Abstract

Industri pelayaran global menghadapi tuntutan peningkatan efisiensi energi dan pengurangan emisi gas rumah kaca seiring diberlakukannya regulasi International Maritime Organization (IMO), seperti MARPOL Annex VI dan IMO 2020. Salah satu upaya yang dapat dilakukan adalah penerapan sistem kelistrikan hybrid dengan memanfaatkan shaft generator pada mode Power Take-Off (PTO) yang dikombinasikan dengan Battery Energy Storage System (BESS) untuk mengurangi ketergantungan terhadap auxiliary generator berbahan bakar diesel. Penelitian ini bertujuan menganalisis penerapan Energy Management System (EMS) pada sistem hybrid diesel–listrik berbasis shaft generator dan BESS pada kapal LPG Carrier MT Pertamina Gas Dahlia berkapasitas 91.000 CBM. Metode penelitian meliputi pengumpulan data teknis kapal, analisis load balance, pemodelan sistem menggunakan MATLAB/Simulink, serta simulasi pada kondisi operasi Sea Going, Maneuvering, Cargo Handling, dan Anchoring. Hasil simulasi menunjukkan bahwa pada kondisi Sea Going, shaft generator mampu mengisi BESS sebesar 735 kWh dari SOC 20% menjadi 90% dalam waktu 2,45 jam. Pada kondisi Maneuvering, Cargo Handling, dan Anchoring, BESS mampu menyuplai daya masing-masing sebesar 134 kW, 62,5 kW, dan 433,1 kW, sehingga konsumsi bahan bakar diesel berkurang sebesar 0,18 ton fuel (13,8%), 0,472 ton fuel (15,7%), dan 0,184 ton fuel (10,8%). Pengisian ulang BESS menggunakan Emergency Generator berdaya 300 kW memerlukan waktu 2,45 jam dengan estimasi konsumsi bahan bakar sekitar 0,143 ton fuel. Berdasarkan hasil tersebut, penerapan sistem hybrid berbasis shaft generator dan BESS yang dikendalikan oleh EMS berpotensi meningkatkan efisiensi operasional sistem kelistrikan kapal melalui pengurangan konsumsi bahan bakar generator diesel serta menjaga kontinuitas pasokan daya pada berbagai kondisi operasi.

The global shipping industry is facing increasing demands to improve energy efficiency and reduce greenhouse gas emissions in response to the implementation of international regulations, such as IMO MARPOL Annex VI and the IMO 2020 sulfur cap. One promising solution is the application of a hybrid marine power system by utilizing a Power Take-Off (PTO) shaft generator integrated with a Battery Energy Storage System (BESS) to reduce dependence on diesel-driven auxiliary generators. This study aims to analyze the implementation of an Energy Management System (EMS) for a hybrid diesel-electric power system based on a PTO shaft generator and BESS on the 91,000 CBM LPG Carrier MT Pertamina Gas Dahlia. The research methodology includes technical data collection, load balance analysis, system modeling using MATLAB/Simulink, and simulation under four operating conditions: Sea Going, Maneuvering, Cargo Handling, and Anchoring. The simulation results show that during the Sea Going condition, the shaft generator successfully charges the BESS with 735 kWh, increasing the battery State of Charge (SOC) from 20% to 90% within 2.45 hours. During the Maneuvering, Cargo Handling, and Anchoring conditions, the BESS supplies 134 kW, 62.5 kW, and 433.1 kW, respectively, resulting in diesel fuel savings of 0.18 tons (13.8%), 0.472 tons (15.7%), and 0.184 tons (10.8%). In addition, recharging the BESS using a 300 kW Emergency Generator requires approximately 2.45 hours, with an estimated diesel fuel consumption of 0.143 tons. These results indicate that the proposed EMS-based hybrid power system has the potential to improve the operational efficiency of the ship's electrical power system by reducing diesel fuel consumption while maintaining a reliable power supply under various operating conditions
