Ventilation system design and research on column and pontoon of tension leg platform

 Combined with a first front-end engineering design in China, studies the ventilation system for column and pontoon of tension leg platform. Analyses the system design principle including design premise of ventilation system, hazard area division, ventilation type selection, ventilation rate calculation, and the operation mode, clarifies the ventilation system design requirements for all kinds of tanks and main design points of air duct, and forms a complete ventilation system design method for column and pontoon of tension leg platform.
