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 book 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. Finally some recommendations have been proposed for assessment of EEDI of different types of ship during design stage.
