The Effect of Port Growth on the Safety Index in Madura Strait

Abstract This research examines ship safety level in port development through environmental stress method, which involves assessing the safety level in current conditions and simulating the addition of new ports to enhance shipping efficiency. This method evaluates safety levels based on each ship’s COG degree and identifies obstacle characteristics. Analysis results are visualized using the perception safety index matrix. These findings determine the permissible speed tolerance for ships navigating the Madura Strait under current and planned conditions. As per sample, simulation will be using MV PIS Mahakam for this research. The simulation indicates that safety index in the existing condition or scenario X is at a Marginal level, with the highest value being 749. Furthermore, in planned scenario with addition of 2 new ports and combination of 2 ports which called scenario A, B, and C, safety index values are 749 thus all considered marginal. The maximum speed tolerance under planned conditions ranges from 1.5 – 1.6 knots for a 114m ship.
