The addition of FAME to diesel. This is basically not a challenge, provided that the FFA-% is not too high (but this is probably not allowed within the specifications). Fatty Acid Methyl Ester

This process is called transesterfication and is predominantly done to lower the viscosity. Tank Coating / V Ships / September 26 th, 2012
Chemical Resistance Often the main deciding factor when selecting a tank coating. Extensive exposure testing has been performed - comparison with bench mark product - wide range of curing conditions including varying post-curing - a long list of chemicals tested - cyclic testing
Adhesion, blisters, discolouration, etc have been evaluated

Chemical Resistance Required Certain owners active the SEA region are typically having the requirement out-bound: Palm Oil products, including Palm Fatty Acid Distillates in-bound: methyl alcohol ; MEG; Caustic Soda; pygas; luboil & others In case the cargo tanks are coated with Tankguard Special Ultra, there are no limitations from the coatings point of view.

Chemical Resistance Required Pre-wash after carriage of aggressive cargoes and bio-fuels: this can be accepted for all cargoes that require this pre-wash This includes executing pre-wash after carriage of methanol .
Note: the pre-wash procedure needs to be discussed.
Tank Coating / V Ships / September 26 th, 2012
Chemical Resistance Required In general in cargo tank coating, care regarding subsequent cargoes, since risk of: -
Cargo contamination
-
Negative effect of sequence of chemicals
But these risks are not applicable when back-2-back shipment. Hence, any cargo can be shipped back-2-back.
