Forecasting Estimation of Thermal and Physical Effect of Normal Operation of Deep Water Gas Main on Environment

Results of studying the possible negative influence of exploitation of the Russia-Turkey deep water gas main on the Black Sea hydrology within the area of the gas main route are presented as well as those for the influence of the changeability of the sea water state on the gas main operation. The effect is considered of convection caused by heat release from the pipe surface on the bedding of the upper boundary of hydrogen sulfide within the water area of the gas main route both while the normal operation of the gas main and in case of the damage of the protective pipe layer as well. A simplified technique to calculate the convection-produced flow from the deep water gas main is given and approved.
