The GOST R 8.615, in which the metrological requirements to Instrumentation at the oil well heads and license sites are formulated, is developed and approved. It is noted that the ubiquitous compulsory introduction of GOST R 8.615 requirements will be the first and important step In forming of the state system of control of production, treating and further selling of the recovered oil and petroleum gas practically along the full production chain - from oil well to commercial accounting units, including the consumption of oil and petroleum gas for own technological needs.

Value of negative temperature is the upmost attribute to define strength of permafrost soils and thus, their bearing capacity when using for pipeline foundations. As a consequence, transfer of soils from plastic frozen to solidly frozen state both ensures higher safety of installations at unexpected temperature variations of permafrost soils, and is more economically effective. Most efficient ones, as per freezing efficiency and ease of operation and economic feasibility, are self-regulating seasonal cooling devices (SCD) with close-ended convection of V/L heat transfer fluid (ammonia, carbon dioxide, Freon gas). Close-ended convection units of V/L heat transfer fluid are featured for high freezing efficiency, as phase transitions occur with absorption and release of big amount of heat (e.g, 1300 kJ/kg for ammonia). The article considers thermal interference issues of a hot pipeline with permafrost soils in conditions of thermostabilisation applying the single vertical SCD. Boundary conditions on the pipeline - soil border, SCD - soil, and air - soil are stated. Areas of soil freezing and thawing near the buried pipeline are defined. The finite-difference approximation of thermal conductivity 3D equation is compiled. The design strategy and its implementation to predict 3D temperature soil profile near the buried pipeline and SCD is obtained. The design strategy takes into account seasonal changes of temperature and number of precipitations on soil, soil inhomogeneity as per composition and thermophysical properties of permafrost soils.

The paper deals with some issues of designing replacement hydraulic parts for flow rates of 0.6 Qn and 0.7 Qn comprising a replacement impeller and a guide vanes fitted in the double volute standard pump with the purpose of enhancing its efficiency and reliability. High efficiency has been obtained in the pump equipped with the replacement hydraulic parts at the low NPSH required. © 2011 Published by Elsevier Ltd. Source

A complicated and unstructured data flow frequently appears in a complex project management. Data flow management, systematization and control could be organized by the project team using newly implemented tools or standard tools developed on a major software solutions base. Microsoft Project and other MS Office products, Business Intelligence systems, teamwork software, online project management applications could serve as such tools. The best results, assuming three classic project management limitations - time, budget, project scope - could be obtained by interaction synergy of applicable instruments including software. One of the possible complex project information management solutions was perfected during projects management in 2009-2013 by authors and their project teams. Source
