Abstract

Terminal LPG Semarang merupakan salah satu tempat distribusi LPG di Jawa Tengah yang bergerak di bidang P3 yaitu Penerimaan, Penimbunan dan Penyaluran LPG. Dalam pengoperasiannya, terminal LPG Semarang sangat berpotensi menimbulkan bahaya yang bisa ditimbulkan, seperti kebakaran. Untuk menanggulanginya, Terminal LPG Semarang terdapat instalasi jalur pemadam kebakaran. Instalasi tersebut menggunakan empat pompa dengan kapasitas masing-masing yaitu 3.000 GPM. Dalam menjalankan hal tersebut, belum adanya perhitungan nilai kapasitas aliran air yang keluar pada setiap nozzle telah sesuai standar atau tidak. Pada National Fire Protetion Association (NFPA) 14 diatur megenai Standard for the Installation of Standpipe and Hose Systems. Regulasi tersebut mengatur nilai minimum kapasitas aliran pada setiap pipa tegak yang terhubung dengan nozzle. Oleh karena itu, untuk mengetahui telah memenuhi standard tersebut perlu menganalisis desain sistem instalasi perpipaan dan kebutuhan setiap nozzle dengan menggunakan simulasi Computational Fluid Dinamic (CFD). Simulasi CFD yang digunakan yaitu Software Pipe Flow Expert dan Ansys. Hasil simulasi menunjukkan bahwa desain telah memenuhi standard NFPA 14 dimana nilai kapasitas aliran terkecil terdapat pada pipa SP1 120 yaitu sebesar 500,87 GPM dengan head setiap pompa yaitu 73,14 m. Karakteristik aliran pada salah satu nozzle yaitu fixed water canon didapatkan kecepatan rata-rata yaitu sebesar 23,04 m/s dan kecepatan maksimum bisa mencapai 32,6 m/s dengan sifat aliran turbulen. Tekanan outlet simulasi sebesar 6,9 bar sesuai dengan kebutuhan pemadam kebakaran untuk mencapai tinggi tangki timbun yaitu sebesar 16,84 meter.

Terminal LPG Semarang is one of the LPG distribution places in Central Java which is engaged in Receiving, Storage, and Distribution of LPG. During the operation process, Terminal LPG Semarang has the potential to cause hazards, such as fire hazards. To overcome this potential, Terminal LPG Semarang has a fire extinguisher installation. The installation uses four pumps with a capacity of 3000 GPM for each pump. But until now, the calculation of the water flow capacity that comes out of each nozzle is still a question regarding compliance with standards. The National Fire Protection Association (NFPA) 14 regulates the Standard for the Installation of Standpipe and Hose Systems. The regulation regulates the minimum value of flow capacity for each standpipe connected to the nozzle. To find out that it has met these standards, it is necessary to analyze the design of the piping installation system and the needs of each nozzle using Computational Fluid Dynamic (CFD) simulations. The CFD simulation used is Pipe Flow Expert and Ansys Software. The simulation results show that the design meets NFPA 14 standards. The smallest flow capacity value is found in the SP1 120 pipe of 500.87 GPM with a pump head of 73.14 meters for each pump. The flow characteristics of one of the nozzles (fixed water canon) obtained an average speed of 23.04 m/s and a maximum speed of 32.6 m/s with turbulent flow properties. The simulated outlet pressure is 6.9 bar according to the needs of the firefighters to reach the storage tank height of 16.84 meters.
