Pile Stability Analysis of Wharf in Container Port, West Java

The pier is a port structure that is used to close and moor ships when unloading cargo. As the ship anchors, it causes lateral forces subjected to the pier. This lateral force must be thoroughly analyzed as it is directly related to the feasibility, stability, and life design of the dock itself. This research aims to study the planning and stability of the pile structure of an going construction in West Java. The considerations to be analyzed include the lateral load of two types of ships (VLCC and ULCS) that affects the deflection of the pile structure as well as the pile diameter (60 cm, 80 cm, and 100 cm). The berthing force caused by these two ships towards different pile configurations is analyzed numerically with the finite element method (FEM) software. The analysis result indicates that a smaller pile deflection can be obtained if a large diameter pile is used.
