Increasing the Strength and Reliability of the Jetty Pile Structure with the Application of Glass Fiber Reinforced Polymer

摘要

In oil distribution process, especially in archipelago countries like Indonesia, jetty is an essential tool in loading and unloading oil from and to tanker. The main problem in jetty structure with steel piling is its corrosion resistance. The deterioration of the jetty structure strength was caused by the piling depletion caused by corrosion. In this study, calculation and mechanical strength testing for Glass Fiber Reinforced Polymer (GFRP) were conducted. The study was then applied to Pertamina Tanjung Uban jetty to strengthen the piling, and increase in compression strength of up to 63.38% was observed. The increase of compression strength from the application of GFRP however, doesn't have a linear strengthening effect when applied for other applications.
