Analysis on the hull girder ultimate strength of a bulk carrier using simplified method based on an incremental-iterative approach [PDF]

, 2008
The hull girder ultimate strength of a typical bulk carrier is analyzed using a simplified method based on an incremental-iterative approach. First, vertical bending moment is examined by seven different methods.

Direct prismatic coefficient variation to hull form surface

International Journal of Naval Architecture and Ocean Engineering
The initial ship design process aims to optimize the hull form to enhance ship efficiency. During this phase, hull form variations are executed based on a reference ship to meet shipowner requirements, such as altering the CP (prismatic coefficient) to ...
