Abstract
Surabaya West Access Channel (SWAC) is a shipping lane in the Madura Strait. This shipping lane has a very crowded ship traffic. In 2016, there are 62,091 ships sailing around SWAC. The number of these ships caused a lot of ship accidents, such as ship collisions and ship grounding. The shipwrecks caused by the ship's accident caused a new problem for ship traffic. These shipwreck will eventually cause the collision of ship and ship grounding. According to the KPLP (Kesatuan Penjaga Laut dan Pantai) there are 22 shipwrecks in SWAC. The frequencies of ship collision and ship grounding due to shipwrecks will be analyzed with IWRAP software and manual calculations. The results of each head-on, overtaking, and crossing collision are 6.99 · 10-3; 1.02 · 10-3; 7,768 · 10-3 for manual calculation, then 7.07 · 10-3; 9.04 · 10-4; 7,789 · 10-3 for IWRAP analysis. The frequencies of ship grounding of the ship for each powered grounding and drifting grounding are 6.1 · 10-3; 1.27 · 10-4 for manual calculation analysis, then 7,764 · 10-3; 1,196 · 10-4 for IWRAP analysis. The ship collision and ship grounding caused damage to the ship's structure. Ansys software is used to analyze this damage. The output of the analysis is the total deformation and equivalent stress. Total deformation is the total displacement of structures for all axes. Meanwhile, the equivalent stress is the total stress that hit the collision area. The maximum of total deformation of any ship collision and ship grounding are 5 x 10-2 m and 5.4 x 10-2 m. Therefore, the maximum of equivalent stress for each ship collision and ship grounding are 1.64 x 109 Pa and 6.78 x 109 Pa. The consequences of ship collision and ship grounding produce low deformation and high equivalent stress. Incidentally, ship accidents cause huge losses to the structure and safety of ships.
