Seakeeping performance of a rounded hull catamaran in waves using CFD approach
Journal of Mechanical Engineering and Sciences, 2017 Prediction of the seakeeping performance of a ship in the earlier ship’s design step is necessary to ensure the safety of navigation during sailing. To accommodate such a demand, this research proposes to analyse the seakeeping performance of a rounded ...

Multi‐objective maritime vessel routing with safety considerations
International Transactions in Operational Research, Volume 34, Issue 1, Page 337-371, January 2027.Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 In order to investigate the fatigue behaviour of trimaran cross‐deck structural details, the spectral and simplified fatigue analysis approaches are proposed. In spectral fatigue approach, three‐dimensional (3D) linear potential flow theory and global FE analysis are used for wave loads and stress transfer functions calculation; the stochastic spectral
