Wait.
6 Ship cargo oil tank coating
6.1 The inner wall of the cargo oil tank and the cargo oil piping system of the carbon steel ship should be treated with corrosion protection.
6.2 The anti-corrosion coating should adopt epoxy resin coating with product qualification certificate and use permit, which is resistant to civil aviation fuel, dirt and corrosion.
Corrosive impurities, additives and other corrosion ability, and does not affect the physical and chemical properties of civil aviation fuel.
6.3 The coating of the inner wall of the cargo oil tank and the cargo oil piping system should be intact and covered completely. Any of the following should not occur.
a) The peeling area of a single point of the coating is greater than 100 cm2;

Rust, the grade should be St2.
7 Seaworthiness of newly built and repaired ships
7.1 For cargo oil tanks and cargo oil piping systems whose coating repair area accounts for more than 10% of their total area or for newly built ships, they should be installed with three jet fuels before loading
Carry light oil, and the most recent load should not be naphtha or gasoline.
7.2 Ships with cargo oil tanks and cargo oil piping systems whose coating repair area accounts for 5% to 10% of their total area should be loaded and removed before loading jet fuel.
Light oil products other than naphtha and gasoline.
