Nautical feasibility, manoeuvring and mooring studies for the development of all the large Spanish ports (Barcelona, Tarragona, Castellón, Sagunto, Valencia, Alicante, Cartagena, Almería, Málaga, Algeciras, Cádiz, Huelva, Bilbao, Gijón, Ferrol, Punta Langosteira (A Coruña), Las Palmas and Granadilla (Tenerife)). Since the 1990s, many of the largest Spanish ports have undertaken large expansion works (new basins, exterior ports) designed in accordance with the ROM criteria for safety and efficiency and supported by specific simulation studies.
