Abstract

Pengangkutan kendaraan listrik pada kapal Ro-Ro memerlukan penilaian keselamatan kebakaran yang cermat karena kebakaran baterai lithium-ion dapat mempertahankan pemanasan lokal yang tinggi, menghasilkan asap, dan menurunkan jarak pandang pada geladak kendaraan. Penelitian ini membandingkan model Fire Dynamics Simulator untuk kebakaran kendaraan listrik pada Deck D dan Deck E KM Dharma Kencana V. Kedua skenario menggunakan geometri kendaraan, susunan baterai sembilan modul, definisi material, metode propagasi berbasis temperatur, dan resolusi nominal sel Cartesian yang sama. Modul 5 ditetapkan sebagai sumber awal, sedangkan modul lainnya aktif ketika temperatur lokal mencapai 120 °C. Water curtain aktif pada 180,043 detik di Deck D dan 180,033 detik di Deck E. Deck D menggunakan 18 nozzle dengan debit nominal total 324 L/menit, sedangkan Deck E menggunakan 19 nozzle dengan debit 342 L/menit. Pada interval analisis 0 sampai 2000 detik, seluruh modul aktif pada 187,887 detik di Deck D dan 11,611 detik di Deck E. Heat release rate maksimum mencapai 6141,41 kW di Deck D dan 7154,28 kW di Deck E, dengan pelepasan panas terintegrasi masing masing sebesar 7712,72 MJ dan 7925,62 MJ. Temperatur modul tertinggi mencapai 1039,12 °C dan 1064,56 °C. Pada Deck E, paparan temperatur gas lokal tertinggi terjadi di atas battery pack, dengan THCP E1 mencapai 1010,95 °C, sedangkan titik pengamatan lainnya mencatat pemanasan transien yang lebih rendah namun tetap signifikan. Hasil penelitian menunjukkan bahwa geometri geladak, propagasi baterai, posisi sensor, dan susunan water curtain memengaruhi kondisi kebakaran yang diprediksi.

The carriage of electric vehicles on Ro-Ro ships requires careful fire safety assessment because a lithium-ion battery fire can sustain intense local heating, generate smoke, and reduce visibility within a vehicle deck. This study compares Fire Dynamics Simulator models of an electric vehicle fire on Deck D and Deck E of KM Dharma Kencana V. Both scenarios use the same vehicle geometry, nine module battery arrangement, material definitions, temperature controlled propagation method, and nominal Cartesian cell resolution. Module 5 is defined as the initial source, while the remaining modules activate when their local temperature reaches 120 °C. The water curtain activates at 180.043 s on Deck D and 180.033 s on Deck E. Deck D uses 18 nozzles with a nominal total discharge of 324 L/min, whereas Deck E uses 19 nozzles with 342 L/min. Within the common 0 to 2000 s interval, all modules are active by 187.887 s on Deck D and by 11.611 s on Deck E. The peak heat release rate is 6141.41 kW on Deck D and 7154.28 kW on Deck E, while the corresponding integrated heat releases are 7712.72 MJ and 7925.62 MJ. The highest module temperatures are 1039.12 °C and 1064.56 °C, respectively. On Deck E, the greatest local gas temperature exposure occurs above the battery pack, where THCP E1 reaches 1010.95 °C, while the surrounding observation points record lower but still substantial transient heating. The findings show that deck geometry, battery propagation, sensor position, and water curtain arrangement influence the predicted fire environment.
