One of the key tasks for human being to take seems to be the reduction of fossil fuel consumption in order to save our planet from the disaster caused be climate changes. World wide effort to reduce fossil fuel consumption seems to be enforced. Accordingly, Korean government implemented the basic law for low carbon green growth in January 2010, and detailed guideline followed in March 2011.
In the field of shipping industry the government launched a second stage pilot project of vessel green gas reduction in which 2 companies participated. In 2015 EEDI was applied to the newly building vessels to achieve the target of 37% green gas reduction up to 2030.
This study, therefore, tried to analyse the characteristics of fuel consumption and green gas emission of coastal vessels based on the empirical data gathered from a domestic company. For this vessel operating data containing sailing distance, port time, sailing time, speed, cargo loading ratio etc. were gathered for 12 vessels for the period of 5 years.
The analysis revealed some meaningful results and based on them some implication for the reduction of vessel green gas emission.
