Abstract

Evaluation of the performance of cargo oil stripping pumps on the Mt. Noni T ship is needed for smooth loading and unloading of avtur at PT Pertamina Prata Niaga Integrated Wayame Ambon. Pumps that operate continuously will experience a decrease in work. This can be caused by several factors, namely the age of the pump, and the level of roughness of the pipe that causes an increase in head loss. The purpose of this study is to evaluate the performance of cargo oil stripping pumps on the MT. Noni T. The method carried out in the study uses a quantitative method with 2 variables. The independent variable is the input power and output power of the pump while the bound variable is the efficiency of the pump. The data obtained consisted of primary data and secondary data. The methods used when collecting data are interview, observation, and documentation methods. The result of this study is that there is a decrease in pump efficiency which was initially 100% to 80% influenced by the life of the pump and its operating time. Suggestions that can be given are Conducting periodic inspections of the pump to prevent damage that may occur in the future and Conducting inspections of the pump drive motor so that the pump works properly.Keywords: Screw, pump, efficiency, tanker, Flow.

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
