OPTIMIZATION OF PASSENGER VESSELS DIMENSIONAL MODERNIZATION TAKING INTO ACCOUNT THE ENERGY EFFICIENCY
Abstract
The environmental friendliness of any production is a modern requirement, which, among others, concerns the maritime shipping. The EEDI energy efficiency coefficient is an indicator that evaluates the ratio of the vessels’ negative impact to the environment and the vessel transport work. The current regulatory framework of the IMO in the field of international shipping is aimed at ensuring a gradual reduction of this indicator, what in the complex will ensure technologically possible minimization of the maritime shipping environmental impact. One of the directions for ensuring the permissible level of EEDI is modernization, including dimensional modernization, as a result of which the GT of the vessel increases, and this, in turn, increases the volume of vessel transport work and reduces the corresponding level of EEDI. The paper analyzes the energy efficiency of the world's leading cruise companies’ vessels for determination their modernization attractiveness. An optimization model for the passenger vessel dimensional modernization for the determination of the additional section length in the middle frame area of the ship is proposed, based on an integral consideration of the economic and ecological aspects of the vessel further operation. An experimental study of the model was carried out and substantiated its reliability and suitability for practical use in decision-making processes regarding the passenger vessels dimensional modernization.
