Abstract
The paper gives an assessment of technical and economic capabilities of natural gas transportation by sea, allowing for modern gas carrier design, conditions of their loading and unloading and itinerary. Prospects for application of container version of gas transportation into Ukraine are shown. Preparation period before start of gas supply is shortened to 6 months, as manufacture of light-weight car cylinders and gas pipes has already been mastered in Ukraine. Furtheron, it is recommended to envisage construction and application of specialized gas carriers fitted with long metal-plastic cylinders, which are comparable with short pipelines, that allows reducing the strength margin to 1.75. As a result, cylinder metal content is reduced, and volume of transported gas is increased. Application of high-strength steels of 30KhGSA type to develop such cylinders is promising. 22 Ref., 5 Tables, 7 Figures.
 
 
Keywords: sea transportation of natural gas, metal-plastic cylinders, long cylinders, high-strength steels, welding with higher heating rate, activating fluxes, economic indices
