Abstract:

Since 2014 the Research Institute of Concrete and Reinforced Concrete, named after A. Gvozdev of Research Center "Construction", provides scientific and technical support of construction of unique transport hub facilities and a Liquefied Natural Gas (LNG) plant with a capacity of 36,376.3 million pounds [16,5 million tons] per year on the source of the South Tambey field in the Yamal-Nenets National District.

The Institute has developed recipes for concrete of liquefied gas tank and underground structures, has controlled over the reinforcement, casting and care during the hardening of concrete structures. The newest equipment for the production, transportation and concreting of common and prestressed structures were implemented. Hypothetical leak of LNG from the reinforced tanks can result into unacceptable consequences. Due to complex interaction of the harsh climate conditions, intrinsic unstable geotechnical base and vulnerability of Arctic environment can escalate into cascade accident. In order to eliminate the major accidents or to minimize the consequences within the acceptable margins a multi-tier safety framework should be administrated and placed. The key findings from accumulated scientific and engineering experience are described as the practice-oriented cases.
