At the moment gasification using natural gas is the most profitable in terms of energy, efficiency and ecology as well as energy source availability. In conditions of absence or workload of cross-country gas pipelines, rugged geological reliefs, absence of the possibility to lay new gas pipelines gasification using liquefied natural gas (LNG) is the most effective method.

However by now the basic standards for designing systems using liquefied natural gas (LNG) are off-market and unharmonized with the requirements of Technical regulation law and Technical regulations for fire safety requirements.

Development of LNG medium-capacity production is constrained by absence of clear fire safety requirements. Therefore a large variety of special technical specifications (STS) should be developed. STS development for medium- and low-capacity projects is often comparable with the cost of design works and the duration of development is approval by the state authorities is often the reason for making a decision on refusal from the project implementation.

With all difficulties of designing, insufficiency and conflicts in regulatory documentation it should be noted that 4 LNG production plants and 11 LNG consumption systems have been built and operate in the Leningrad region. Works on construction of these projects commenced in the beginning of 1990-ies and the first of them were implemented in 1995. These projects demonstrate high level of environmental compatibility and energy efficiency.

Considering advantages of LNG use in comparison with propane-butane and particularly with diesel fuel the importance of reworking the existing general rules and development of new ones both for LNG production and storage systems and for LNG consumption projects should be noted. It will allow expediting and developing such promising direction as natural gas liquefaction more effectively.
