Nitrogen gas is used essentially during blanket applications when the hazardous materials carried by tankers are stored.

Blanket
For blanket applications, the air inside the warehouses is removed and the environment is turned into an inert state with nitrogen gas. Nitrogen blankets are indispensable for fuels such as chemical substances, LNG-LPG which are flammable.

Sweeping, Scraping
Maritime industry prefers nitrogen gas also for the cleaning and transportation of fluids such as oils.
