Abstract
The article contains the method of calculating the electric capacity by a non-self-propelled hydro power vessel which uses renewable tidal power to produce electricity. The vessel is built by means of reconstructing tankers that are in service or to be disposed and can be characterized as a power generating module of a floating non-self-propelled tidal power plant of continuous operation. To evaluate efficiency of the power generated module there has been worked out a method of calculating its generated energy, which allows for local energy potential of the tidal flow, structural characteristics of the module and its geographical position. Based on the developed method there has been given analysis of power generated by one electric power module which can be made by means of construction minor modifications of a standard tanker design. The calculation data obtained were analyzed in comparison with power capacity of small hydroelectric power plants operating in the north-west parts of Russia and with capacity of Kislogubskaya tidal power plant. The tidal power plants can generate electric power comparable with the capacities of tidal (marine) and river-type power plants. The economic benefit of the proposed power plant design is obtained due to significant reduction of costs for implementing floating tidal power plant, compared to the costs of the construction of tidal and hydroelectric stations. The floating tidal power plant is characterized by mobility and can be towed to any coastal zone where the tidal wave parameters are acceptable. When needed, capacity of the floating tidal power plant can be raised by means of attaching additional modules. Mounting and operating of tidal power plants are environmentally secure. The use of tidal power plants is a promising means of electrification for inaccessible and marginal coastal areas.
