Distribution of energy efficiency design index for tankers in Indonesia

Abstract

Greenhouse gas emissions resulting from shipping activities increased by 9% in 2018. Tankers are one of the contributors to total ship emissions. To reduce these emissions, the International Maritime Organization adopted the Green House Gas Strategy by issuing a regulation in the form of the Energy Efficiency Design Index (EEDI). This study aims to obtain the distribution of EEDI tankers in Indonesia. The EEDI calculation uses empirical equations that consider the main engine power, auxiliary engine power, and reference speed. The ship data used are 638 units of Indonesian-flagged tankers, including ship particulars from the classification agency. The results of this study indicate that compliance with the EEDI regulation is 26%. Through the application of engine power limitation technology and innovative technology in the form of weather routing, waste heat recovery, solar panels, and electronically controlled engines, EEDI fulfillment increased to 78%.
