Berdasarkan MIL-STD-882D

Description Category Significance Catastrophic I Could result in death, permanen total disability Critical II Could result in permanent partial disability, injuries or occopational illness that may result in hospitalization of at least three personal Marginal III Could result in injury or occupation illness resulting in one or more lost work days. Negligible IV Could result in injury or illness not resulting in a lost work day Description Level Probability

Frequent A <10-1 Probable B 10-1 s/d 10-2 Occasional C 10-2 s/d 10-3 Remote D 10-3 s/d 10-6 Improbable E > 10-6

Safety Integrity Level Node : Truck LPG Liquid Loading Deviasi : High Pressure Consequence : Over pressure on pipe, skid tank, and leaked on TLA (Truck Loading arm) Dimodelkan dengan simulasi Shellfred

Hole Size Injury Massflow Rate (kg/s) 0.25 Inch no Skin demage 0.66 1 Inch First degree burn 10.61 Rupture Second degree burn 57.07

Hole Size 0.1 inch

Diambil skenario hole size 1 inch sehingga operator yang mengalami luka bakar akan berjumlah lebih dari 3 orang sehingga masuk dalam kategori II. Sehingga frekuensi dengan kategori C dan consekuensi kategori II menunjukkan level resiko Medium Risk .

* No release is condition where no LPG release on enviroment when overpressure

  • ccur

* No flame is condition where LPG release

  • n enviroment and not ignition (safe

dispertion) * Jet Fire is condition where LPG release on enviroment and ignition.

Kesimpulan

  • Berdasarkan analisa HAZOP terdapat Risk ranking ketegori

Medium High Risk 4 titik dan high risk 1 satu titik, keempat titik tersebut terdapat pada daerah filling shed.

  • Jika sistem mengalami over pressure, kemungkinan 3 skenario

kejadian yang mungkin akan terjadi meliputi no release dengan probability 3.69E-02, no-flame dengan probability 9.46E-03, dan Jet-fire dengan probability 2.43E-04.

  • Skenario berpeluang terjadinya jet fire sebesar 2.43E-04. Nilai

2.43E-04 masuk dalam kriteria SIL 3.

  • Peforma layer protection yang terdapat di filling shed sesuai

dengan yang di gunakan pada terminal LPG Zhuhai, Guandong, China yaitu SIL 3.

Review

  • Terminal

LPG bergerak di bidang jasa penerimaan, pencampuran, penimbunan, dan enyaluran LPG .

  • Kesalahan Operasi pada sebuah Terminal LPG akan

berdampak pada operasional dan operator.

  • Untuk mengatasi kesalahan Operasi, Terminal LPG Zhuhai,

Guandong,China menerapkan SIL-3.

  • Dari hasil analisa peforma layer protection yang terdapat di

filling shed Terminal LPG masuk dalam kriteria SIL 3 dengan nilai PFD 2.43E-04 .
