Abstract

The improvement of Ship Energy Efficiency has been a major issue for the Shipping industry, mainly for three reasons; primarily because the fuel expenses of merchant ships contribute dramatically to the overall vessel’s expenses, following the continuous increase of the bunker prices. Secondarily, the Conventional Diesel Engines and Gas Turbines emit great amounts of Greenhouse Gases (GHGs), contributing to the Climate Change. Thirdly, the last six years the shipping industry was characterized by a recession, followed with a decrease in revenues and a low interest for newbuildings. Consequently, the low income made crucial the need for lowering of costs and thus new technologies through EEDI. This gave the opportunity and the time frame to the Shipyards, to follow the new industry requirements, modify the standard designs and proceed with technical innovations. The objective of this Diploma Thesis is to contribute to the identification of methods and technologies for vessel’s construction in order to improve EEDI and for vessel’s optimal operation according to SEEMP. Initially, in the first chapter a brief introduction is made to the environmental issues raised, in relation with shipping industry and the legislation framework. Also will be presented and explained the two main indicators EEDI (for new-buildings and EEOI (for existing ships) proposed by the IMO. The second chapter describes the main technologies and techniques used, in order to improve the construction of a new-building for achieving a better EEDI. The third and fourth chapter is a presentation of the investments, modifications, management and operational changes that can be made in order to improve energy efficiency of existing ships, according to SEEMP. The fifth chapter is an effort to present an economic result of modifications made on an existing vessel and to quote the several parameters that should be taken into account by owner.
