Abstract Rising demand for transportation safety during their operation has become public awareness these days which leads to massive development in navigation and mitigation technologies. However, accidents for various transportation modes, including ship, are still occurring despite this progress. The numbers of involved parameters make accidental phenomena in the maritime environment, namely collision to be the latest concern as its influence on remarkable casualties. This paper aims to analyze ship collision incident which involves cargo carrier and passenger vessel. Structural crashworthiness as the main subject accounting for accidental limit state design and safety assessment is performed using a finite element approach to observe both global and local behaviors of the target ship under the bow impact. Initial prediction indicates that major collision energy is dedicated to destroying the main deck and outer shell. The tendency of the force during the collision period explicitly hints that progressive failure on the deck will continue to take place even if the accidental limit is extended. The behavior of the local member/component of the target ship is also to be presented in the discussion. Keywords Ship collision · Deck–bow impact · Finite element analysis · Structural crashworthiness · Global failure contours · Local shell tendency
1 Introduction Ship as one of the preferred mass transportations for either passenger or cargo distribution has experienced continuous development since the beginning of the recorded human history. That time, the human who has an urge to communicate (including market trade) with his fellow on the separated islands invented this transportation mode. As modernization and advance engineering technology as initiated by the first industrial revolution, ships are categorized based on their Technical Editor: João Marciano Laredo dos Reis. * Aditya Rio Prabowo [email protected] 1

purpose and cargo; for example, research vessel is designed to make research activity that can be carried out in maritime environment, and oil tanker is addressed to carry crude oil and similar products. Within this evolution range, navigational instrument has also affected regulation that radar, sonar and others are mandatory as part of active safety effort [1, 2] . During their operations, the ships tend to face many kinds of experienced load, and
