Abstract

Terminal berperan penting dalam rantai pasok global sebagai fasilitas penghubung antara produksi dan konsumsi barang/kargo. Unplanned shutdown dapat menimbulkan konsekuensi yang signifikan, sehingga pemahaman akan risiko dalam terminal beserta potensi konsekuensi dari penghentiannya menjadi sangat penting. Faktor-faktor kegagalan sistem fasilitas dermaga yang mempengaruhi operasional lifting ditelusuri untuk menilai tingkat risiko terminal shutdown dan mencegah kegagalan kritikal. Metode Failure Mode and Effect Analysis digunakan untuk mengidentifikasi bahaya serta mengevaluasi risiko kegagalan beserta tingkat kekritisannya dengan analisis Pareto untuk analisis kekritisan, diikuti dengan metode Bayesian Network untuk analisis frekuensi yang dikombinasikan dengan tingkat konsekuensi dari FMEA sehingga kegagalan dapat dievaluasi dengan matriks risiko. Risiko teridentifikasi dapat dibagi dalam kategori risiko terhadap berthing-mooring, cargo transfer, IT ship-shore communication system, dan fire & safety system yang secara total menghasilkan 49 risiko kegagalan yang mengarah pada terminal shutdown. Frekuensi terjadinya bahaya teridentifikasi dalam rentang waktu dilakukannya 24 kali aktivitas lifting sepanjang satu tahun berada di level A atau tidak pernah terjadi di industri E&P. Peluang kegagalan IT & communication system, fire and safety system, mooring system, dan cargo transfer system adalah sebesar 0,000002; 0,000499; 0,027487; dan 0,08173 berdasarkan matriks risiko SKK Migas. Tingkat risiko terminal X shutdown berada pada area hijau menurut matriks risiko SKK Migas dan peluang terjadinya terminal shutdown adalah sebesar 0,00008488. Berdasarkan delapan risiko dengan tingkat risiko tertinggi pada matriks risiko, langkah mitigasi risiko terminal X shutdown mencakup opsi-opsi strategi mitigasi untuk penguatan komponen mooring system, penguatan koordinasi dengan lembaga setempat serta peningkatan sistem peringatan dini, penguatan kontrol pelaksanaan inspeksi dan pemeliharaan rutin struktur fender, penguatan sistem pengaman jaringan pipa, serta pemanfaatan sambungan fleksibel/hose dengan susunan prosedur kerja yang baik, peninjauan kembali spesifikasi teknis alat dan peningkatan standar pemeriksaan serta pengujian sesuai standar yang berlaku, penegakan prosedur pelatihan pengoperasian dan pemeliharaan alat, dan pengadaan program pelatihan simulasi situasi darurat dan upaya peningkatan keterampilan praktis dalam menangani situasi darurat.

Marine terminal plays a critical role in global supply chains as the connecting facility between the production and consumption of goods/cargo. Unplanned shutdowns can have significant consequences, hence understanding the risks in terminals and the potential consequences of shutdowns is critical. This study reviews the berth facility system failure factors that affect lifting operations to assess the risk level of terminal shutdown and develop risk mitigation options to prevent critical failures. The Failure Mode and Effect Analysis method is used to identify hazards and evaluate the risk of failure as well as the criticality using Pareto analysis for criticality analysis, followed by the Bayesian Network method to do frequency analysis combined with the consequence level from FMEA so that the risk of failures can be evaluated with risk matrix. The identified risks can be divided into the categories of berthing-mooring, cargo transfer, IT ship-shore communication system, and fire & safety system, resulting in 49 failure risks that lead to terminal shutdown. The frequency of occurrence of identified hazards for a period of 24 lifting processes in a year is at level A, meaning it never occurs in the E&P industry. The failure probability of IT & communication system, fire and safety system, mooring system, and cargo transfer system are 0,000002; 0,000499; 0,027487; and 0,08173 according to SKK Migas risk matrix. The risk level of terminal X shutdown is in the green area according to the SKK Migas risk matrix and the chance of terminal shutdown occurring is 0,00008488. Based on the eight risks with the highest risk level in the risk matrix, risk mitigation measures include mitigation strategy options for strengthening mooring system components, strengthening coordination with local agencies and improving early warning systems, strengthening control over the implementation of routine inspections and maintenance of fender structures, strengthening pipeline safety systems, and utilizing flexible/hose connections with a good arrangement of work procedures, reviewing equipment technical specifications and improving inspection and testing standards according to applicable standards, enforcing equipment operation and maintenance training procedures, and providing emergency situation simulation training programs and efforts to improve practical skills in handling emergency situations.
