Abstract

Increased global energy demand has resulted in rapid growth in the oil and gas industry, including in Indonesia. Storage tanks play an important role in the storage of large quantities of liquids and must comply with strict technical standards and government regulations, such as American Petroleum Institute (API) 650, 653, and 575 and Permen of ESDM No. 32 of 2021. Seram Peaker 20 MW Masohi-Maluku Tengah MHP, as a vital asset for providing electrical energy, has a fuel storage tank that has never been inspected since the beginning of its operation. Non-compliance with API 653 standards potentially poses a risk of structural damage, leakage, and disruption to fuel supply. This research identifies the importance of periodic structural integrity evaluation using an Ultrasonic Thickness Gauge GM 100 to measure the decrease in plate thickness due to corrosion and predict the remaining service life of the tank. The results of the calculation show that each course starting from course 1-5 is 109.4 years, 72.3 years, 56.9 years, 43.6 years, 38 years, this shows that the Daily Storage Tank PLTMG Seram Peaker 20 MW Masohi-Central Maluku can operate for the next 38 years.

Abstract

Storage tanks, also commonly referred to as storage tanks, are one of the units or pieces of equipment used to store fuel. One industry that uses this equipment is the Namlea PLTD located in Buru Regency. The type used is a Fixed Cone Roof Tank to accommodate fuel that will be supplied to the power plant engine (Diesel Engine). The service life of the tank is ± 5 years, but based on field observations, it appears that there is corrosion on the surface of the tank, which is quite fast. Concerning that, the purpose of this study is to calculate the corrosion rate and corrosion hazard during the general period of use. The method used in data collection is field observation by measuring plate thickness using an Ultrasonic Thickness Gauge. Furthermore, the measurement results were analyzed using the API 563 standard to calculate the corrosion rate. The results showed that the corrosion rate on the tank blanket (shell) at the first level was 0.9 mm/year, the second level was 0.6 mm/year, the third level was 0.88 mm/year, the fourth level was 0.9 mm/year, and the fifth level was 0.85 mm/year. Then the remaining life for shell parts at the first level is 6 years, the second level is 7.6 years, the third level is 7.8 years, the fourth level is 7.9 years, and the fifth level is 9 years. The results of data processing indicate that the 300 KL diesel tank remains feasible for operation in Namlea PLTD, Buru Regency. Keywords: Fixed Cone Roof Tank, standard, thickness, corrosion rate
