam. The major losses are……………

32. 32 Drive for efficiency, cost reduction, improved energy efficiency & reduced CO2 emissions The intention behind this illustration is the fact that c CNG/PNG vessel will make gas fields that has been uneconomical available for commercial development. Gas is a clean energy that can be used for propulsion. Linked to the small LNG carrier a few slides in front of this.
