Abstract

The effect of piling is a problem that involves several components related to ground vibrations. The process begins with the vibration that occurs due to the collision between the hammer and the pile which is then continued to the ground as a result of the interaction between the soil and the pile. The vibrations on the ground are then transmitted to the surroundings and have an effect on surrounding structures, such as houses, buildings, bridges or industrial infrastructures. With regard to oil and gas infrastructures, it would be necessary to pay attention to their tight safety factors. Therefore, estimation of the effect of piling vibrations on the nearby oil and gas industry infrastructures would be vital. In connection with the ORF infrastructure expansion plan, this research will investigate the effect of piles on the installation of the existing infrastructures. A finite element (FE) model is created using the Plaxis software to then simulate the driving and vibration effects on the nearby piles. Results of this simulation are interpreted in the form of peak particle velocity (PPV) values, then compared with the standard PPV values that are permitted in the existing regulations. The results of PPV value of the simulation results is smaller than 50 mm/s which is allowable based on the regulations of Eurocode 3.
