“…2. More information about the safety issues on the lifting barges and HLVs can be found in the works of Abdussamie et al (2018) and Tan et al (2018). It is worth mentioning that only the decommissioning hazards relating to the steel jacket structure is considered in this paper.…”

Decommissioning of offshore platforms is becoming increasingly popular. The removal of these heavy steel structures is characterised by high risks that may compromise personnel safety and loss of assets. The removal operation relies on dedicated barges and heavy lift vessels that may descent or capsize because of mechanical or structural failure. The knowledge of associated hazards is driven by experience and failure data are often obtained empirically through analogous operations, which further introduces uncertainty to the risk analysis. This paper proposes an integrated safety analysis approach for conducting decommissioning risk analysis of offshore installations. The approach incorporates hierarchical Bayesian analysis (HBA) with Bayesian network (BN) to assess the accident causations leading to futile decommissioning operation. First, the overall system failure of a lifting vessel was reviewed with emphasis on where safety issues arise. In addition, the failure data obtained from expert judgements were aggregated through statistical distribution based on HBA. The aggregated failure data are then used to conduct dynamic safety analysis using BN, to assess and evaluate the risks of offshore jacket removal operations. The accident model is illustrated with a case study from Brent Alpha decommissioning technical document to demonstrate the capability of incorporating HBA with BN to conduct risk analysis.

“…Although Abdussamie et al (2018) studied the offshore barges transportation problem with focus on hazard identification and fuzzy set theory, the work focused on semi-quantitative risk assessment. However, quantitative risk assessment capable of quantifying the risks of decommission in its entirety is necessary (Wang and Pedersen, 2007).…”

“…Based on the prob-lems above, PT. Pos Logistik Indonesia considers it necessary to implement risk management and carry out risk analysis on the Postal network business, especially operational risk analysis is the risk caused by failures in the company's internal systems, failures in the systems or technology used, failures in human resource management or failures caused by external factors of the company [3], [4] on the Manpower component (driver) by taking into account the root causes and causes and observing several potential risks and causes of risk.…”

“…[2]; further research aims to integrate risk management through a multitier risk management structure by examining every step of the risk management process at all levels of the organization [5]; The next research is a monitoring program for food safety hazards that is organized based on risk by developing a decision tree to rank chemical substances that may occur in food products [6]; and risk management research related to freight forwarding services, including HR management of business competition in freight forwarding services, delivery errors, damage to goods sent, theft or warehouse fire [7]. In addition, research related to operational risk assessment has been carried out on the offshore transportation system, by using the Hazard Identification (HAZID) technique this research can measure and assess the level of risk during offshore operations using a fuzzy logic model [4]. Research on ship systems is carried out to measure ship operational risks in ship safety, in this study an alternative dataset is used (actual failure scenarios from ships) [8].…”

PT. Indonesian logistics posts have cooperation in the postal network field, namely cooperation in sending goods or shipments at a certain time, a certain amount from one point to another in accordance with a warrant from the partner. Components of the postal network include Manpower, vehicles, postal operational control, and operational costs. This study aims to examine the problems and roots of problems that cause risk potential for the risk of postal network components, especially in the manpower component (driver), and know how high the impact of the risk. The research method used in this study is qualitative and semi-quantitative methods by conducting case studies. Data collection was carried out by interview/FGD, and the distribution of questionnaires. The results showed that the risk of manpower is at high and very high levels. The results of the study will provide recommendations to the manpower component (driver) in the form of risk mitigation and can be used by companies in managing operational risk on postal networks, especially in the manpower component (driver). Keywords: manpower; operational risk; postal network; risk mitigation. Abstrak: PT. Pos Logistik Indonesia memiliki kerjasama dalam bidang Jaringan Postal, yaitu kerjasama dalam mengirimkan barang atau kiriman pada waktu tertentu, jumlah tertentu dari satu titik ke titik lain sesuai dengan surat perintah dari mitra. Komponen pada jaringan Postal meliputi: Man Power, Kendaraan, Pengendalian Operasional Postal, dan Biaya Operasional. Penelitian ini bertujuan untuk mengkaji permasalahan dan akar masalah yang menimbulkan potensi kejadian risiko pada komponen Jaringan Postal khususnya pada komponen manpower (driver) dan mengetahui seberapa tinggi dampak risikonya. Metode penelitian yang digunakan dalam penelitian ini adalah metode kualitatif dan semi kuantitatif dengan melakukan studi kasus. Pengumpulan data dilakukan dengan cara wawancara/FGD, dan penyebaran kuesioner. Hasil penelitian menunjukan bahwa risiko pada manpower berada pada level high dan very high. Hasil penelitian akan memberikan rekomendasi terhadap komponen manpower (driver) berupa mitigasi risiko dan dapat digunakan perusahaan dalam pengelolaan risiko operasional pada jaringan Postal khususnya pada komponen manpower (driver). Kata kunci: jaringan postal; manpower; mitigasi risiko; risiko operasional.
