It is not the rule or requirement from any class society, but many operators in the offshore environment prefer to paint the following items even though they are non-pressure / non-hydrocarbon containing parts.

  • Acoustic Enclosure
  • Enclosure Ventilation: Inlet Filter Housing, Inlet and Outlet Silencers
  • All Necessary Ductwork
  • Combustion Air Inlet: Inlet Air System
