Optimization Calculation on Maneuverability Index of Small Scale Ship Model

A rating based fuzzy analytic network process (F-ANP) model for evaluation of ship maneuverability

In this paper, a novel rating based fuzzy analytic network process (F-ANP) model is proposed for the evaluation of ship maneuverability and the improvement of maneuverability standards. By incorporating the F-ANP technique into the American Bureau of Shipping (ABS) maneuverability standards, the proposed model is able to solve the problem of mutual dependencies of the maneuvering factors inhere...

The Study on Maneuverability of Electric Propulsion All-Direction Vector Thrusting Ship Using Rudder Propeller

This paper studied the maneuverability of the pure electric propulsion all-direction vector thrusting ship called “Century myth”, which also is the first one of its kind in inland rivers in China. Abilities such as turning, stop, changing of course and course keeping are studied. The main research method is by test and comparison, the result shows that the maneuverability of this kind of ship i...

Ship Trim Optimization for the Reduction of Fuel Consumption

Greenhouse gas emissions and atmospheric pollutants, economic savings, as well as alignment with the new rules of the shipping industry's leading is a new concern. In order to meet and achieve these goals, many efforts have been made. In this paper, some methods for reducing fuel consumption, including optimization of floating trim, have been considered in design draught. In this regard, the bo...
