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.
The oil industry has a high risk, cases of emergencies such as oil spills and fires in oil storage tanks occur frequently and are classified as a major hazard. This emergency event can occur due to failure of the safety protection layers (SPL) installed in the oil storage tank. Tanks T-04, T-09, T-18 are oil storage tanks of PT. X which has the potential to experience this emergency event, for this reason, a study is carried out on the impact of hazardous chemical exposure and heat radiation from the T-04, T-09, T-18 tank fires on humans and surrounding facilities. The study method used was a cross-sectional study with a quantitative approach to analyze the impact of exposure to hazardous chemicals in the form of mercaptans and benzene and heat radiation caused by oil spills and tank fires T-04, T-09, T-18 on humans and surrounding facilities. This research was conducted through secondary data collection both at PT. X and literature studies without intervening in the research object. The data obtained is used to quantitatively determine the impact of exposure to hazardous chemicals and heat radiation using ALOHA (Areal Location of Hazardous Atmosphere) software. The results of the ALOHA simulation from the emergency incident of the oil spill showed that the exposure to mercaptans and benzene in the PPP North Highway area was 1.33 ppm and 379.68 ppm, causing discomfort, irritation and temporary effects for humans exposed to the area. Exposures in the South Highway PPP area of 0.142 ppm and 40.72 ppm did not have a health impact on humans exposed to the area. Exposure in the PPP Operator Room Area of 2.9 ppm mercaptan resulted in exposed humans experiencing discomfort, irritation and was temporary, exposure to benzene of 829.79 ppm resulted in adverse or serious health problems or impaired ability to escape for humans exposed in the area. Exposure in the PPP Office Area of 1.18 ppm and 338.45 ppm had an uncomfortable, irritating and temporary effect on humans in the area. ALOHA simulation results of tank fire incidents resulting in exposure to heat radiation in areas inhabited by humans, namely in the PPP North Highway Area, PPP Operator Room Area, PPP Office Area with an impact that can result in death if exposed to up to 60 seconds, as well as in the Highway Area South PPP has the impact of experiencing second degree burns if exposed to 60 seconds. Heat radiation from a burning tank also has the potential to cause a domino effect in the form of a tank fire around the burning tank due to receiving heat radiation of 15 kW/m2. Safety Protection Layers installed in PT. X is not sufficient so that oil spill and fire emergencies are still at a high risk level according to the risk matrix of PT. X is categorized as an unacceptable risk (Not Acceptable Risk). This study provides recommendations for adding Safety Protection Layers to the PT. X to reduce fire risk to an acceptable risk.
