The concept of “green ship”: New developments and technologies

© 2017 Taylor & Francis Group, London, UK.Ocean-borne trade has increased steadily over the past few decades and is expected to continue to play a crucial role in the globalized world economy. This growth has brought with air quality and marine pollution problems and global climate change risks unless ship emissions are controlled. Thus, International Maritime Organization (IMO) aims to guide to the sectors how to reduce carbon footprint by technical and operational measures. IMO also emphasize on the importance of a global approach in advanced improvements to energy efficiency and emission reduction. This approach led to maritime industry to seek for new technological developments to reduce ship-based CO2, NOx and SOx emissions, to improve energy efficiency and to develop propulsion power such as sulphur scrubber system, LNG fuel for propulsion, advanced rudder and propulsion system and etc. The purpose of this paper is to examine aforementioned new technological developments and to discuss the advantages and disadvantages of them
