Abstract
In the oil and gas industry, there is a pipeline system that is used to channel the results from upstream exploration to the receiving place. The pipeline can stretch both on land and at sea. The phenomenon that occurs due to hydrodynamic loads can cause the risk of deformation and fracture in the pipe. in the following cases, the subsea gas pipeline is the object of analysis. The analisys of on- bottom stability is PGN gas pipeline in Ujung Pangkah. In DNV RP F-109 there are three methods that can be used to calculate the on bottom stability of subsea pipelines. The method used is the absolute static lateral stability method because the method has the requirement that the pipeline force must be able to withstand the maximum force from hydrodynamic loads, also find the vertical stability. The result of vertical stability of PGN gas pipeline in zone I, zone II, zone III, zone IV, zone V, zone VI, zone VII, and zone VIII are same with value 1.5125 qualify the safety factor of lateral stability, ≥ 1.1. The lateral stability of PGN gas pipeline in shore is 3.782, zone I 4.048, zone II 3.315, zone III 3.36, zone IV 2.723, zone V 1.29, are qualify the safety factor of lateral stability, ≥ 1.1. Zone VI 0.941, zone VII 1.021, and zone VIII 1.059 are not qualify the safety factor of lateral stability, ≥ 1.1.
