Abstract

Pemilihan konfigurasi mesin induk yang tepat memainkan peran krusial dalam mengoptimalkan kinerja operasional dan efisiensi ekonomi kapal tanker minyak berbahan bakar diesel konvensional. Penelitian ini bertujuan untuk mengevaluasi dan membandingkan konfigurasi mesin tunggal dan mesin ganda melalui pendekatan analisis teknis dan ekonomi, dengan menggunakan MT. Senipah sebagai objek penelitian. Metodologi penelitian dimulai dengan perhitungan koefisien kapal, hambatan, dan kebutuhan daya, untuk menentukan spesifikasi mesin yang sesuai dengan karakteristik dan profil operasional kapal. Selanjutnya, penelitian ini menganalisis parameter kinerja operasional seperti akselerasi, redundansi, dan keandalan pada kedua konfigurasi mesin, termasuk respons terhadap kegagalan mesin. Analisis teknis ini dilengkapi dengan evaluasi aspek ekonomi melalui penghitungan pengeluaran operasional (OPEX), yang mencakup konsumsi bahan bakar, biaya perawatan rutin dan darurat, kebutuhan suku cadang, serta biaya awak kapal. Faktor eksternal seperti premi asuransi, dan regulasi internasional yang mengatur terkait emisi juga dianalisis sebagai bagian dari pertimbangan pada penelitian ini. Analisis komparatif ini mengungkap trade-off antara biaya operasional jangka panjang, dan tingkat redundansi sistem. Konfigurasi mesin tunggal menunjukkan keunggulan dalam efisiensi bahan bakar dan sistem yang sederhana, namun rentan terhadap risiko operasional akibat kurangnya cadangan tenaga. Sementara itu, konfigurasi mesin ganda menawarkan redundansi tinggi dan fleksibilitas operasional yang lebih baik, tetapi memerlukan sumber daya yang lebih besar untuk biaya perawatan, ruang mesin,dan kompleksitas pengoperasian.Temuan ini diharapkan dapat menjadi panduan strategis dalam memahami faktor-faktor penting yang perlu dipertimbangkan saat memilih konfigurasi mesin induk. Penelitian ini juga berkontribusi pada pengembangan praktik operasional kapal yang lebih berkelanjutan dan ekonomis, sejalan dengan kebutuhan industri maritim modern yang menuntut keseimbangan antara efisiensi, keandalan, dan efektivitas biaya.

The selection of an appropriate main engine configuration plays a critical role in optimizing the operational performance and economic efficiency of conventional diesel-powered oil tankers. This study aims to evaluate and compare single and dual engine configurations through technical and economic analyses, using the MT. Senipah as the research subject. The methodology begins with calculating the ship’s coefficients, resistance, and power requirements to determine engine specifications aligned with the vessel’s characteristics and operational profile. Subsequently, the study analyzes operational performance parameters such as acceleration, redundancy, and reliability for both engine configurations, including responses to engine failure. The technical analysis is supplemented by an economic evaluation of operational expenditure (OPEX), encompassing fuel consumption, routine and emergency maintenance costs, spare parts requirements, and crew-related expenses. External factors such as insurance and international emission regulations are also analyzed as part of the research considerations. This comparative analysis reveals trade-off between long-term operational costs and system reliability levels. The single engine configuration demonstrates advantages in fuel efficiency and system simplicity but is vulnerable to operational risks due to insufficient backup power. Meanwhile, the dual engine configuration offers higher redundancy and operational flexibility but requires greater resources for maintenance costs, engine room, and operational complexity. These findings are intended to serve as a strategic guide for understanding critical factors in selecting main engine configurations. The study also contributes to the development of more sustainable and cost-effective maritime operational practices, aligning with the modern maritime industry’s demand for a balance between efficiency, reliability, and cost-effectiveness.
