Abstract

Studi ini mengkaji kelayakan konversi sistem propulsi kapal tanker konvensional dengan kapasitas 17.500 (DWT) menjadi konfigurasi hybrid untuk tujuan dekarbonisasi emisi kapal. Penilaian teknis mengevaluasi kemampuan mesin untuk operasi power take-off (PTO), power take-in (PTI), dan power take-home (PTH), dengan mempertimbangkan batas tata letak PTO dan penggunaan shaft generator dalam kondisi laden dan ballast. Hasil dari penilaian teknis menunjukkan bahwa kapal tanker 17500 DWT, yang dilengkapi dengan sistem propulsi hybrid, dapat mematuhi sstandar IMO Indeks Desain Efisiensi Energi (EEDI) fase 1. Selain itu, analisis konsumsi bahan bakar mengungkapkan bahwa penerapan sistem propulsi hybrid pada kapal tanker 17500 DWT dapat menghemat bahan bakar sebesar 5-11% dalam kondisi laden dan 11-20% dalam kondisi ballast. Analisis risiko kuantitatif dilakukan menggunakan metode Failure Modes and Effects Analysis (FMEA) dengan standar DNV GL untuk baterai, guna menilai risiko yang terkait dengan sistem hybrid. Penelitian mengidentifikasi 19 moda kegagalan, di mana 15 di antaranya dinilai memiliki kriteria risiko yang tidak dapat diterima. Tindakan mitigasi risiko dikembangkan, termasuk merancang ruang baterai dengan beberapa langkah pencegahan untuk mengurangi probabilitas dan tingkat keparahan insiden thermal runaway pada baterai lithium. Analisis risiko kuantitatif menunjukkan bahwa tingkat risiko yang dihasilkan berada dalam batas yang dapat diterima dibandingkan dengan standar UK HSE. Analisis ekonomi mengungkapkan Internal Rate of Return (IRR) sebesar 13%, periode pengembalian modal 10 tahun, dan nilai Net Present Value (NPV) hingga 400.000 USD. Penilaian komprehensif ini memberikan wawasan mengenai aspek teknis, risiko, dan ekonomi dari konversi sistem propulsi hybrid, serta berkontribusi pada diskusi internasional tentang dekarbonisasi dalam industri maritim.

This study examines the feasibility of converting the propulsion system of a conventional 17,500 deadweight tonnage (DWT) tanker ship into a hybrid configuration for decarbonization purposes. The technical assessment evaluates engine capabilities for power take-off (PTO), power take-in (PTI), and power take-home (PTH) operations, considering PTO layout limits and the use of a shaft generator in laden and ballast conditions. The results of the technical assessment indicate that the 17500 DWT tanker ship, equipped with a hybrid propulsion system, can comply with the phase 1 Energy Efficiency Design Index (EEDI) requirements. Furthermore, fuel consumption analysis revealed that implementing a hybrid propulsion system on the 17500 DWT tanker ship can lead to fuel savings of 5-11% in laden conditions and 11- 20% in ballast conditions. A quantitative risk analysis was conducted using Failure Modes and Effects Analysis (FMEA) with DNV GL standards for batteries to assess the risks associated with the hybrid system. The research identified 19 failure modes, of which 15 were deemed to have unacceptable risk criteria. Risk mitigation measures were developed, including designing a battery room with multiple safeguards to reduce the probability and severity of lithium battery thermal runaway incidents. The quantitative risk analysis demonstrated that the resulting risk levels were within acceptable limits compared to UK HSE standards. Economic analysis reveals a 13% internal rate of return (IRR), a 10-year payback period, and up to $400,000 USD net present value (NPV). This comprehensive assessment offers insights into the technical, risk, and economic aspects of hybrid propulsion system conversion, contributing to international discussions on decarbonization in the maritime industry.
