Numerous systems are available on ships, the pipelines are complex, and the tank ventilation and oil and gas recovery systems associated with the tanks are particularly important.
IBC regulations provide that the venting system of the cargo tank is divided into two forms, namely "open" and "controlled" venting systems.
The open ventilation system is suitable for the goods which are not easy to burn and explode due to the evaporated gas of the liquid and have no toxicity or less toxicity, and is only used for a few special chemical ships.
The controlled ventilation system is mainly used for carrying toxic, inflammable and explosive goods. About two-thirds of the chemical inventory listed in the IBC code should be supplied with a controlled ventilation system by providing a pressure vacuum valve in each cargo tank.
At the same time, for cargo chemical ships carrying toxic liquid substances and having an absolute pressure of the boil-off gas exceeding 101.3KPa at 37.8 ℃, a boil-off gas collection system should be provided for collecting the boil-off gas during loading and unloading operations and returning it to onshore processing.
