Study on Transverse Strength of the Deck-Container Ships Due to Laying All Containers on Deck

The strength of transversal structure of the ship has a great effect on the safety of the ship. Ships will experience conditions that affect the strength of the ship's structure. Deck-Container ships are the ships that all containers are loaded on deck such as MV. Khendaga Nusantara series ships. The transversal strength of the ships is loaded mainly by the weight of cargo laying on the deck. This research aims to determine the transverse strength of a deck-container ship due to all container loads on deck. The research was done by using finite element method through modeling transverse ship structure, the simulation is conducted by varying the amount and layout of containers on deck. The loads applied to the model are side loads, bottom loads, and deck loads according to BKI rules. The results show that the stress that occurred in the web frame was 140.63 N/mm2 due to the placement of the entire container on the deck (full loading). For ship structure response, a deformation of 2.86 mm occurred in the web frame area at maximum loading. Stress ratio that occurs in all ship’s structures does not exceed 1 in other words the working stress does not exceed the allowed stress according to BKI rules
