Abstract

ABSTRACTThe Ambon Peaker Gas Power Plant (PLTMG Ambon Peaker) is an electrical infrastructure facility powered by gas turbines, located in Waai Village, Central Maluku Regency, Maluku Province. The fuel oil storage tank used by the Ambon Peaker since 2019 is situated directly near the coastline, making it very vulnerable to damage, particularly from corrosion on its metal plate walls. Therefore, maintenance is necessary to prevent any unwanted workplace accidents. This tank stores fuel oil. The author conducted calculations for minimum thickness and corrosion rate to determine the remaining lifespan of the tank. The results indicate that the critical point is located at course 1, with a remaining lifespan of 121 years. This can be influenced by various factors, such as environmental conditions and fluid characteristics. Tank maintenance also needs to be considered to ensure the tank's reliability, allowing it to operate longer and preventing the need for corrective maintenance. Keywords: storage tank, corrosion rate, wall thickness, remaining life.

Abstract

Design of PLTS is an effort to enhance the reliability of electrical power, electrification ratio, and utilization of renewable energy in the oil and gas industry. The availability of electricity is extremely urgent to meet the production process requirements, particularly for the motor-driven SRP pumping system. Currently, the industry relies on PLN and genset electricity for daily production activities. However, the design of a centralized PLTS system is expected to meet the SRP electricity needs in the oil and gas industry. The power grid in the oil and gas industry is obtained from PLN and genset. Therefore, the need for a power plant is evident. Related to the research previously discussed with the title “Design of Centralized PLTS as an Alternative Electricity Supply for Sucker Rod Pump” (Pinky Kartikasari, 2024), this study aims to determine the capacity of panels and batteries required for the development of a centralized PLTS in the oil and gas industry. The method used in this research is quantitative because it involves calculating the capacity of solar panels, daily energy needs, and numerical system analysis. The results show that the total energy requirement for SRP electricity supply is 264 kWh/day. The required capacity of panels is 106 kWp, with a total of 200 monocrystalline panels each with a capacity of 550 Wp. Additionally, there are 128 batteries with a capacity of 24V 200Ah. The inverter used is the PV1800 ECO Series 6.200W type, with 20 units in total. Keywords: PLTS (Solar Power Plant), SRP (Sucker Rod Pump), Oil and Gas Industry

Abstract

Corrosion resistance is the most important criterion in determining both the service life (remaining life) and operational reliability of equipment in the oil and gas industry. So it is very important to monitor the performance of every equipment in this industry. As with storage tanks, during long periods of operation and use, performance will likely decrease or could be said to experience thinning, thereby posing a danger to the thickness and remaining life of the ultrasonic thickness measuring instrument. differences in steel thickness data from the beginning and the thickness carried out by researchers. The data collected is also data that determines the minimum value for steel thickness in order to calculate the useful life of the media that will be examined by tanks that carry out measurements and maintenance using API 653 standards. Take measurements at several points 1. From the results of the analysis of the 100KL Tank located at PLTD HARUKU Using the UTG-90 Ultrasonic Thickness Gauge tool for plate thickness in August 2024, the results were that for Course 1 3.3, Course 2 3.4, Course 3 4.1, and Course 4 4.0 and the remaining tank life for each -Course 1, Course 2, Course 3 and Course 4 respectively are 11.26 years, 11.86 years, 32 years, 27.8 years1. The 100KL tank needs to undergo a Remaining Life Assessment (RLA) in 2028 and a regular tank inspection routine must be carried out to prevent leaks in the tank at least once every 4 years.
