Abstract

Indonesia, as a tropical country surrounded by water, faces serious corrosion problems due to high rainfall and the presence of seawater containing corrosive salts. Metal materials, especially in storage tanks in the oil and gas industry, are very susceptible to this damage, so they require special attention to maintain their integrity.To evaluate the condition of the tank, an inspection was carried out using the Non-Destructive Testing (NDT) method with an Ultrasonic Thickness Gauge according to API 653 and 575 standards. In the August 2024 measurement, the 100 kl tank showed good condition with varying thicknesses. However, the rooftop section, despite having the highest thickness, recorded a higher annual corrosion rate than other sections.Analysis shows that while the thickness of the material can extend the service life of the tank, the high corrosion rate has the potential to accelerate the failure. The Rooftop is estimated to have a remaining service life of 6.9 years, lower than the rest of the course. This confirms that corrosion management and monitoring are essential to maintain the integrity of the tank and prevent more serious failures. Keywords : Tank, Rooftop, Corrosion, Non-destructive testing

Abstract

The impact of the corrosion rate of diesel fuel pipes in PLTD HARUKU, DESA PELAUW. This study aims to see how much influence corrosion control has on the corrosion rate and remaining service life studied using an Ultrasonic Thickness Gauge. Measurements were carried out directly with an Ultrasonic Thickness Gauge. The measurement results showed that the highest corrosion rate was 0.0975 mmpy and the lowest was 0.0189. The remaining life of each pipe is determined by a formula that has been adjusted by the standard, with a higher corrosion rate causing a shorter pipe life, in the diesel fuel pipe the highest remaining service life of the IPA is 149 years due to the small corrosion rate while the pipe with the lowest service life is 25 years due to the high corrosion rate. Based on this analysis, the pipe is still feasible to operate. In conclusion, although there are variations in the corrosion rate, and the remaining service life of the pipe can still be operated safely. Keywords: Corrosion control, Corrosion, ultrasonic thickness gauge

Abstract

Polymer injection is an EOR method using a polymer solution to increase oil recovery by decreasing the oil-water mobility ratio by increasing the viscosity of the injection water. The purpose of this study was to analyze the effect of adding seaweed to xanthan gum polymer at various concentrations. The influence that is analyzed in this study is the viscosity test and the adsorption of the solution. From the research that has been carried out, it can be concluded that the best polymer viscosity is a polymer mixture of xanthan gum and seaweed, while based on the adsorption test, xanthan gum polymer is the best..
