Shut down the main engine in port during the loading and dislodging and use the shore connection Plug (this technique isoften referred to as cold ironing) would be a logical way to reduce CO2 emission below the legislative requirements aswell as get more environmental benefit such as decreasing fuel consumption.This paper presents the environmental benefit of the cold ironing through determining the amount of fuel oil consumptionand CO2 emission in three types of LNG carrier.To enable to estimate the amount of CO2 emitted from the ship, fuel consumption of ships on the berth by the Auxiliaryengine, boilers, fuel used for cargo work must be considered. This report will determine tones of CO2 emissions based onthe CO2 emission indexing from the LNG ships while running the auxiliary engine on the berth. To underline theimportance and relevance of the PLUG in GHG reduction, the amount of co2 emission in port of Fos Tonkin-France is alsocalculated as a case study. Total expected CO2 emissions reduction from a standard size of LNG vessel at berth wereestimated at 58 and 42 tons for 20 hours running auxiliary engine during unloading and loading respectively.
