Crashworthiness characteristic of longitudinal deck structures against identified accidental action in marine environment: a study case of ship–bow collision

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.

Mechanical and Microstructural Properties of A36 Marine Steel Subjected to Underwater Wet Welding

“…Recent work by Surojo et al [29] discussed the influence of the water flow and depth/location on welding performance using mechanical testing. Another possibility for extension of this work could involve marine vessels, e.g., the hull structure of a ship [30][31][32][33][34][35][36]. The subject is no longer on the material specimen scale, but the use of a down-scaled hull prototype or weld could be used to represent parts of the ship structure, such as the frame and side hull.…”

Design development and technical analysis of an auto checking hardness machine: A study case of the hardness tester HR-522 series

“…Material testing, calibration, and analysis are the essential processes in the material and structural characterizations of materials that are possibly subjected to various loads in technical applications [1][2][3][4][5][6][7]. The main material testing variable is hardness, which represents the resistance properties due to deformation and destruction.…”
