Energy efficiency design index baselines for ships of Bangladesh based on verified ship data

Abstract

To establish Energy Efficiency Design Index (EEDI) baselines, correct ship data must be used. International Maritime Organization (IMO) used correct ship data from the ‘IHS Fair play database’ to develop EEDI baselines. Like IMO, Bangladeshi inland ship data are also available in several Government organizations. Unfortunately, investigations and field studies have found that the actual measurement varies from the available design data. The deviations are found mostly in the principal particulars, main and auxiliary engine powers, and design speed. All this deviated ship information has a high influence on EEDI values. For this reason, ship data should be verified to find the correct ones and it is the key factor to establish correct EEDI baselines for inland ships of Bangladesh. 2247 inland ships' data of Bangladesh have been investigated out of which, 1643 numbers of ship data could not be used to establish EEDI baselines due to ambiguous and faulty data. EEDI baselines represent the status of CO2 emission per tonne mile. To quantify that amount, actual ship operational data are required. Using verified ships' physical and operational data, EEDI baselines for Inland Cargo, Oil Tanker and Passenger Ships of Bangladesh have been proposed in this research.
