Abstract:
According to IMO, ships engaged in international trade in 1996 contributed about 1.8% of the total world’s CO2 emissions which is approximated as 2.7% in 2007 and this percentage could go two or three times higher by 2050 if present trend continues. In order to reduce CO2 emission, Marine Environment Protection Committee (MEPC) at its 62nd session adopted resolution MEPC.203(62) (MEPC, 2011a) which includes amendments to MARPOL Annex VI. It introduces new chapter which intends to improve energy efficiency for ships through a set of technical performance standards. The amendments, which entered into force on 1st January 2013, require that every ship has to comply with the Energy Efficiency Design Index (EEDI) and the Ship Energy Efficiency Management Plan (SEEMP). The EEDI is mandatory for all new ships and SEEMP for all ships of 400 GT and above engaged in the international shipping. Several attempts have been made to establish a reliable tool for seagoing vessels with respect to energy efficiency that can be found in various papers & reports. At the same time, many countries around the world are trying to develop some benchmarks for their inland shipping that could be used for assessment of the energy efficiency of inland waterway vessels. In Bangladesh, there are more than 10,000 different types of ship plying all the year round, but performance of these ships in terms of CO2 emission is not known and regulations related to the energy efficiency for inland waterway ships still does not exist. This is why this thesis attempts to assess and develop EEDI for inland vessels of Bangladesh.
To assess the present situation of inland class vessels in terms of EEDI, a database has been developed. Using the database, EEDI references lines for different types of inland vessels of Bangladesh have been established. Then the validation of the EEDI reference lines have been done and compared with other countries EEDI reference lines for inland vessels. The impact of design parameters on EEDI for different types of inland vessels of Bangladesh has been evaluated and the present status of existing inland vessels in terms of EEDI has been investigated. Furthermore, sensitivity analysis of inland vessels of Bangladesh has been performed in terms of EEDI considering socio-economic and technical factors in Bangladesh. The results indicate that most of the existing vessels do not meet the current EEDI baseline and so new guideline will be soon necessary for achieving EEDI compliance. Finally some recommendations have been proposed for assessment of the energy efficiency of different types of ship during design stage and trial/ performance test stage so that it can be helpful for Regulatory Authority to introduce some tools for EEDI for the inland shipping in Bangladesh in near future.
