Abstract
Krisis listrik di Bali merupakan masalah kompleks yang dipengaruhi oleh beberapa faktor. Selain keterbatasan pasokan listrik dari Jawa dan peningkatan beban listrik, kelangkaan solar serta terbatasnya sumber energi terbarukan dan lahan yang tersedia juga turut memengaruhi kondisi ini. Hal ini menjadi perhatian serius dalam pengembangan sumber energi yang berkelanjutan untuk memastikan pasokan listrik yang stabil di Bali. Energi alternatif ramah lingkungan yang bisa dijadikan pasokan listrik di Bali adalah (LNG). Hal tersebut juga sebagai bentuk upaya mendukung penggunaan energi bersih sebagai bentuk implementasi program untuk mencapai target net zero emission pada tahun 2060 dan juga sebagai penambahan pasokan listrik di Bali. Pertimbangan pemilihan lokasi Terminal LNG merupakan faktor penting dalam rencana pembangunan FSRU di Perairan Serangan. Pada penelitian ini dilakukan penentuan area lokasi pembangunan FSRU dengan mempertimbangkan lalu lintas kapal di alur pelayaran Benoa, bathimetri pada wilayah tersebut, dimensi FSRU peraturan daerah tentang Rencana Tata Ruang Wilayah Bali dan Peraturan Menteri. Kemudian dilakukan penilaian risiko kecelakaan kapal dengan FSRU dan risiko pipa bawah laut akibat lalu lintas kapal. Analisis frekuensi risiko kecelakaan kapal dilakukan dengan menggunakan IWRAP kemudian dilakukan perbandingan menggunakan metode CRASH. Analisis konsekuensi yang terjadi akibat drifting collision dilakukan dengan pemodelan menggunakan perangkat lunak ANSYS. Penilaian risiko pipa bawah laut dari FSRU menuju anjungan di darat dilakukan dengan menggunakan standar DNV-RP-F107. Hasil dari penelitian yang telah dilakukan adalah FSRU ditempatkan pada jarak 1354 m di luar alur pelayaran Benoa. Berdasarkan hasil IWRAP dan metode CRASH, frekuensi powered vessel dan drifting allision berada pada level remote berdasarkan indeks frekuensi dari IMO. Hasil representasi risiko untuk drifting allision untuk 3 variasi kecepatan, yaitu 0.565 m/s, 0.668 m/s dan 0.873 berada pada tingkat acceptable. Penilaian risiko pipa bawah laut akibat dropped anchor, dragged anchor dan ship sinking berada pada tingkat ALARP dan acceptable.

The electricity crisis in Bali is a complex issue influenced by several factors. In addition to the limited electricity supply from Java and the increasing electricity demand, the scarcity of diesel fuel, as well as the limited availability of renewable energy sources and land, also contribute to this situation. This has become a serious concern in the development of sustainable energy sources to ensure a stable electricity supply in Bali. An environmentally friendly alternative energy source that can be used for electricity supply in Bali is LNG. This also serves as an effort to support the use of clean energy in line with the program's goal to achieve net zero emissions by 2060, as well as to enhance the electricity supply in Bali. The selection of the LNG Terminal location is a crucial factor in the development plan of the FSRU in Serangan Waters. This study aims to determine the suitable area for the construction of the FSRU by considering ship traffic in the Benoa shipping lane, bathymetry of the area, FSRU dimensions, regional spatial planning regulations in Bali, and Ministerial Regulations. Furthermore, a risk assessment of ship collisions with the FSRU and the risk to the subsea pipeline due to ship traffic is conducted. The frequency analysis of ship collision risk is carried out using IWRAP, followed by a comparison using the CRASH method. The consequence analysis of drifting collision is modeled using ANSYS software. The risk assessment of the subsea pipeline from the FSRU to the onshore platform is conducted using the DNV-RP-F107 standard. The results of the study indicate that the FSRU should be placed 1354 meters outside the Benoa shipping lane. Based on the results of the IWRAP and CRASH methods, the frequency of powered vessel and drifting allision are at a remote level according to the IMO frequency index. The risk representation for drifting allision at three speed variations 0.565 m/s, 0.668 m/s, and 0.873 m/s are at an acceptable level. The risk assessment for the subsea pipeline due to dropped anchor, dragged anchor, and ship sinking is at ALARP and acceptable levels.
