Rhine shipping costs jump 33% as heatwave cuts vessel loads to 20% capacity. Tanker barge rates from Rotterdam to Karlsruhe hit €70 a ton.
Low water levels from a heatwave are forcing cargo vessels on the Rhine river in Germany to sail part-loaded, pushing up freight costs, commodity traders said Monday.
Shallow water at the Kaub chokepoint and south of Duisburg means vessel operators are adding surcharges to compensate for reduced cargo capacity. Loads now have to be split across multiple ships, traders said. Vessels are often able to carry only 20% of their normal load.
Tanker barges can currently haul about 1,200 metric tons through Duisburg and just 460 tons at Kaub, traders said. The cost of barge transport from Rotterdam to Karlsruhe has climbed to around €60 to €70 a ton, up from roughly €45 at the end of June.
The Rhine is a key route for grains, minerals, ores, coal, and oil products including heating oil. Dry weather and a continued heatwave in catchment areas mean relief is not imminent, traders said, though rain is forecast from Friday.
German companies faced supply bottlenecks and production problems in summer 2022 after drought and heatwave drove Rhine water levels to unusually low depths.
