Hydrodynamics Modelling for Dock Layout Planning in Fish Landing Port (PPI) Api-Api, East Kalimantan

Abstract

The issue of relocating the national capital city to Penajam Paser Utara is one of the reasons why the Fish Landing Port (PPI) Api-Api needs to be developed. The maritime and fisheries sector in East Kalimantan is also known to have huge potential in supporting the economy.  One of the facility that need to developed is the dock. The exisisting  dock is a simple wooden dock that is placed perpendicular to the beach and only able to serve small ships. Therefore it is necessary to plan a dock construction at PPI Api-Api so that the dock can serve larger fishing vessels. In this research, hydrodynamics modeling were carried out using Delft3d for three alternative dock layout designs, namely; jetty, wharf, and pier type, henceforth selected which is most suitable to be placed at PPI Api-Api. Based on the simulation results of hydrodynamic modeling, the current velocity around the jetty type is > 0.15 m/s, while in the wharf and pier type it ranges from 0.05-0.15 m/s. Wave modeling shows the maximum wave heights that occur near the dock at the jetty, wharf and pier types are 0.9 m, 0.36 m, and 0.8 m, respectively. From the hydrodynamic modeling results, wharf type is the most feasible dock layout design to be selected.
