The Effect of Use of Unconventional Power Generation Systems on the Safety of Navigation

Abstract

By using a hybrid system formed from two unconventional energy devices large vertical wind turbines and FLETTNER Balloon and a conventional source of energy, ship owners can save a great deal of fuel, thus making substantial savings and not least, reducing pollution, making environmentally friendly ships. Unfortunately, the legislation in force does not allow ships to enter ports with unconventional energy sources. For this reason, unconventional energy sources will be used only during transoceanic crossings or during longer journeys. In this article major points are: 1) the influence of the FLETTNER helium Balloon on the manoeuvrability and road stability of the ship; 2) the influence of large Vertical wind turbines installed on the deck of the container ship on the manoeuvrability and road stability of the ship; 3) the calculation of the stability of the ship with the FLETTNER Balloon with helium coupled and with the 4 Vertical wind turbines installed on the ship's deck; 4) modelling the phenomena regarding the comparative analysis of the forces in the FLETTNER Balloon and in the large Vertical wind turbines. As results were obtained: 1) velocity and pressure distributions, forces and kinetic energies for the FLETTNER Balloon in various weather conditions, with winds of 10 and 20 m / s respectively from different directions: 00, 300, 600, 900 in various planes; 2) the distributions of speeds and pressures, forces and kinetic energies studied individually for each of the four large vertical wind turbines at winds of 10 m/s and 20 m/s respectively in various planes, segregated according to the position of port bow, starboard and stern port, starboard. This development was due to the growing demands to solve various problems at the industrial level, coming to the aid of many engineers who wanted an improvement in the equipment used, but did not have the financial support to perform experiments.
