A strict implementation of SOLAS Regulation XII/8. 3 would result in every bulk carrier built before 1 July 1999 being marked, but as this was not the intention of the regulation, IMO has published interpretations to be followed when determining if triangle marks are required. These are printed in Annex 2 of MGN 144.
Why do some bulk carriers not need to be marked, and where can you find out which ships require to be marked?
