Dear researchers,

I am conducting a research related to biofouling accumulation on several antifouling coatings to relate them with the added resistance occuring on ship hulls. With the aim of this, several coatings applied on both a ship hull and static immersion pannels. At the end of one year ship operation, accumulation on the static immersion pannels and ship hull will be compared.

For the static immersion pannel tests, 6 flat plates coated with 6 different coatings and immersed in a fishing port and regularly taken out to observe the accumulation on them. My problem is that whilst rating the coverage areas I want to make a comparison between 2 standards which are ASTM and NSTM.
