Design And Research On The Engine Room Ventilation Of Jack Up Drilling Platform

The jack up drilling platform is an upper platform and a plurality of legs which can be lifted and used for the exploitation of offshore oil.China’s vast resources of the sea resources,the Bohai Sea and the South China Sea and other sea areas have a lot of oil.The study of the jack up drilling platform can improve the existing technical level,at the same time,it is also an important Part of the optimization design of the ventilation system.The cabin is Part of the offshore drilling platform for power equipment and auxiliary machinery operations and engine personnel for workplaces.The design of ventilation system is an important component of offshore drilling platform design.The ventilation of the nacelle is to provide a good working environment for the machinery and cabin personnel,and to establish and maintain suitable environmental conditions(temperature,air flow,cleanliness and air composition,etc.)in the cabin,the direct relationship between the ocean drilling platform can work normally.Firstly,the calculation of the ventilation volume of the engine room and the distribution of the air volume in the engine room are carried out through the calculation formula.This process is an important Part of the design of the ventilation system,Then,the calculation of the size of the duct and the resistance of the duct is determined,And then draw the ventilation schematic layout.Finally,the selection of the fan and the wind speed and resistance of the duct and the noise check.
