Port expansion, Gijón

The Spanish port of Gijón on the Bay of Biscay processes more than 12 million tonnes of bulk goods annually. With the expansion of global trade and increasing ship sizes, the terminal was lacking capacity to handle the traffic. The maximum draft for the ships of 18 meters is another obstacle to the development of the port. So the Port Authority of Gijón developed a plan for additional modern facilities in an area measuring 145 hectares to the north of the existing port. This includes a bulk terminal with a transfer capacity of more than 25 million tons and a storage area measuring 60 hectares for a maximum of 2 million tons of coal and iron ore a year.

Port development, Sevilla

Seville is located 80 km land inwards and it is Spain’s only commercial river port. Access is along the Rio Guadalquivir. The current dimensions and depth of the port impose limitations on the breadth and draughts of the vessels that use it, putting the future of the port at risk. So the Port Authority developed a New Maritime Approach that provides for the deepening and widening of the approaches to the port.
