In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion

The proposed design methodology represents a new approach to optimize the propeller–hull system simultaneously. In this paper, two objective functions are considered, the first objective function is Lifetime Fuel Consumption (LFC) and the other one

Typically, ships are designed for calm water and a constant design speed. However, a ship experiences different speeds and sea conditions over her lifetime. Following the significant correlations between environment and ship behavior at sea, efforts

A ship is designed under inescapable uncertainty. Neglecting important uncertainties might lead to suboptimal designs. Furthermore, to achieve the best possible performance, the ship design should be optimized for the actual operational conditions, n

This study aimed at stabilizing and decreasing the fishing boat's nonlinear roll motion using a fin-roll stabilizer. To do so, numerical and analytical modeling have been introduced. In addition, a numerical method and empirical formulas for calculat

This paper is concerned with the problem of safely cargo transfer over a ramp between a cargo vessel and a lighter surface effect ship (SES). For this purpose, an adaptive neural network (NN) controller is proposed to control of ramp motions in the p
