HAMBURG (Reuters) -A heat wave in western Europe has lowered water levels on Germany's Rhine River, hampering shipping and raising freight costs for cargo owners due to additional surcharges as their vessels were unable to sail fully loaded, commodity traders said on Monday.
Low water has limited shipping on all of the river south of Duisburg and Cologne, including the chokepoint of Kaub, traders said.
At Kaub, cargo vessels could only sail about 50% full, at Duisburg and Cologne between 40-50% full.
Shallow water leads vessel operators to impose surcharges on freight rates to compensate for the vessels being unable to sail fully loaded, which raises the need for additional vessels to move consignments and increases costs for cargo owners.
Still, cargo is being delivered, with loads being carried by several vessels instead of one, traders said.
The Rhine is an important shipping route for commodities such as grains, minerals, ores, coal and oil products, including heating oil.
An intense heat wave is again forecast in parts of Germany this week, including in the Rhine area, with temperatures as high as 40 degrees Celsius (104 degrees Fahreinheit) possible in Cologne.
Traders said no improvement was in immediate sight and water levels could fall further.
German companies also faced supply bottlenecks and production problems in the summer of 2022 after a drought and heat wave led to unusually low water levels on the Rhine.

The heat wave has lowered water levels on the Rhine River, limiting shipping to about 50% capacity for cargo vessels at Kaub and between 40-50% at Duisburg and Cologne.
Low water levels lead vessel operators to impose surcharges on freight rates, increasing costs for cargo owners and necessitating more vessels to transport goods.
The Rhine is a crucial shipping route for commodities such as grains, minerals, ores, coal, and oil products, including heating oil.
Traders have indicated that no improvement is in immediate sight, and water levels may continue to fall further.
