Rotterdam port risks falling out of the top 10 seaports rankings worldwide over the next few years.

Other ports around the globe, particularly in Asia, are growing at a faster pace, the port authority’s director Allard Castelein told the Financieele Dagblad on Friday.

Rotterdam was the largest seaport in the world until 2004, but lost its top spot to Chinese ports. Ningho & Zhoushan was the biggest port in 2014, when Rotterdam was ranked eighth.

Castelein said there is a projected 1% decline in throughput in the port this year over the record 466 million tonnes recorded in 2015. He attributed this to lower transhipments of coal and iron ore. There was a slight increase in the number of containers handled.

‘A port is more than tonnes,’ Castelein said, adding Rotterdam is striving to attract more companies producing value added goods. Another goal is to reduce the use of fossil fuels in the area’s petrochemicals industry, he said.
