Abstract
The increase of heat in the Earth’s atmosphere caused by greenhouse gases emissions has changed the natural climate variability, resulting in the climate change. According to the Third IMO GHG Study 2014, international shipping has emitted 866 million tonnes of GHG per year on average between 2007 and 2012 which represented approximately 2.4% of global GHG emissions. In order to mandatorily implement the ship fuel consumption data collection and reporting scheme, IMO adopted amendments to MARPOL Annex VI on data collection system for fuel oil consumption of ships by the resolution MEPC.278 (70), in which a new Regulation 22A-Collection and reporting of ship fuel oil consumption data” was added, requiring that each ship of 5,000 gross tonnage and above, from calendar year 2019, shall collect the fuel consumption data as specified and report to its flag state. In order to implement properly the new regulations, this paper, supported by “a pilot project of shipboard fuel consumption data collection”, systematically analyses the IMO requirements for ship fuel consumption data collections and data collection methods. And based on the shipboard real practices and experiences, the whole process of data collection is demonstrated, and precautions and suggestions for more accurate data collection are also provided, for the easy reference by parties concerned such as ship masters, ship owners, managers, maritime authorities, etc.
Highlights
Human activities, in particular the rising fossil fuel combustion, have directly emitted growing amounts of greenhouse gases (GHG) into the Earth’s atmosphere
In order to mandatorily implement the ship fuel consumption data collection and reporting scheme, IMO adopted amendments to MARPOL Annex VI on data collection system for fuel oil consumption of ships through the resolution MEPC.278 (70), which entered into force on 1 March 2018
The annual accurate amount of CO2 emissions from ships is one of the most important bases for the international shipping sector to scientifically develop the strategy of reducing the GHG emissions from ships, assess the implementation effectiveness of current mandatory regulations and introduce new mandatory regulations
Summary
In particular the rising fossil fuel combustion, have directly emitted growing amounts of greenhouse gases (GHG) into the Earth’s atmosphere. It is indispensable that the international shipping industry shall take necessary actions to effectively limit and reduce the GHG emissions from ships in order to help achieve the goal in controlling the rise of global surface temperature which is laid down in the Paris Agreement to The United Nations Framework Convention on Climate Change (UNFCCC). [3] A new "Regulation 22A-Collection and reporting of ship fuel oil consumption data” was added after existing regulation 22, MARPOL 73/78 Annex VI chapter 4, requiring that “each ship of 5,000 gross tonnage and above, from calendar year 2019, shall collect the data specified in appendix IX to the Annex, for that and each subsequent calendar year or portion thereof, as appropriate, according to the methodology included in the SEEMP.” [4]. Based on the shipboard real practices and experiences, the whole process of data collection is demonstrated, and precautions and suggestions for more accurate data collection are provided, for the easy reference by parties concerned such as ship masters, ship owners, managers, maritime authorities, etc
