INCREASE OF INDICATORS OF SAFETY OF OBJECTS OF OIL PRODUCTION OF KHANTY-MANSI AUTONOMOUS AREA AT A STAGE OF IMPLEMENTATION OF PROJECT WORKS
One of leaders among subjects of the Russian Federation in a number of indicators, such as oil production, electricity generation, and also on industrial output is Khanty-Mansi Autonomous Area (Khanty-Mansi Autonomous Okrug-Yugra). Enormous stocks of energy and materials, create potential threat of life and to human health, environment. The problem of ensuring industrial and ecological safety on objects of the oil-extracting industry is extremely actual now.
Technical investigation of the reasons of accidents shows that wear of the equipment, corrosion, mechanical damages, construction marriage, violations by the operating and service organizations of requirements of the legislation in the field of industrial safety at all stages of life cycle of hazardous production facility became the main of them. Emergence of refusals, depressurization of pipelines, lead to accidents, are followed by emergency oil spills, the fires, explosions and destructions. Among the organizational reasons of accidents it should be noted the low-qualified organization of works, violation of regulations of repair work, an inefficiency of production control, absence or malfunction of means of antiemergency protection, the alarm system.
One of stages of actions for increase of safety is development of project documentation on arrangement of fields of Khanty-Mansi Autonomous Okrug-Yugra. At a design stage there is an opportunity to find the most rational solution which efficiency is estimated both in value terms, and in indicators of reliability, safety of the conceived ideas. Hence the need to provide qualified technical decisions in all phases and stages of development of project documentation.
In this paper, there are offered measures for increase of safety at design of arrangement of fields of Khanty-Mansi Autonomous Okrug-Yugra by the design organization JSC “RN-UfaNIPIneft”, actions for restriction of volume of an exit of liquid from the oil and gas combined pipeline in environment through an emergency gap, actions for protection of pipelines against corrosion are offered.
Simulation of air streams at oil transshipment complex in order to determine an optimal location for buildings and facilities
While operating any hazardous production facility there is a possibility of a failure or an incident which can bring serious harm to human health and life as well as to the environment. At the design stage already, all the manufacturing processes at hazardous production facilities must be considered as potentially dangerous in order to have a possibility to make appropriate corrections before starting construction. In case the buildings and facilities are located unsuccessfully, there can be areas of accumulation of harmful and hazardous substances in the air that makes the risk of serious aftermath increased. Simulation of air streams by means of modern software helps to detect dead zones. In the process of simulating hazardous processes at this hazardous production facility and by visualization of calculations in the FlowVision software, all cardinal direction air streams speeds were determined and dead zones were examined. In order to keep constant control over contaminants concentration and in accordance with the enforceable standards, the production area of open processing units at refineries must be equipped with automatic protection systems. Protection systems must be chosen in accordance with the production type and the process parameters, changing of which may result in an accident, considering all possible cases of emergency occurring when automatic control systems fail. One of the main functional parts of the system is a gas analyzer which measures strength of contaminant exposure. In accordance with TU-gas-86 “Specifications for installation of signalizes and gas analyzers”, a location scheme for CCC-903M stationary gas analyzers at the site is offered as a measure to improve safety at this facility.
