Aframax tankers have experienced a “dramatic” evolution of rates in the North Sea market, according to shipbroker Barry Rogliano Salles (BRS).

The French shop said that an already “light-ish” tonnage list grew very difficult to navigate as tonnage quickly disappeared under the radar, while charterers piled in with a flurry of cargoes.

Rates have risen by between Worldscale (WS) 60 and 70 points in a week, with more potential for rises.
