Port

According to the American Association of Port Authorities, the port of Antwerp was the seventeenth largest (by tonnage) port in the world in 2005 and second only to Rotterdam in Europe. It handled 235.2 million tons of cargo in 2018. Importantly it handles high volumes of economically attractive general and project cargo, as well as bulk cargo. Antwerp's docklands, with five oil refineries, are home to a massive concentration of petrochemical industries, second only to the petrochemical cluster in Houston, Texas. Electricity generation is also an important activity, with four nuclear power plants at Doel, a conventional power station in Kallo, as well as several smaller combined cycle plants. There is a wind farm in the northern part of the port area. There are plans to extend this in the period 2014–2020. The old Belgian bluestone quays bordering the Scheldt for a distance of 5.6 km (3.5 mi) to the north and south of the city centre have been retained for their sentimental value and are used mainly by cruise ships and short sea shipping.
