Analisa Risiko Material Pipa Penyangga Jembatan PCK-03-A Pada Pengeboran Minyak di PT. X Menggunakan Metoda Risk Based Maintenance

Abstract

The support pipe is an important part of the bridge, because it is the basis for the bridge to stand upright. If there is a problem, it will have an impact that will disrupt the transportation of oil drilling, causing losses to the company. Therefore, a method needs to be done to maintain the bridge in order to minimize various possibilities that may occur, which is the method of implementing preventive actions in the form of maintenance. In maintenance there are also various techniques that can be used, one of which is the Risk Based Maintenance (RBM) method. This study uses this method to determine the remaining life of bridge support pipes from steel pile sections. By looking at the calculated risk ranking method, it was found that the support pipe is included in the significant (low) risk category for piles with code 9C. The RK value is a function X of the corrosion risk and a function y of the thickness (t) of each pile which amounts to 3 based on the data. Where the determining coefficient is one or 100% of the influence of the pile thickness is affected by the corrosion rate, where the corrosion is higher, the pile thickness is thinner. Both problems have a very high correlation between the risk of rust and the thinness of each pile because the correlation coefficient is 1 (one). The higher the corrosion rate risk value, the less the remaining service life of the bridge, especially for the support pipes, so the maintenance strategy must be considered, especially for the piles that have the most critical corrosion rate values ​​of the three samples study on PCK-03-A bridge.
