| Resumo: | This master's thesis aims to analyze the activity of the operators in a control room of the
processes of production on-shore petroleum, with a focus on sociotechnical restrictions that
interfere in the decision-making process and the actions of operators and therefore, the
strategies (individual and collective) to regulate and maintain the operator action required and
the safety of the system, together. The activity in focus involves the supervision and control of
the production of thousands of barrels of oil/day in a complex and dispersed production’s
structures built in an extension of 80 km. This operational framework highlights the
importance of this activity for the fulfilment of the targets local and corporate efficiency, good
management of the environment, health and safety of operators. This is an exploratory
research and in the field, which uses the methodology of Ergonomic Analysis of the Work,
composed of observational techniques and interactional, having as locus control room of the
processes of production on-shore oil of an oil company. The population of this research is
formed by operators in the control room of an Brazilian oil company. The results showed that
the supervisory activity and control of the superheated steam injection is an complex context,
demands greater attention, concentration, calculations, comparisons, trend analysis and
decision making. The activity is collectively constructed between the control room operator,
field operator and the supplier of steam. The research showed that the processes of
communication and collaboration between the control room , fields and support staff are the
key elements of this activity. The study shows that the operators have the autonomy and the
elements necessary for work; and that there is continuous investments to improve the
technology used and that the operators report sleep disturbances as a result of chronic
exposure to night work. The study contributed with proposals for transformation of this
activity: with regard to the installation of a area reserved for food in control room, the
update the screens of the supervisory current operating condition, the periodic visits by room
operators in the field, standardization of production reports, development assistance and
standardization of nomenclature of controlling stations steam systems, to improve the
conditions of realization of the activity, improve the quality of products produced by
operators and contribute to reduce the possibility of slips or shifts in the activity. |
