The degassing process on ships involves removing the hazardous cargo vapor that forms in the remaining 10%-15% space after removing 85%-90% of the cargo tanks. The risk of explosion and burning caused by this vapor is of great importance, especially in ships carrying dangerous cargo such as oil and chemical tankers.
Various methods are used for the gas free process:
Ventilation through the Circuit: In this method, ventilation is provided through the filling and discharge circuit connected to the cargo tanks. Air is introduced into the tank using an air source connected to the main manifold and the vapor in the tank is discharged to the outside. Ventilation with Air Pipes (Manika): In this method, ventilation is provided by hanging special air pipes into the tank. While the steam in the tank is being expelled, it is important to position the air inlet to receive wind.
During the gas free process, appropriate weather conditions must be ensured and monitored carefully. In this way, the process can be carried out efficiently and safely.
