New top-7 vessels wind projects and analysis of their practical possibilities for the transport fleet

Abstract

Abstract

The article deals with ship wind energy systems, namely the analysis of their best modern projects. It is shown, that wind energy is one of the main directions of development of alternative energy, which saves fuel resources and reduces greenhouse gas emissions. Ship wind energy is givena constant attention, because at the beginning of the last century the basis of the transport fleet was mast sailboats. However, in the last 60 years, sailing systems have not received significant application. The purpose of the study is to analyze the technical capabilities of modern ship sailing systems. The objectives of the study are as follows: to identify the best modern projects, to analyze their advantages and disadvantages and to assess the real possibilities of their widespread implementation in the modern transport fleet. The scientific novelty of the study is the justification of this analysis and its criteria and the development of recommendations for further creation of the best ship wind systems. The relevance and importance of this work is due to the fact, that the right direction of research and development avoids unproductive waste of time, intellectual and material resources. Research results. The analysis of the TOP-7 projects proposed by Captain Watson in Sea Shepherd Ocean ACTION Reports is taken as a basis. It is shown, that the main disadvantage of this work is the inattention to the shortcomings of ship wind systems, which are due to the wind rose on the route and during the flight. First of all, because the stable annual wind processes in the world's oceans in the tropics and subtropics have a speed of up to 5 m / s, and the ship's own speed during cargo delivery reaches 7… 10 m / s. Among other disadvantages are the main: the roll of the mast wind systems under the action of wind and the oscillation of the vessel during its gusts. On this basis, a new ranking of TOP-7 projects is proposed. General conclusions. Two systems are considered to be the most expedient: “Eco Marine Power Wind-Solar Ship” with side placement of sails and “Flettner Rotor Ship” with Flattener rotors, which realize the effect of Magnus for the movement of ships. Recommendations for their implementation are developed.
