A retaining wall is among the common structures required in the coastal and port areas. This structure is constructed to support and protect elevated land near the coastline, e.g., coastal road embankments, or to develop port service areas, such as container yards, loading-unloading areas, etc. Despite its limited actual field implementation, a Parallel Concrete Panel Container type of wall structure is available. It has been promoted for its ease of construction in the coastal area, less use of concrete material, and less space occupation. The present study assessed the potential implementation of this structure as a retaining wall in coastal and port areas. In this study, the structural stability and strength analysis of the PCP is carried out for two types of tie rod configurations. The analysis was conducted using the numerical simulation software of PLAXIS 2D and SAP 2000. The results show that the container with a diagonal bonding configuration type A performs better overall structural efficiency than the one with a horizontal bonding configuration type B. The PLAXIS modeling results showed that PCP types A and B had safety factor values of 1.35 and 1.32, respectively. These values indicated that both structures worked stably. Additionally, it implies that the soil has sufficient strength to support the applied loads without failure.
