DETERMINATION AND SOLUTIONS TO IMPROVE ENERGY EFFICIENCY EXISTING SHIP INDEX VIET THUAN 30-02

Abstract

The application of the Energy Efficiency Index for Existing Ships (EEXI) is one of the solutions to limit CO₂ emissions from ships in order to reduce CO₂ emissions from ships by 70% by 2050 compared to CO₂ emissions in 2008. According to the provisions of MARPOL Annex VI 73/78, the application of the EEXI index officially took effect on January 1, 2023. Therefore, the determination of the EEXI index as well as the application of measures to improve the EEXI index for ships to be eligible for operation when the law applying the EEXI index comes into effect is an urgent issue for ship owners. This article presents how to determine the EEXI index for the Viet Thuan 30-02 ship, as well as analyze solutions to improve the EEXI index for the ship. The results of the article have shown that the EEXI index of Viet Thuat 30-02 vessel without any improvement measures is 7.05g-CO₂/ton-mile, which is 26% higher than the required EEXI index (5.58g-CO₂/ton-mile). miles). The most effective measure to improve the EEXI index is to reduce the operating speed of the vessel. This is an environmentally and economically viable solution when applied correctly.
