Análise da ventilação de praça de máquinas em navios, embarcações de apoio e unidades de perfuração

Abstract

The objective of this study is to describe the general mechanical ventilation system, characterizing air insufflation and exhaustion, inside a square of ships' machinery in the Brazilian coast or in industrial complexes. Adequate capacity, correct sizing, and good air quality, aim at a better performance of the equipment, human well-being need, better layout for the full utilization of the air flow through the enclosure, facilitating the increase of yield and economy of the whole industrial process. Much has evolved in the last decades, always focusing on the better performance of the energy plant, lower fuel consumption, greater air demand for alternative equipment, greater protection against local temperature, aiming mainly at positive pressure inside the enclosure, control temperature and humidity. Evolutions always focused on the interest of the owner and the customer, cargo owner or contractor. Today the great world policy is safety first of all, not only of the equipment, but especially that of the worker. Safeguarding human life represents an investment for the ship-owner, this also has to do with a good workplace, where thermal comfort, hearing and personal protection are very important objects of study and development. The control of heat and humidity is present in any modern vessel today; all with the aim of also improving the performance of operators, the main object of care these days. This is the purpose of the ventilation system, that is, to make the quality of life, in places inhospitable to the human, a reality.
