ABSTRACT
The study is devoted to improving reliability of diagnosing the technical condition of oil pumping units. The currently applied methods of diagnostics do not allow reliable determining defects, because the methods of non-destructive testing use indirect and expert methods of their identification. It is proposed to use an approach to determine the position of the defect according to strain gauges located on the supports of the unit. Knowing the location of the defect, together with information about the frequency and intensity of the defect oscillations, it can be identified with high reliability. The fundamentals of the calculation scheme and mathematical model, which allows determining the vertical and horizontal coordinates of the defect by analyzing the dynamic reactions on the supports and phase delays, are presented.
KEYWORDS: diagnostics, technical condition, tensometry, vibration analysis, oil pumping unit.

ABSTRACT
The results of researches on the determination of pipeline pumping parameters using the integrated model of the flow, previously described in [1,2], are given for pumping cases using the pumping station's pumps into the tank farm and pumping using mobile pumping stations into temporary barns and existing pipelines laid in one technological corridor with repaired area. Systems of equations for determining the pumping time in the specified cases are obtained. In particular, when pumping via mobile pumping units, the pressure of the unit is shown as a function of the drop in the filling level in the inclined section of the profile of the pipeline being emptied and on the back pressure in the existing pipeline to which the pumping is carried out. For the latter case, a system of equations has been obtained that allows us to accurately calculate the maximum allowable safe pumping flow rate, which excludes exceeding the allowed pressure levels in the pipeline to which injection is carried out. It is proposed to use calculated values of allowable pumping costs in the form of curves superimposed on summary schedules of operating modes in addition to pipeline profile lines, hydraulic slopes and bearing capacities, which will eliminate the risks of emergency situations associated with exceeding permissible pressure levels in the pipeline to which pumping is performedvolumes released using mobile pumping units.
KEYWORDS: pipeline, pipeline emptying, integrated flow model, pumping calculation, method, mobile pumping unit, pumping flow rate.

ABSTRACT
The work analyzes spherical tanks specifications and technical documentation. During the research process the absence of uniform requirements for volumes and pressure in spherical tanks, a uniform calculation procedure on durability and stability of a spherical tanks, basic racks, uniform requirements to designs and materials, design, installation and tests of spherical tanks were revealed. Currently, the technical capabilities of the manufacturers allow to create new sizes of spherical tanks, which were not provided by old the normative-technical documentation. In this regard, there is a necessity of development of the new uniform document, where questions of design, production, installation and test of spherical tanks, also taking into account increase in single capacity and determination of the main recommended sizes of spherical tanks would be considered.
KEYWORDS: spherical tank, spherical shell, standard technical documentation, tank design, tank installation, requirements to a metalwork.

ABSTRACT
The shut-off valves are an important element to the safe operation of a trunk oil pipeline. Actual problem of shut-off valves optimal placing on trunk oil pipeline is defined with respect to minimal oil spill during accidents and planning repair operations. The method of optimal placing is presented as a problem of nonlinear mathematical programming with limits and these limits are minimal distance between line valves. The solution of mathematical programming problem is given with the help of rigorous (alternance) parametric optimization method which is founded on special qualities ultimate solution. The approach of shut-off valves placing taking into account typical cases. The results of optimal linear block valves placing calculation are shown at typical site of trunk oil pipeline between two oil pumping stations.  
KEYWORDS: oil, trunk oil pipeline, shut-off valve, minimization of natural environment damage, parametric optimization, problem of  mathematical programming, alternance method.

ABSTRACT
Operation of heat-insulated in-field pipelines of the Yamburg gas field (Cenomanian horizons) in the winter season is discussed. The cases are reveal when there is no ice or hydrate operation regime inside the gas stream, nevertheless, ice or hydrate depositingsare possible at the internal wall of the pipeline. This is due to the above-ground laying pipelines and the very gas0gatheringinternal wall is below than the temperature gas stream of the temperature of ice or hydrate formation. It is shown, that the effect under consideration is exist primary at ambient temperatures below -20 °C, especially in the places of the pipeline where the thermal insulation has broken (damaged).The calculations of the stationary thickness of ice or hydrate layers are presented.
KEYWORDS: gas gathering pipelines of gas fields, thermobaric regime, gas hydrates, ice.

POWER LAW DISTRIBUTION OF VOLCANIC ERUPTIONS IN SIZE, A MECHANISM OF MAGMA ACCUMULATION IN THE EARTH'S LITHOSPHERE AND HAZARDS PREDICTION (P. 43-51)
Viktor V. Ivanov, Cand. Sci. (Geol.-Min.), Senior Researcher, Institute of Volcanology and Seismology Far East Division, Russian Academy of Sciences
ABSTRACT
The cumulative graphs of the probability distribution for duration of the activations (eruptions) at Klyuchevskoy and Karymsky volcanoes obey a power law. The graphs are approximated by two straight-line segments. At small and medium durations (from 1 day to 6 and 2 months) the tangent of slope angle of the repeatability graphs γ = 0.53 - 0.55  (γ < 1). 3) At more long activation duration, γ sharply increases by 1.6 -3 times, which probably indicates the presence of some ultimate eruption size for a given volcano or a gradual approach to such a size. An avalanche-like mechanism of magma accumulation when large floating magma-filed cracks absorb smaller overlying cracks in a permeable zone of the lithosphere is proposed.  This may drastically change the law of their distribution in size from the initial exponential or normal to the power law one. Interestingly, the distribution of Volcanic Explosivity Index (VEI) for the  Kamchatka volcanoes, on the one hand, and the seismic moment (M0) of strong earthquakes in Kamchatka, on the other hand, obey an exponential law with similar indexes of –γ = – 0.7 and –0.6, respectively. The frequency of occurrence of volcanic eruptions in Kamchatka in the range VEI = 2 – 5 is about 10% of the global one, which is quite a lot, since the length of the volcanic arc of Kamchatka is only about 2% of the sum of the lengths of all the volcanic arcs on Earth. The distribution of the ejected tephra (VT) for the eruptions of the volcanoes of the world and Kamchatka obeys the power law with close indexes of  –γ = – (0.7–0.75). In consumption of steady state volcanism the average intervals of occurrence of eruptions in Kamchatka is estimated as follows: every 15 years (VEI = 4), every 90 years (VEI = 5), every 350 years (VEI = 6, extrapolation) and every 1,400 years (VEI = 7, extrapolation).
KEYWORDS: Magma accumulation, floating magma-filled crack, probability distributions of eruptions in size, long–term forecasting.

ABSTRACT
This article is devoted to accidents in the transportation of oil through the seas and oceans. The most important emergency situations associated with tankers on the high seas and in coastal zones are considered. Such accidents are of particular importance for assessing the environmental risk of maritime transport of hydrocarbons, as well as the analysis of regulatory legal documents of the legislative framework of the Russian Federation on maritime transport covering all aspects of environmental offenses. Accidents are described by dates, briefly characterized. The relevance of the article is justified by the possible rapid development of deposits in the Arctic, wherepipelinesare problematic to use in main pipeline transporting, at the moment, and only the tanker fleet remains. The purpose of the article is to get acquainted with the experience of working with the transport of hydrocarbons by sea, in particular with disasters in the tanker fleet and the consequences of environmental disasters.    
KEYWORDS: accident, disaster, tanker, spill, hydrocarbons, oil, seabirds, dispersants, sea, ecology.
