This study aims to analyze the risk on subsea pipeline of PT. AZ affected by the PT. XY refinery reclamation project located on West Java Coastal. Using the DNVGL-RP-F107 subsea pipeline protection risk assessment, the study pays attention to the identified Major Accident Event, i.e., dropped anchor and soil excavation. The object of this research is focused on the 12 diameter subsea pipeline from GG A to OPF (Onshore Processing Facilities) with 2 meters burial depth from KP 24.6 to KP 34,713 near the 280 Ha refinery reclamation area. This study uses secondary data covering the characteristics and properties of the subsea pipeline, the passage ships/tugboat and deployed anchors, and the soil excavation activity. The approach used is quantitative descriptive analytic which prioritizes in-depth analysis. The results shows that the consequence of dropped anchor is with pipe damage level of D1 which means that no additional safeguard is needed to further reduce the residual risk. On soil excavation risk assessment, the initial risk value generated is 9 (medium) with pipe damage level of D3, therefore some additional safeguards recommended so that the residual risk becoming Tolerable (ALARP). Some additional advises are provide to ensure post-project operational safety
This thesis was looking for compliance for the implementation of oil spill response in PT. Z, especially for the oil spill response procedure (OSCP) element, conformity with standard of the Indonesian government regulation, Ministry of Sea Transportation No.58, 2013 related oil spill response at waters and port, SKKMigas PTK-005, 2018 related management of health, safety and environmental protection in upstream oil and gas activities and international standard, IPIECA-IOGP, 2019 related oil spill preparedness and response: an introduction, IPIECA-IOGP 2015 related contingency planning for oil spills on water and research used assessment tool from Naational Fire Protection Association ( NFPA) 1600 edition 2013. The research was qualitative descriptive method. Based on reseach, PT. Z oil spill response procude (OSCP) was comply with Indonesian government regulation and international standar. In addition, PT. Z has emergency response team, oil spill response personnel, oil spill response equipment, and oil spill response exercise program.
This thesis discuss about explosion risk analysis from chemical material at PT Z, the studyis focusing on Vapour Cloud Explosion (VCE) that caused from four spherical tank pipingrelease. The analysis using 3D Computational Fluid Dynamic approach with FLACSSoftware. The methods that used on this study is qualitative with descriptive design andusing QRA Method to analyzing explosion risk at PT Z. the result from this study is anexplosion incident, generated a blastwave that can be damage to structure building likeoffice building, warehouse, and other building outside PT Z Facilities. A blastwave alsocan damage human body. The power of blastwave affect by some factors like geometry,Combustible Material, Confinement, and Environment condition. The maximum pressurefrom several monitor point is about 4 Psi. The recommendation to PT Z is always tomaintaining their equipment, tools, and facilities like tank and pipe. Also they must doroutines audit for explosion preventive.Kata kunci:FLACS, EXPLOSION, VCE, LPG, QRA.
Fire accident of crude oil tank is one of major accident event resulting in fatality. A large scale of flammable crude oil tanks is operated by Company Z. This research is a quantitative risk assessment of fire accident on crude oil tank where the risk is defined by measurement of frequency and consequence. Event frequency is calculated based on event tree analysis result of fire accident on tank storage. The fire consequence and its impact to personnel working in control room is measured by using ALOHA software. A flammable crude oil is stored in a fixed cone roof tank located 70 meter from the control room. Major accident events which potentially occur in the facility are pool fire and vapor cloud explosion. Pool fire has significant impact to personnel working in control room based on consequence modelling. Both individual risk and societal risk are assessed based on possible failure scenarios. The risk assessment result of pool fire consequence to personnel within the facility is still within tolerable limit. A consistent implementation of risk control include process safety management should be maintained to ensure risk is always within tolerable risk
Accidents in the construction field higher than other industrial sectors. Canes accounted for 38%share of fatal accident there in the industry. Therefore, this study discusses about risk assessmentof occupational health and safety risks in the work of lifting the transport of materials using towercranes in construction projects Apartment XY by PT. X 2014. The purpose of this study was todetermine the priority of safety and health risks that require risk control in the process of liftingjobs transport material use tower cranes. Methods This study uses an observational study design,and for risk analysis using semi-quantitative methods. The results of this study are at risk there are10 basic events were included to the category of very high, there are 7 events were included intothe category of priority 1, there are 6 events were included into the category of subtancial, andthere are 8 events were include into the category of priority 3. In the existing risk, control hasbeen done by companies can to reduce risk. There are nothing task were include into the categoryof very high, there are 2 events in the category of priority 1, there are 6 events were include intothe category of subtancial, there are 19 events were included into the category of priority 3, andthere are 4 events were include into the category of acceptable. In the predictive risk, there are 27events that enter into the acceptable category, and 4 events are still in the category of priority 3 andrequires further attention. Advice can be given to this research is needed for a more optimalcontrol of the K3 and needed for the addition of PPE for all workers in the company.Keywords: Risk assessment, tower crane
