For så vidt angår situationen, som den forventes at ville udvikle sig i perioden indtil 1990, kan der forudses et lettere fald i antallet af handelsfartøjer på over 100 BRT i verdenshandelsflåden samt deres samlede bruttoregistertonnage (BRT), idet de dog forventes at producere samme antal ton-sømil.
Considering the situation which is expected to occur by 1990, a slight decrease is predicted in the number and total Gross Tonnage (GT) of trading vessels of over 100 GT in the world fleet, although they are expected to produce the same number of ship-miles.
