Appendix 2 - Colour Code for Hoses Transferring Bulk Substances

 To avoid misunderstanding about the hoses to be used for transferring bulk substances to connection points on board the vessel and offshore installation, colour coding should be used. For the purpose of identification the hose terminations and connection points should be colour coded by use of a coloured band to mark the substance, and all offshore supply vessels and offshore installations should adopt a colour code as follows:

Substance Coloured Band
Potable water Blue
Drill water Green
Fuel Brown
Dry bulk Yellow: cement
  Orange: barite/bentonite
Dedicated base oil/oil based mud Black
Brine Optional
Methanol Optional
