"If the sea is blue... is also thanks to the yellow fleet"


Since 1986, on the basis of an agreement with the Administration (today Environment Ministry) has been providing emergency antipollution services for the safeguarding of Italian seas and coasts, with a fleet consisting of coasting and oceangoing vessels deployed in Italy in major ports and in the vicinity of the most sensitive areas of the sea from the environmental point of view. The oceangoing vessels are endowed with high oil recovery capacity, and equipped with technologically advanced apparatus for the recovery of pollutants, remediation of marine areas, and operations to respond to fires, to tow vessels involved in accidents to safety, and to prevent pollution. The coasting vessels operate within 20 miles from the coast and can work in relatively narrow, shallow areas of sea; they are equipped for remediation of the coasts. Castalia is structured with a National Operating Centre in Roma in connection with the Environment Ministry, and peripheral facilities situated in ports for Maritime Management, as well as eight supply depots holding specialist equipment. Since 2015 it has been performing daily patrols service for the oil rigs in the Adriatic Sea and the Strait of Sicily.



  • 9 Offshore Vessels
  • 27 Coastal Vessels


  • 1 Centre for Coordination with Rome headquarters
  • 15 Peripheral Centres in the major Italian ports
  • 8 supply depots


OIL SPILL DETECTION The oceangoing vessels are equipped with RADAR systems dedicated to OIL SPILL DETECTION, able to detect and follow oil pollution even by night and with poor visibility.


FLEET TRACKING SISTEM All the vessels of the fleet are equipped with satellite systems enabling real-time monitoring of the activities.
