Abstract

Indikator penting untuk mengevaluasi efisiensi energi kapal adalah Indeks Desain Efisiensi Energi (EEDI), yang juga penting untuk mengurangi emisi gas rumah kaca di sektor maritim. Studi ini meneliti bagaimana ukuran dan kecepatan memengaruhi nilai EEDI kapal LNG. Mengangkut gas alam cair memerlukan kapal pengangkut LNG, dan cara kapal ini dibangun berdampak langsung pada emisi dan konsumsi bahan bakar. Studi ini menyelidiki dampak beberapa variabel pada EEDI, termasuk ukuran kapal (termasuk kapasitas dan tonase) dan kecepatan operasional. Studi ini meneliti hubungan antara ukuran kapal dan penghematan bahan bakar dengan memeriksa beberapa desain kapal pengangkut LNG, dengan mempertimbangkan kapal yang lebih besar dan lebih kecil. Selain itu, karena kecepatan operasional berdampak signifikan pada emisi dan konsumsi bahan bakar, dampak kecepatan yang berbeda pada EEDI keseluruhan diperiksa. Temuan analisis ini dimaksudkan untuk memberikan informasi penting kepada pembuat dan operator kapal untuk membuat kapal pengangkut LNG yang lebih hemat energi, memenuhi standar lingkungan, dan terus berfungsi secara efektif. Dengan menyarankan teknik pengoptimalan desain yang menyeimbangkan ukuran, kecepatan, dan efisiensi energi, studi ini pada akhirnya berupaya mendukung upaya berkelanjutan untuk mengurangi jejak karbon industri pelayaran, khususnya di sektor transportasi LNG. Studi ini menyoroti perlunya strategi desain kapal yang kreatif untuk meningkatkan efisiensi energi dan mendukung masa depan maritim yang lebih berkelanjutan.

An important indicator for evaluating the energy efficiency of a ship is the Energy Efficiency Design Index (EEDI), which is also important for reducing greenhouse gas emissions in the maritime sector. This study examines how size and speed affect the EEDI value of LNG ships. Transporting liquefied natural gas requires LNG carriers, and the way these ships are constructed has a direct impact on emissions and fuel consumption. This study investigates the impact of several variables on the EEDI, including ship size (including capacity and tonnage) and operational speed. The study examines the relationship between ship size and fuel economy by examining several LNG carrier designs, considering both larger and smaller vessels. In addition, since operational speed has a significant impact on emissions and fuel consumption, the impact of different speeds on the overall EEDI is examined. The findings of this analysis are intended to provide shipbuilders and operators with important information to create LNG carriers that are more energy efficient, meet environmental standards, and continue to function effectively. By suggesting design optimization techniques that balance size, speed, and energy efficiency, this study ultimately seeks to support ongoing efforts to reduce the carbon footprint of the shipping industry, especially in the LNG transportation sector. This study highlights the need for creative ship design strategies to improve energy efficiency and support a more sustainable maritime future.
