FPSO Fan drive apparatus and method for FPSO turret ventilation system

摘要

According to an aspect of the present invention, there is provided an apparatus for driving an air supply fan of a FPSO turret ventilation system, the apparatus comprising: a toroidal support (10) forming a path of an air flow annularly; An air supply unit 20 including a main air supply fan 21 and a sub air supply fan 22 that are connected to one side of the annular mount 10 via a damper and are independently driven; An exhaust means 30 connected to the other side of the annular belt 10 via a damper and having a main exhaust fan 31 and a sub exhaust fan 32 driven independently; And control means (40) for varying the amount of air supply and exhaust flowing into the path of the annular platform (10) under a predetermined condition.Accordingly, the operation of the second exhaust fan and the damper is determined by detecting the intake air or the internal gas in the FPSO turret annular region, thereby optimizing the ventilation system by reducing the duct size and the fan capacity.;
