heal.abstract	The growing interest in echo friendly technologies, created the need of a powerful computational tool that would effortlessly give a first impression of the feasibility of such applications. The consistently increasing petroleum, and fossil fuels in general, rates have led the marine industry to look for and embrace more eco-friendly technologies for the powering of commercial vessels. The most important and more common one is the idea of an all-electric vessel, fully disconnected by the need to use fossil fuels. Moreover, the short distance routes in the Greek marine environment make the use of such applications ideal. Until nowadays there have been plenty studies in the field of all- electric conversion for the commercial vessels. In this thesis the creation of a powerful computational tool has been achieved, providing the user with the capability to make a time cost study to be a matter of minutes. The development of such a tool have been accomplished with the use of Visual Studio 2017 environment and was written in Visual Basic.net. The methodology used was created by Christos Bakirtzoglou in his thesis and will be shortly presented here. This methodology has been converted to fit the needs of programming writing. It was divided to parts including Basic Calculations, Financial Calculations and Emissions Calculations. These parts have been assigned to individual Classes, so that could be called form the main program at runtime. In the Basic Calculations class, the energy demand is calculated in respect of the time that is available for charging the batteries in each trip of the vessel. Furthermore, the batteries number, volume and total cost is given as a result, respectively to the charging time in each trip. In the Financial Calculations Class, the financial elements of the study are being calculated. These calculations have been divided in the installation cost of the batteries, the operational costs for the batteries and the old system, including the cost of electricity for charging and the cost of currently used fuel and the maintenance costs for the two systems. Resulting in the benefits calculations have as output the benefits of such conversion in respect of the system’s life. Conclusively in the Emissions calculation Class, the total mass and cost of emissions produced by the old system are calculated. Furthermore, in the last chapter the results of Christos Bakirtzoglou thesis are used to prove this development tool’s capabilities.	en
